The Perfect Server - OEL 5.4 [ISPConfig 3]
Author: Josep Cols <josep [at] cols [dot] name>
This tutorial shows how to prepare a OEL 5.4 (Oracle Enterprise Linux) server for the installation of ISPConfig 3, and how to install ISPConfig 3 on a distributed configuration. OEL is a clone of RedHat ES, so, both are very similar. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, PureFTPd, SpamAssassin, ClamAV, and many more.
This installation shows how to install a distributed installation with:
A computer as database server.
Another computer as Webserver, Ftpserver and Webmail.
And a third computer as email server.
All this distributed configuration is monitored and managed by a unique and integrated ISPConfig 3 console.
Please note that this setup does not work for ISPConfig 2! It is valid for ISPConfig 3 only!
I do not issue any guarantee that this will work for you!
2 How to download the O.S. Software
3 How to install the base O.S.
4 Install Mysql
5 Install Webserver and Ftpserver
6 Install Email server
7 Install Squirrelmail Webmail
In order to do the complete installation, you need:
3 32 bits/Intel Computers, may be virtual ones, where to install the software. If you install on VMs and the VM does not allow to install a Linux OEL O.S., try to configure the VM as RedHat 5.4.
All of them will be configured on the same subnet and all must have access to the Internet to download sofware online.
For this tutorial we use the hostnames:
mysql.netbck.com with the IP address 192.168.1.211
http.netbck.com with the IP address 192.168.1.212
email.netbck.com with the IP address 192.168.1.213
The gateway 192.168.1.1
And the nameservers 18.104.22.168, 22.214.171.124
These settings might differ for you, so you have to replace them where appropriate.
User needed for the installation
All the installation must be made using the user root.
