Ubuntu server 10.04 LTS en castellano bajo OpenVZ

La forma más fácil de crear una máquina virtual bajo Linux es usando el sistema de virtualización proporcionada por OpenVZ.

El único problema que plantea esta manera de instalar máquinas virtuales es que las plantillas están configuradas por defecto con zonas horarias, idiomas, etc que no nos interesan.

En este documento instalaremos una plantilla de Ubuntu server 10.04 LTS y la configuraremos para que use tanto la configuración local española como su zona horaria. Presupondremos instalado y funcionando OpenVZ en el sistema anfitrión.

El primer paso será descargar la plantilla de http://download.openvz.org/template/precreated/ y colocarla en la ruta adecuada:

root@anibal:~# wget -O "/var/lib/vz/template/cache/ubuntu-10.04-x86.tar.gz" "http://download.openvz.org/template/precreated/ubuntu-10.04-x86.tar.gz"
--09:01:21--  http://download.openvz.org/template/precreated/ubuntu-10.04-x86.tar.gz
           => '/var/lib/vz/template/cache/ubuntu-10.04-x86.tar.gz'
Resolviendo download.openvz.org... 64.131.90.11
Conectando a download.openvz.org|64.131.90.11|:80... conectado.
Petición HTTP enviada, esperando respuesta... 200 OK

100%[==============================================>] 137,211,613    1.88M/s    ETA 00:00

09:02:15 (2.41 MB/s) - `/var/lib/vz/template/cache/ubuntu-10.04-x86.tar.gz' guardado [137211613/137211613]

El segundo paso es crear la máquina virtual usando la plantilla que acabamos de descargar. Hay que fijarse que en el parámetro --ostemplate se omite la extensión ".tar.gz" de la plantilla:

root@anibal:~# vzctl create 100 --ostemplate ubuntu-10.04-x86 --ipadd 10.0.0.100 --hostname equipo100
Creating VE private area (ubuntu-10.04-x86)
Performing postcreate actions
VE private area was created
Ahora deberemos configurar algunos aspectos de la máquina virtual, iniciarla y cambiarle la clave de root:
root@anibal:~# vzctl set 100 --nameserver 10.0.0.1 --save
Saved parameters for VE 100
root@anibal:~# vzctl set 100 --onboot yes --save
Saved parameters for VE 100
root@anibal:~# vzctl start 100
Starting VE ...
VE is mounted
Adding IP address(es): 10.0.0.100
Setting CPU units: 1000
Configure meminfo: 65536
Set hostname: equipo100
File resolv.conf was modified
VE start in progress...
root@anibal:~# vzctl exec 100 passwd
Enter new UNIX password: nuevaclave
Retype new UNIX password: nuevaclave
passwd: password updated successfully

Tras esto DEBEREMOS loguearnos usando ssh en la máquina remota para continuar nuestro trabajo: instalar los paquetes necesarios para poder trabajar en castellano. Recomiendo ENCARECIDAMENTE que el resto de trabajo se realice bajo una conexión SSH y no con el comando "vzctl enter 100" para que se aplique correctamente la configuración local al usuario.

root@anibal:~# ssh 10.0.0.100
The authenticity of host '10.0.0.100 (10.0.0.100)' can't be established.

Ahora, con los paquetes adecuados instalados sólo nos queda un único paso para tener en castellano nuestra ubuntu server: configurar la configuración local. Para ello tecleamos:

root@equipo100:~# update-locale LANG="es_ES.UTF-8" LANGUAGE="es_ES.UTF-8" LC_ALL="es_ES.UTF-8"

Antes de reiniciar nuestra máquina para comprobar que todo ha quedado bien procederemos a configurar la zona horaria:

root@equipo100:~# dpkg-reconfigure tzdata

Nos aparecerá un listado de contenientes en el que deberemos seleccionar "Europe":

Tras elegir Europa, deberemos seleccionar "Madrid" en el siguiente listado de localizaciones:

Tras configurar la zona horaria nos aparecerá la hora actual para confirmarnos que todo ha ido bien:

Current default time zone: 'Europe/Madrid'
Local time is now: Fri Jul 16 11:45:47 CEST 2010.
Universal Time is now: Fri Jul 16 09:45:47 UTC 2010.

Tras salir y entrar de nuevo a través de SSH veremos que todo (o casi todo) aparece en castellano. Podemos probar el resultado de un "apt-get update" o consultar una página del manual con "man ls" para comprobarlo:
