TRABALLO EN MARCHA NON ESTÁ REMATADA A VERSIÓN EN GALEGO

O meu portátil é un ordenador Acer 5755G coas siguientes características:

• Core i5 2430M 2.4GHz
• NVIDIA Geforce GT 540M
• 8Gb RAM
• 750Gb HD

Meu portátil equipa unha tarxeta _Nvidia Geforce GT540M_ que resulta pertencer a unha pola morta na árbore de desenrolo de Nvidia.

A gráfica é unha Nvidia Optimus, unha tarxeta híbrida que traballaba perfectamente en Ubuntu 14.04 usando Bumblebee.

No upgrade a Ubuntu Xenial Xerus a miña gráfica deixou de traballar correctamente có método de instalación de _Bumblebee_ que viña usando. E mesmo con todo-los que fun quen de probar.

Ademais atopei problemas insolubles (para min) na instalación do Virtual Box así que decidín voltar a Debian.

Para facer a actualización do sistema optei por desinstalar o dvd e montar no seu sitio un disco SSD nun Caddie para Acer. A instalación foi moi doada, e ainda que o portátil arranca perfectamente de cualquera dos dous discos, finalmente optei por instalar o SSD na bahía interna do HD orixinal e pasar o HD orixinal ao caddie.

Unha vez instalado o novo sistema operativo, o primeiro foi a instalación do Bumblebee para probar que funcionaba normalmente.

sudo apt-get install firmware-linux-nonfree Bumblebee-nvidia primus

Executamos:

sudo dpkg-reconfigure locales

Despois só teremos que cambiar a selección do idioma na configuración de Gnome.

Tra-la reconfiguración teremos que rearrancar Gnome y renomeará todos-los directorios do sistema.

Instalamos aptitude, synaptic e gdebi

sudo apt-get install aptitude
sudo apt-get install synaptic
sudo apt-get install gdebi

Cambiamos as opcións de aptitude para que non instale os paquetes recomendados.

Editamos o ficheiro /etc/apt/sources.list e comentamos as lineas do cdrom.

sudo cat> /etc/apt/sources.list.d/backports.list <<EOF
# backports
deb http://ftp.debian.org/debian/ jessie-backports main contrib non-free
EOF

sudo cat>> /etc/apt/sources.list.d/multimedia.list <<EOF
# multimedia
deb http://www.deb-multimedia.org/ jessie main non-free
EOF

sudo apt-get -y --allow-unauthenticated install --reinstall deb-multimedia-keyring

E actualizamos:

sudo aptitude update

Un editor de menús para Gnome, poderemos xerar os arquivos desktop para cualquera aplicación. Moito mais completo que alacarte a outra alternativa.

sudo apt-get install menulibre

Terminator é un emulador de terminal moi completo y moi flexible. Instalaremolos dende aptitude

sudo aptitude install terminator python-keybinder

Instalado keepass2 dende Debian

sudo aptitude install keepass2

Un sudo en modo gráfico:

sudo aptitude install gksu

Moi importante executar gksu-properties e escoller o modo sudo e non o de su. Evitaremos problemas coa instalación de moitas aplicacións.

Para xestionar discos portátiles, memorias, etc,.

sudo apt-get install ntfs-3g disk-manager

Finanzas en linux

sudo apt-get -t jessie-backports install gnucash

Facede sempre backups!

sudo apt-get install rsync grsync

Baixado o paquete Debian dende a páxina web de Dropbox, instalado o paquete con packageinstall, e decir, simplemente pinchando dende o xestor de ficheiros.

sudo apt-get install rar unrar zip unzip unace bzip2 lzop p7zip p7zip-full p7zip-rar

Mellor que Freemind (na miña opinión). O baile de sempre, descarregar da web, descomprimir en ~/apps e crear o lanzador con MenuLibre. Todo-los ficheiros que tiña feitos con Freemind podense usar directamente co Freeplane.

O cliente de mensaxería de Telegram. Descarregado dende a web, instalado en ~/apps

Instalado o Chrome engadindo as fontes e executando aptitude. Non me lembro como as engadin.

No ficheiro /etc/apt/sources.list.d/google-chrome.list, teño este contido:

###
###
###
###
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

Para instalar executamos:

sudo aptitude install google-chrome-stable
sudo aptitude install chromium

Baixado o zip dende a web oficial, e descomprimido no directorio ~/apps

O ficheiro desktop, que ven incluido no paquete, copieino a ~/.local/share/applications

Baseado na web nix/bsd.

Ainda non rematei a configuración.

