How to Install RoundCube on CPanel

The First step is to remove the previous traces of Roundcube in the server.
cd /usr/local/cpanel/base
rm -rf roundcube*
mysql
mysql>drop database roundcube;

Before starting the installation, you need to know the root password of Mysql.
Lets proceed….
cd /usr/local/cpanel/base
wget http://easynews.dl.sourceforge.net/sourceforge/roundcubemail/roundcubemail-0.1beta2.1.tar.gz
tar -zxvf roundcubemail-0.1beta2.1.tar.gz
mv -f roundcubemail-0.1beta2 roundcube
cd roundcube
chmod -R 777 temp
chmod -R 777 logs

Create the database. Find mysql root password from /root/.my.cnf.
Login as user, root.
mysql -u root -p
Password:
mysql>CREATE DATABASE roundcube;
mysql>use roundcube;
mysql>source SQL/mysql.initial.sql;
mysql>quit

Add the configuration:
cd config
mv db.inc.php.dist db.inc.php
mv main.inc.php.dist main.inc.php

Edit the configuration files

====================
using your text editor edit db.inc.php

Find:
$rcmail_config['db_dsnw'] = ‘mysql://roundcube:pass@localhost/roundcubemail’;
Replace with:
$rcmail_config['db_dsnw'] = ‘mysql://root:rootpass@localhost/roundcube’;
#vi main.inc.php
====================
Replace the corresponding root password

====================
using your text editor edit main.inc.php
Find:
$rcmail_config['default_host'] = ”;
Replace with:
$rcmail_config['default_host'] = ‘localhost’;
====================

Configure cPanel to show roundcube in the theme. X theme(default) only!!
cd /usr/local/cpanel/base/roundcube/skins/default/images/
cp roundcube_logo.png /usr/local/cpanel/base/frontend/x/images/roundcube_logo.png
cp roundcube_logo.png /usr/local/cpanel/base/webmail/x/images/roundcube_logo.png
wget http://www.yourserverguide.com/Files/HGpatch-roundcube-1.0BETA2.1
patch -p0 < HGpatch-roundcube-1.0BETA2.1

If you receive a message stating: Reversed (or previously applied) patch detected! Assume -R? Please press N for No as this is because you previously installed roundcube

This will auto do all the necessary changes to roundcube and the X theme. Once the patch is executed you may now access roundcube via http://yourdomain/webmail
