#!/bin/bash # Nightly backup system for home directories and MySQL # databases for websites managed by CPanel. # Author: Kieran O'Shea # Author's Website: www.kieranoshea.com # Support: kieran@kieranoshea.com # License: GPLv2 # USAGE: Place this file inside the directory you want to # put backups in, set it as a CRON job to run and collect # backups from the site(s) you define below at a preset # time each day, or run it manually everytime you want to # take a backup. You can place an unlimited number of sites # and databases to be backed up in the variables below so # long as you follow the convention. It doesn't even matter # if your different domains are hosted in different locations # so long as they are all managed by CPanel. # Prerequisites: # - Linux box with bash shell # - wget installed # Define all the sites you wish to backup in the array below # Domain name and tld only, eg. kieranoshea.com domain=( domain1.com domain2.com ) # Define all the usernames for the above sites in the array # below - keep order consistant! user=( user1 user2 ) # Define all the passwords for the above usernames in the # array below - keep order consistant! If you log on as # reseller or root you can enter the same password in # every array position, but none the less they must be filled. pass=( pass1 pass2 ) # Number of databases in each domain above - keep order # consistant. If you don't wish to backup any databases # for a particular domain, or don't have any for it, place # a 0 in it's position in the array. no_of_db=( 3 1 ) # Database names, exactly as they are in CPanel, in the order # that the domains appear. You may like to log into CPanel # manually and check your database names before filling this # variable in. Number of db names here must match the above # variables also! Eg. all dbs in domain 1 followed by all # dbs in domain 2 etc. You DO NOT need to enter any database # names below for a domain if you have placed a zero for it # in the array above databases=( domain1_datebase1 domain1_datebase2 domain1_datebase3 domain2_datebase1 ) # Thats all folks, save the file, CHMOD it to be executable # by the user who will run it, and you are all set. # Do not edit anything below this point! echo echo "-----------------------------------------------------------------" echo "Kieran's nightly backup system started" echo "-----------------------------------------------------------------" echo "" echo "-----------------------------------------------------------------" echo "Creating a directory in your backup path for tonights backup..." echo "-----------------------------------------------------------------" FOLDER="$(date +%d-%m-%Y)" mkdir $FOLDER cd $FOLDER echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "Creating a directory for every domain to be backed up into..." echo "-----------------------------------------------------------------" count=${#domain } i=0 while [ "$i" -lt "$count" ] do mkdir ${domain[$i]} let "i = $i + 1" done echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "Backing up MySQL databases..." echo "-----------------------------------------------------------------" overall_db_count=0 count=${#domain } i=0 while [ "$i" -lt "$count" ] do cd ${domain[$i]} mkdir databases cd databases start_point=$overall_db_count # start point for iterating over the array of db names let "end_point = $overall_db_count + ${no_of_db[$i]}" # end point to stop iterating (always the overall count!) n=$start_point while [ "$n" -lt "$end_point" ] do wget http://${user[$i]}:${pass[$i]}@www.${domain[$i]}:2082/getsqlbackup/${databases[$n]}.gz let "n = $n + 1" done let "overall_db_count = $overall_db_count + ${no_of_db[$i]}" # increase the overall count to keep a tally cd .. cd .. let "i = $i + 1" done echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "Backing up home directories; this make take some time..." echo "-----------------------------------------------------------------" count=${#domain } i=0 while [ "$i" -lt "$count" ] do cd ${domain[$i]} wget http://${user[$i]}:${pass[$i]}@www.${domain[$i]}:2082/getbackup/backup-${domain[$i]}-$FOLDER.tar.gz cd .. let "i = $i + 1" done echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "All backup tasks completed.

Update 2010-11: Configure PHP for User Directories. There have been more than a couple searches leading here that are similar to "configure PHP virtual hosts". There was a change to the default Apache config introduced in Ubuntu 10.4, Lucid Lynx. There is a message in the /etc/apache2/mods-available/php5.conf file that tells you what to do. REMEMBER: Restart apache and clear your browser's cache after the changes are made. A more detailed description is given at the Ubuntu User-Directory-PHP Wiki. Here is my copy with the (totally unprofessional) hack to get my ".file" files processed as PHP. <IfModule mod_php5.c>   AddHandler application/x-httpd-php .php .html .htm .file   <FilesMatch "\.ph(p3?|tml)$">     SetHandler application/x-httpd-php   </FilesMatch>   <FilesMatch "\.phps$">     SetHandler application/x-httpd-php-source   </FilesMatch>   # To re-enable php in user directories comment the following lines   # (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it   # prevents .htaccess files from disabling it.     #<IfModule mod_userdir.c>     # <Directory /home/*/public_html>     # php_admin_value engine Off     # </Directory>     #</IfModule> </IfModule>

Apache2: Virtual Hosts for Clients in Your Private LAN & PHP Configuration Go to the first page Apache2 public_html & Virtual Directories and read the disclaimer. Thanks.

Virtualización por S.O Virtualizar significa instalar un sistema operativo dentro de otro al que se le llama guest (invitado), mediante el uso de una máquina virtual. Frecuentemente denominada virtualización compartida del Sistema Operativo o virtualización del SO, la virtualización del Sistema Operativo virtualiza servidores en la capa del sistema operativo (kernel). Este método de virtualización crea particiones aisladas o entornos virtuales (VEs) en un único servidor físico e instancia de SO para así maximizar los esfuerzos de administración del hardware, software y centro de datos. La Virtualización de Hypervisor tiene una capa base (generalmente un kernel, Linux que se muestra aquí como un hypervisor o SO estándar) que se carga directamente en el servidor base. Para asignar hardware y recursos a las máquinas virtuales (VMs), es recomendable que todo el hardware del servidor esté virtualizado. La siguiente capa superior muestra cada chip, placa, etc. que debe virtualizarse para que así pueda ser asignado a las VMs. Una vez en la VM, hay un copia completa de un sistema operativo y finalmente la aplicación o carga de trabajo. La Virtualización de SO mejora el rendimiento, gestión y eficiencia. En la base reside un sistema operativo huésped estándar, en el caso de Parallels Virtuozzo que incluye Windows y Linux. A continuación encontramos la capa de virtualización, con un sistema de archivos propietario y una capa de abstracción de servicio de kernel que garantiza el aislamiento y seguridad de los recursos entre distintos contenedores. La capa de virtualización hace que cada uno de los contenedores aparezca como servidor autónomo. Finalmente, el contenedor aloja la aplicación o carga de trabajo.