A miña aplicación preferida para descarregar torrents

Instalamos dende aptitude

sudo aptitude install deluge
xdg-mime default deluge.desktop x-scheme-handler/magnet

Tiddly é unha wiki auto-contida e moi flexible, ten unha morea de versións, adaptadas para diferentes usos. Usoa dende fai uns anos como caderno de bitácora persoal, pero non estaba a seguir a sua evolución.

Descarreguei:

• Tiddlywiki . A este instaleine tamén os plugins de FontAwesome e WikiMap, este será o meu novo caderno de bitácora.
• GSD5 un TiddlyWiki adaptado a GTD

Ademáis instalei a aplicación TiddlyDesktop, baseada en node webkit que simplifica o tema dos backups das tuas wikis (en teoría).

Como facemos sempre descomprimimos en ~/apps e creamos un lanzador con MenuLibre.

O programa libre para creación e edición de gráficos vectoriais.

apt-cache policy inkscape
apt-get -t jessie-backports install inkscape
aptitude install ink-generator

Imprescidibles para a creación e diseño en 2D e 3D.

Instalado dende os repos con aptitude

apt-get install librecad

apt-get -t jessie-backports install freecad

O programa libre por excelencia de edición e retocado de imáxenes.

Gimp xa estaba instalado por defecto, instalamos ademais o gimp data-extra

sudo aptitude install gimp-plugin-registry gimp-texturize gimp-data-extras gimp-gap

Un programa de captura de pantallas que permite editalas rápidamente:

sudo aptitude install shutter libgoo-canvas-perl

É unha aplicación java para facer bocetos de páxinas web, probablemente non a necesitas.

Descarregar a derradeira versión (paquete Debian) dende la página web. Instalamolo e listo. Pode dar problemas si usamos Iceweasel, xa que o paquete depende de Firefox. Mais info aquí

Se gostas da fotografía e/ou tes unha cámara reflex precisas probar estas aplicacións.

sudo aptitude install icc-profiles icc-profiles-free
sudo aptitude install rawtherapee darktable

Para facer pelis de stopmotion

sudo aptitude install stopmotion vgrabbj dvgrab

TODO: Probar qStopmotion

sudo aptitude install clementine gstreamer0.10-plugins-bad
sudo aptitude install decibel-audio-player audacity soundconverter

Instalamos gpodder para xestionar os nosos podcast, ainda que non é imprescindible, Clementine tamén nos vale como xestor de podcasts.

sudo aptitude install gpodder

Cliente de Spotify, se é que o usas.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys BBEBDCB318AD50EC6865090613B00F1FD2C19886

Pandoc é un traductor entre formatos de documento. Está escrito en Python e é incriblemente útil. De feito, este documento está escrito usando o Pandoc.

Instalado o Pandoc descarregando o paquete deb dende a páxina web do proxecto Pandoc.

Descargamos las plantillas desde o repo executando os seguintes comandos:

cd ~/.pandoc
git clone https://github.com/jgm/pandoc-templates templates

Zotero é un programa que permite manter unha ou varias bibliografías con referencias a libros, páxinas web ou documentos electrónicos.

Instalado o Zotero Standalone dende a páxina web do programa

O LaTeX do Debian está un pouquiño anticuado, se queres usar unha versión actualizada terás que aplicar esta receta.

cd ~
mkdir tmp
cd tmp
wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz
tar xzf install-tl-unx.tar.gz
cd install-tl-xxxxxx

A parte xxxxxx varía en función do estado da derradeira versión do LaTeX dispoñible.

sudo ./install-tl

Unha vez lanzada a instalación poderemos desmarcar as opcións que instalan a documentación e as fontes. Teremos que consultar a documentación on line pero aforraranos prácticamente o 50% do espacio necesario. No meu caso sen doc nin src ocupa 2,3Gb

mkdir -p /opt
sudo ln -s /usr/local/texlive/2016/bin/* /opt/texbin

Para rematar a instalación engadimos /opt/texbin ao path.

Xa temos o texlive instalado, agora precisamos que o xestor de paquetes o rexistre como instalado.

sudo apt-get install equivs --no-install-recommends
mkdir -p /tmp/tl-equivs && cd /tmp/tl-equivs
equivs-control texlive-local

Para facelo mais doado podemos descarregar un ficheiro xa preparado, executando:

wget http://www.tug.org/texlive/files/debian-equivs-2015-ex.txt
/bin/cp -f debian-equivs-2015-ex.txt texlive-local

Editamos a versión e

equivs-build texlive-local
sudo dpkg -i texlive-local_2015-1_all.deb

Todo listo, agora podemos instalar cualquer paquete que dependa de texlive

Para deixar dispoñibles as fuentes opentype y truetype que veñen con texlive para o resto de aplicacións:

sudo cp $(kpsewhich -var-value TEXMFSYSVAR)/fonts/conf/texlive-fontconfig.conf /etc/fonts/conf.d/09-texlive.conf
gksudo gedit /etc/fonts/conf.d/09-texlive.conf

Borramos a línea:

<dir>/usr/local/texlive/2016/texmf-dist/fonts/type1</dir>

E executamos:

sudo fc-cache -fsv

Para actualizar o noso latex á derradeira versión de todo-los paquetes:

sudo /opt/texbin/tlmgr update --self
sudo /opt/texbin/tlmgr update --all

Tamén podemos lanzar o instalador gráfico con:

sudo /opt/texbin/tlmgr --gui

Para usar o instalador gráfico hai que instalar previamente:

sudo apt-get install perl-tk --no-install-recommends

mkdir -p ~/.local/share/applications
/bin/rm ~/.local/share/applications/tlmgr.desktop
cat > ~/.local/share/applications/tlmgr.desktop << EOF
[Desktop Entry]
Version=1.0

GenericName=Package Manager
Exec=gksu -d -S -D "TeX Live Manager" '/opt/texbin/tlmgr -gui'
Terminal=false
Type=Application
Icon=system-software-update
EOF

Ollo! Hai que deixar instalado o gksu (ainda que debería estar de antes se sigues este doc)

sudo aptitude install gksu

Emacs: o mellor editor.

Instalado emacs dende os repos:

sudo aptitude install emacs

Instalamos los paquetes markdown-mode, mardown-plus y pandoc-mode desde el menú de gestión de paquetes de emacs.

Como estou a aprender a linguaxe de programación D, instalamos tamén d-mode y flymake-d (posiblemente ti non os precisas)

Despois de probar flymake e flycheck gostei mais de flycheck Hai unha sección de configuración no fichero .emacs de exemplo para cada un deles, pero a de flymake está comentada.

Configuramos o ficheiro .emacs definindo algunhas preferencias, algunhas funcións útiles e engadimos oríxenes extra de paquetes.

Teremos que usar Java para executar varios programas, preferimos a versión aberta.

apt-get install openjdk-7-jre icedtea-7-plugin

https://dlang.org/ e unha linguaxe de programación de sistemas cunha sintáxis similar a de C e tipado estático. Combina a eficiencia, o control e a potencia de modelado coa seguridade e a productividade.

Configurado d-apt, instalados todo-los programas do repo:

sudo wget http://master.dl.sourceforge.net/project/d-apt/files/d-apt.list -O /etc/apt/sources.list.d/d-apt.list
sudo apt-get update && sudo apt-get -y --allow-unauthenticated install --reinstall d-apt-keyring && sudo apt-get update

Instalamos todo-los programas asociados.

sudo aptitude install dmd dub dcd dfix dfmt dscanner textadept

Unha vez instalado o DCD temos que configuralo creando el ficheiro ~/.config/dcd/dcd.conf có contido seguinte:

/usr/include/dmd/druntime/import
/usr/include/dmd/phobos

Podemolo probar con:

dcd-server &
echo | dcd-client --search toImpl

Instalado con

sudo aptitude install gdc

Instalado con:

sudo aptitude install ldc

Para poder executar aplicacións baseadas en Vibed, temos que instalar:

Un entorno de programación baseado en java e ideal para aprender a programar dende cero.

Baixamos os paquetes das respectivas páxinas web, descomprimimimos en ~/apps/ y creamos os desktop file con Menulibre

Bajamos el paquete comprimido de la página web del proyecto.

Descomprimimos en ~/apps

Bajamos al directorio de la aplicación y ejecutamos:

sudo  scripts/linux/debian/install_dependencies.sh
sudo  scripts/linux/debian/install_codecs.sh

cd scripts/linux
./compileOF.sh -j2

cd OF/examples/graphics/polygonExample
make
make Run

cd OF/scripts/linux
./compilePG.sh

Va a instalar un montón de dependencias, hay que tomarlo con calma.

Al final también va a añadir una linea al fichero ~/.profile

export PG_OF_PATH=/home/salvari/apps/of/of_v0.9.3_linux64_release

De partida tenemos instalado dos versiones: python y python3

python -V
Python 2.7.9

python3 -V
Python 3.4.2

Instalado python-pip y python-virtualenv desde aptitude.

sudo aptitude install python-pip python-virtualenv virtualenv

Instalamos a mayores Ananconda, es la forma fácil de poder usar ipython notebook. De hecho me he instalado dos versiones la que incluye el python2 y la que incluye el python3.

Las instalaciones de Anaconda son redundantes, basta con instalar uno de ellos. En cualquier caso para realizar la instalación basta con descargar los scripts de instalación desde la página web de Anaconda.

bash Anaconda3-4.2.0-Linux-x86_64.sh
bash Anaconda2-4.2.0-Linux-x86_64.sh

Los he dejado instalados en ~/apps/anaconda2 y ~/apps/anaconda3

Cada una de estas instalaciones incorpora su propia versión de Python. Para usarlas tenemos que cambiar nuestro PATH para que el Python deseado sea el primero que se selecciona.

Por ejemplo para activar anaconda3 en bash:

export PATH="~/apps/anaconda3/bin:$PATH"

Para hacer lo mismo en fish:

set -x PATH ~/apps/anaconda3/bin $PATH

Creamos un entorno conda con Python 2.7.x

conda create -n gl-env python=2.7 anaconda

Activamos el nuevo entorno (todo esto lo hice en bash, en fish hay un problemilla con el entorno conda mas info)

bash
source activate gl-env

En el futuro esto es todo lo que tendremos que hacer activar el entorno conda donde estamos instalando el iPython.

Nos aseguramos de tener pip al dia:

conda update pip

Instalamos la biblioteca GraphLab Create. Esta biblioteca se supone que es fácil de usar pero está sujeta a licencia. ²⁾

Una vez registrado en la página web te pasan un número de registro que tienes que usar para instalar la biblioteca.

pip install --upgrade --no-cache-dir https://get.graphlab.com/GraphLab-Create/2.1/your registered email address here/your product key here/GraphLab-Create-License.tar.gz

Y para terminar instalamos iPython ³⁾:

conda install ipython-notebook

Desde ahora basta con activar el entorno que hemos creado para tener acceso al iPython.

source activate gl-env

ipython notebook

source deactivate gl-env

# Create a virtual environment named e.g. gl-env
virtualenv gl-env

# Activate the virtual environment
source gl-env/bin/activate

# Make sure pip is up to date
pip install --upgrade pip

# Install IPython Notebook (optional)
pip install "ipython[notebook]"

# Install Jupyter Notebook (optional)
pip install "jupyter"


# Install your licensed copy of GraphLab Create
pip install --upgrade --no-cache-dir https://get.graphlab.com/GraphLab-Create/2.1/your registered email address here/your product key here/GraphLab-Create-License.tar.gz

Instalamos elpy desde el gestor de paquetes de Emacs, concretamente desde el repo marmalade

Hay que habilitar elpy en el fichero ~/.emacs para ello añadimos la linea

(elpy enable)

flycheck chequea el código python conviene instalar:

sudo pip install pylint

Estudiar esto con calma https://elpy.readthedocs.io/en/latest

Desde la página web oficial de web2py descargamos el source code para usuarios normales.

Yo he descomprimido el framework en ~/apps/web2py

Para que el framework soporte ssl convine generar los siguientes certificados:

openssl genrsa -out server.key 2048
openssl req -new -key server.key -out server.csr

Country Name (2 letter code) [AU]:ES
State or Province Name (full name) [Some-State]:CORUNA
Locality Name (eg, city) []:CORUNA
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Mikasa
Organizational Unit Name (eg, section) []:salvari
Common Name (e.g. server FQDN or YOUR name) []:salvari
Email Address []:salvari@gmail.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:secret1t05
An optional company name []:Mikasa

Ahora ejecutamos:

openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Ahora deberíamos dejar los ficheros server.key, server.csr y server.crt en el directorio raiz de web2py y ya podremos arrancar el framework con los siguientes parámetros:

python web2py.py -a 'admin_password' -c server.crt -k server.key -i 0.0.0.0 -p 8000

Y ya podemos acceder nuestro server en la dirección https://localhost:8000

Tampoco está de más instalar las librerías de graphviz:

sudo aptitude install python-pygraphviz

Bajamos los paquetes de la página web , descomprimimimos en ~/apps/arduino.

Creamos un link al directorio del software que hemos descargado:

cd ~/apps/arduino
ln -s arduino-x.y.z current

La primera ves que instalamos será necesario crear el desktop file con Menulibre con las actulizaciones no será necesario, siempre y cuando apunte a ~/apps/arduino/current

Tenemos el paquete de instalación disponible en su página web

Ejecutamos el programa de instalación. El programa descargará los paquetes Debian necesarios para dejar el IDE y los compiladores instalados.

Al acabar la instalación he tenido que crear el directorio ~/Pinguino/v11, parece que hay algún problema con el programa de instalación y no lo crea automáticamente.

El programa queda correctamente instalado en /opt y arranca correctamente, habrá que probarlo con los micros.

Instalamos desde backports:

sudo aptitude install -t jessie-backports kicad

Vamos a instalar a mayores algunas librerias de KiCAD, para poder crear Shields de Arduino.

• Freetronics una libreria que no solo incluye Shield para Arduino sino una completa colección de componentes que nos permitirá hacer proyectos completos. Freetronics es una especie de BricoGeek australiano, publica tutoriales, vende componentes, y al parecer mantiene una biblioteca para KiCAD. La biblioteca de Freetronics se mantiene en un repo de github. Lo suyo es incorporarla a cada proyecto, por que si la actualizas se pueden romper los proyectos que estes haciendo.
• eklablog Esta biblioteca de componentes está incluida en el github de KiCAD, así que teoricamente no habría que instalarla en nuestro disco duro.

apt-get install apt-transport-https ca-certificates

edit docker.list with
deb https://apt.dockerproject.org/repo debian-jessie main

apt-cache policy docker-engine   -- comprobamos que todo está bien.


sudo apt-get install docker-engine   -- da un error en makedev por udev activo


sudo service docker start

sudo docker run hello-world   - todo bien

sudo gpasswd -a salvari docker

Tenemos que:

• Añadir el fichero virtualbox.list al directorio /etc/apt/sources.list.d
• Bajarnos y añadir a nuestro llavero las claves públicas de Oracle
• Actualizar la lista de paquetes
• Instalar virtualbox
• Añadir nuestro usuario al grupo vboxuser (no tengo claro que esto sea necesario)

echo "deb http://download.virtualbox.org/virtualbox/debian jessie contrib" \
|sudo tee /etc/apt/sources.list.d/virtualbox.list wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- \
| sudo apt-key add - sudo apt-get update sudo apt-get install virtualbox-5.1 sudo gpasswd -a salvari vboxusers

Una vez instalado el virtualbox tenemos que instalarnos el pack de extensiones, es muy importante descargar el pack correspondiente a nuestra versión desde la página web de descargas

Sin más que hacer doble click en el fichero descargado lo instalaremos en nuestra instancia de Virtualbox (necesitamos la contraseña de administración).

• 2 Gb de ram
• Create virtual hard disk
• 10Gb dinamically allocated
• Settings → System→Boot Order: Quitamos el floppy
• Storage → Add IDE Controller→Add Optical Disk → Choose Disk → ISO Image
• Instalamos Windows en Inglés y con teclado en español

Una vez instalado el SO Windows instalamos las Guest Additions.

Los dos son muy interesantes. He usado zsh casi un año, ahora voy a probar fish.

Instalamos fish desde aptitude con:

sudo aptitude install fish

Instalamos oh-my-fish

curl -L https://github.com/oh-my-fish/oh-my-fish/raw/master/bin/install > install
fish install
rm install

chsh -s `which fish`

Igualmente instalamos zsh:

sudo aptitude install zsh

Vamos a usar antigen así que nos lo clonamos en _~/apps/

cd ~/apps
git clone https://github.com/zsh-users/antigen

Y editamos el fichero ~/.zshrc para que contenga:

source ~/apps/antigen/antigen.zsh

# Load the oh-my-zsh's library.
antigen use oh-my-zsh

# Bundles from the default repo (robbyrussell's oh-my-zsh).
antigen bundle git
antigen bundle command-not-found
antigen bundle autojump
antigen bundle extract
# antigen bundle heroku
# antigen bundle pip
# antigen bundle lein


# Syntax highlighting bundle.
antigen bundle zsh-users/zsh-syntax-highlighting

# git
antigen bundle arialdomartini/oh-my-git
antigen theme arialdomartini/oh-my-git-themes oppa-lana-style

# autosuggestions
antigen bundle tarruda/zsh-autosuggestions

#antigen theme agnoster

# Tell antigen that you're done.
antigen apply

# append to path
path+=('/home/salvari/apps/julia/current/bin/')
# prepend
# path=('/home/salvari/bin/' $path)
# export PATH

Antigen ya se encarga de descargar todo lo que queramos utilizar en zsh.

Nos queda arreglar las fuentes para que funcione correctamente la linea de estado en los repos de git. Necesitamos una fuente Awesome

Nos bajamos unas cuantas fuentes que soporten los iconos Awesome.

cd ~/tmp
git clone https://github.com/abertsch/Menlo-for-Powerline
git clone https://github.com/powerline/fonts

mkdir ~/.fonts
cp someFontFile ~/.fonts/
fc-cache -vf ~/.fonts/

Descargamos el paquete binario desde la página web.

• Cambiar permisos en directorio /lib/vrt/
• Instalado lib-canberra-module desde aptitude
• Es necesario instalar freeglut

Instalado desde aptitude.

Descargamos desde github

Descargamos desde la pagina web

sudo aptitude install python3-pyqt5
sudo dpkg -i Cura-2.1.3-Linux.deb

sudo apt-get install python-serial python-wxgtk2.8 python-pyglet python-numpy \
cython python-libxml2 python-gobject python-dbus python-psutil python-cairosvg git

python setup.py build_ext --inplace

Instalamos el paquete apache2

sudo aptitude install apache2

Si abrimos el navegador y visitamos http://localhost/ veremos la página de Apache.

El directorio raiz por defecto de Apache en Debian es /var/www, y el fichero de configuración principal es /etc/apache2/apache2.conf. Hay ficheros de configuración adicionales en el directorio /etc/apache2 y sus subdirectorios. Por ejemplo:

• /etc/apache2/mods-enabled
• /etc/apache2/sites-enabled
• /etc/apache2/conf-enabled

Además del Apache vamos a dejar instalado el php5

sudo aptitude install php5 libapache2-mod-php5

Hay que reiniciar el servicio: sudo service apache2 restart

Si creamos un fichero /var/www/html/info.php, que contenga las lineas:

<?php
phpinfo();
?>

Podemos ver en el siguiente enlace http://localhost/info.php si el php funciona correctamente.

Módulos de php relacionados con mysql:

sudo aptitude install php5-mysqlnd php5-curl php5-gd php5-intl php-pear \
php5-imagick php5-imap php5-mcrypt php5-memcache php5-pspell php5-recode \
php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

TODO

Instalamos desde aptitude mysql-server.5.6

Opcionalmente (y muy recomendable)

mysql_secure_instalallation

Cambiamos el fichero mysql.conf.d/mysqld.cnf

# max_allowed_packet      = 16M
max_allowed_packet  = 500M

Reiniciamos el servicio:

/etc/init.d/mysql restart

Descargamos el paquete desde la página web y lo descomprimimos en ~/apps, también tendremos que descargar el conector de mysql para java, por ejemplo desde aquí

Una vez instalado, creamos el desktop-file con MenuLibre y configuramos el driver MySQL añadiendo el path a donde hayamos dejado el conector java.

PENDIENTE

Para usar la Orange Pi Zero tendremos que crear imágenes arrancables en tarjetas micro SD.

Dependiendo de donde conectemos la tarjeta tendremos que usar diferentes rutas. En el procedimiento descrito a continuación ${card} será la ruta al dispositivo de la tarjeta y ${p} la partición (si la hay).

Si la tarjeta se conecta via adaptador USB, linux la va a asociar a un dispositivo /dev/sdx, por ejemplo en mi portátil el disco duro es /dev/sda las distintas particiones serán /dev/sda1, /devb/sda2, etc.

Si conectamos una memoria con un adaptador USB linux la podría mapear en /dev/sdb por ejemplo.

Si la memoria se conecta mediante una ranura SD, linux la asociará a un dispositivo /dev/mmcblk0 o /dev/mmcblk1, etc. etc. Dependerá de la ranura usada. Las particiones en este tipo de dispositivos tienen rutas como por ejemplo /dev/mmcblk0p1.

Los datos se pueden almacenar directamente en la memoria SD o en una partición creada en la memoria.

Resumiendo:

• ${card} será /dev/sdb o /dev/mmcblk0
• ${card}${p} será /dev/sdb1 o /dev/mmcblk0p1

Antes de seguir adelante hay que estar completamente seguro del dispositivo asociado a nuestra memoria SD para no armar ningún estropicio.

Hay varias comprobaciones que se pueden hacer:

dmesg |tail nos permitirá echar un ojo a los últimos mensajes en el log del sistema. Si acabamos de insertar la memoria veremos el dispositivo usado.

sudo fdisk -l nos permite ver las particiones montadas en nuestro linux, por ejemplo con mi SD en la ranura SD de mi portatil la salida es (entre otras cosas, he obviado las particiones de los discos duros):

Disk /dev/mmcblk0: 7.4 GiB, 7948206080 bytes, 15523840 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

cat /proc/partitions también nos dará una lista de particiones, en mi portátil las que interesan son:

 179        0    7761920 mmcblk0
 179        1    7757824 mmcblk0p1

Descargamos la imagen de Jessie adaptada a la Orange Pi Zero desde la página https://www.armbian.com/download/

Descomprimimos la imagen y la grabamos en la tarjeta SD con el comando:

sudo dd if=./Armbian_5.24_Orangepizero_Debian_jessie_3.4.113.img of=/dev/mmcblk0

Insertamos la tarjeta en la Orange Pi y le damos alimentación. El primer arranque llevará alrededor de tres minutos, y tras ese tiempo aun hará falta un minuto más para poder hacer login. Este retardo es debido a que el sistema intentará actualizar la lista de paquetes y creará un area de swap de emergencia en la SD, y además cambiará el tamaño de la partición que hemos creado para ocupar todo el espacio libre en la SD.

De momento solo la he arrancado y efectivamente las particiones han cambiado tras el arranque así que tiene buena pinta.

Volvemos a insertar la SD en la Orange Pi y la conectamos con un cable ethernet al router de casa. El Armbian viene configurado por defecto para obtener su IP desde un servidor DHCP.

Como mi cutre-router no me da información de las IP asignadas usamos nmap:

nmap -sP 192.168.0.0 /24

Con eso averiguamos la IP asignada a la Orange Pi Zero y ya podemos hacer login con:

ssh root@192.168.0.109

¡Y ya estamos!

Lo primero es poner al dia el sistema:

apt-get update
apt-get upgrade

Si quieres puedes reconfigurar el time zone:

dpgk-reconfigura tzdata

Vamos a comprobar que todo va bien:

root@orangepizero:~# iwconfig
lo        no wireless extensions.

tunl0     no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

eth0      no wireless extensions.

Todo tiene buena pinta, vamos a ver si detecta WIFIs:

root@orangepizero:~# iwlist wlan0  scan |grep ESSID
                    ESSID:"wificlientesR"
                    ESSID:"casa_de_verano"
                    ESSID:"MOVISTAR_BEEF"
                    ESSID:"wificlientesR"
                    ESSID:"R-wlan90"
                    ESSID:"MOVISTAR_BAAF"
                    ESSID:"ababab"
                    ESSID:"WLAN 77"
                    ESSID:"castillo"
                    ESSID:"unaWifi"
                    ESSID:""
                    ESSID:"mikasa"

Para configurar el wifi echamos un ojo al fichero /etc/network/interfaces pero en ese mismo fichero encontramos el aviso:

# Armbian ships with network-manager installed by default. To save you time
# and hassles consider using 'sudo nmtui' instead of configuring Wi-Fi settings
# manually.

Así que basta con ejecutar sudo nmtui y ya podemos dar de alta nuestra wifi (yo la prefiero con IP estática).

Ejecutamos ifconfig y ya vemos nuestro nuevo interface configurado:

ifconfig

wlan0     Link encap:Ethernet  HWaddr a4:7c:f2:9a:97:7c
          inet addr:192.168.0.120  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::a67c:f2ff:fe9a:977c/64 Scope:Link

Bajamos la imagen con nuestro cliente torrent favorito desde aquí, no os molesteis en clonar el directorio, hay que bajarse la imagen.

sudo dd if=./Mediacenter-AikonCWD-v6.img  of=/dev/mmcblk0 bs=4M

Arrancamos con la toma ethernet conectada al router y nos conectamos tras averigurar la IP con nmap (ver Orange Pi Zero)

Una vez instalado los pasos recomendados:

• Cambiar la password de root: passwd
• Fijar una IP estática: Editamos el fichero /etc/dhcpcd.conf, ya de paso configuramos la IP estática para la WIFI

interface eth0
static ip_address=192.168.0.125/24
static routers=192.168.0.1
static domain_name_servers=8.8.8.8

interface wlan0
static ip_address=192.168.0.126/24
static routers=192.168.0.1
static domain_name_servers=8.8.8.8

• Una vez cambiado el fichero hay que reiniciar con shutdown -r now
• Configurar la WIFI, en esta parte damos por supuesto que tenemos la wifi con WPA activado.
• Echamos un ojo a nuestro interfaz radio con iwconfig, si aparece el wlan0 todo va bien.

wlan0     IEEE 802.11bgn  ESSID:off/any
          Mode:Managed  Access Point: Not-Associated   Tx-Power=31 dBm
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

• Tenemos que editar el fichero /etc/network/interfaces y asegurarnos de tener el wlan0 como sigue:

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

• Ahora vamos a editar el fichero de configuración de wpa_supplicant, es decir /etc/wpa_supplicant/wpa_supplicant.conf y añadir un bloque network que sea como el que va a continuación, de paso he cambiado el country a “ES”, asi que queda así:

country=ES
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
  ssid="YOURSSID"
  psk="YOURPASSWORD"
}

• Un reinicio y listos: shutdown -r now

Section 2 -- Scope.

  a. License grant.

       1. Subject to the terms and conditions of this Public License,
          the Licensor hereby grants You a worldwide, royalty-free,
          non-sublicensable, non-exclusive, irrevocable license to
          exercise the Licensed Rights in the Licensed Material to:

            a. reproduce and Share the Licensed Material, in whole or
               in part; and

            b. produce, reproduce, and Share Adapted Material.

       2. Exceptions and Limitations. For the avoidance of doubt, where
          Exceptions and Limitations apply to Your use, this Public
          License does not apply, and You do not need to comply with
          its terms and conditions.

       3. Term. The term of this Public License is specified in Section
          6(a).

       4. Media and formats; technical modifications allowed. The
          Licensor authorizes You to exercise the Licensed Rights in
          all media and formats whether now known or hereafter created,
          and to make technical modifications necessary to do so. The
          Licensor waives and/or agrees not to assert any right or
          authority to forbid You from making technical modifications
          necessary to exercise the Licensed Rights, including
          technical modifications necessary to circumvent Effective
          Technological Measures. For purposes of this Public License,
          simply making modifications authorized by this Section 2(a)
          (4) never produces Adapted Material.

       5. Downstream recipients.

            a. Offer from the Licensor -- Licensed Material. Every
               recipient of the Licensed Material automatically
               receives an offer from the Licensor to exercise the
               Licensed Rights under the terms and conditions of this
               Public License.

            b. Additional offer from the Licensor -- Adapted Material.
               Every recipient of Adapted Material from You
               automatically receives an offer from the Licensor to
               exercise the Licensed Rights in the Adapted Material
               under the conditions of the Adapter's License You apply.

            c. No downstream restrictions. You may not offer or impose
               any additional or different terms or conditions on, or
               apply any Effective Technological Measures to, the
               Licensed Material if doing so restricts exercise of the
               Licensed Rights by any recipient of the Licensed
               Material.

       6. No endorsement. Nothing in this Public License constitutes or
          may be construed as permission to assert or imply that You
          are, or that Your use of the Licensed Material is, connected
          with, or sponsored, endorsed, or granted official status by,
          the Licensor or others designated to receive attribution as
          provided in Section 3(a)(1)(A)(i).

  b. Other rights.

       1. Moral rights, such as the right of integrity, are not
          licensed under this Public License, nor are publicity,
          privacy, and/or other similar personality rights; however, to
          the extent possible, the Licensor waives and/or agrees not to
          assert any such rights held by the Licensor to the limited
          extent necessary to allow You to exercise the Licensed
          Rights, but not otherwise.

       2. Patent and trademark rights are not licensed under this
          Public License.

       3. To the extent possible, the Licensor waives any right to
          collect royalties from You for the exercise of the Licensed
          Rights, whether directly or through a collecting society
          under any voluntary or waivable statutory or compulsory
          licensing scheme. In all other cases the Licensor expressly
          reserves any right to collect such royalties.


Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

  a. Attribution.

       1. If You Share the Licensed Material (including in modified
          form), You must:

            a. retain the following if it is supplied by the Licensor
               with the Licensed Material:

                 i. identification of the creator(s) of the Licensed
                    Material and any others designated to receive
                    attribution, in any reasonable manner requested by
                    the Licensor (including by pseudonym if
                    designated);

                ii. a copyright notice;

               iii. a notice that refers to this Public License;

                iv. a notice that refers to the disclaimer of
                    warranties;

                 v. a URI or hyperlink to the Licensed Material to the
                    extent reasonably practicable;

            b. indicate if You modified the Licensed Material and
               retain an indication of any previous modifications; and

            c. indicate the Licensed Material is licensed under this
               Public License, and include the text of, or the URI or
               hyperlink to, this Public License.

       2. You may satisfy the conditions in Section 3(a)(1) in any
          reasonable manner based on the medium, means, and context in
          which You Share the Licensed Material. For example, it may be
          reasonable to satisfy the conditions by providing a URI or
          hyperlink to a resource that includes the required
          information.

       3. If requested by the Licensor, You must remove any of the
          information required by Section 3(a)(1)(A) to the extent
          reasonably practicable.

  b. ShareAlike.

     In addition to the conditions in Section 3(a), if You Share
     Adapted Material You produce, the following conditions also apply.

       1. The Adapter's License You apply must be a Creative Commons
          license with the same License Elements, this version or
          later, or a BY-SA Compatible License.

       2. You must include the text of, or the URI or hyperlink to, the
          Adapter's License You apply. You may satisfy this condition
          in any reasonable manner based on the medium, means, and
          context in which You Share Adapted Material.

       3. You may not offer or impose any additional or different terms
          or conditions on, or apply any Effective Technological
          Measures to, Adapted Material that restrict exercise of the
          rights granted under the Adapter's License You apply.


Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
     to extract, reuse, reproduce, and Share all or a substantial
     portion of the contents of the database;

  b. if You include all or a substantial portion of the database
     contents in a database in which You have Sui Generis Database
     Rights, then the database in which You have Sui Generis Database
     Rights (but not its individual contents) is Adapted Material,

     including for purposes of Section 3(b); and
  c. You must comply with the conditions in Section 3(a) if You Share
     all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.


Section 5 -- Disclaimer of Warranties and Limitation of Liability.

  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
     ACCURACY, O
