This tutorial shows how to prepare a CentOS 5.2 server for the installation of ISPConfig 3, and how to install ISPConfig 3. 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,MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.
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!
 

1 Requirements

To install such a system you will need the following:
• Download the CentOS 5.2 DVD or the six CentOS 5.2 CDs from a mirror next to you (the list ofmirrors can be found here: http://isoredirect.centos.org/centos/5/isos/i386/).
• a fast Internet connection.
 

2 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100 and the gateway 192.168.0.1. These settings might differ for you, so you have to replace them where appropriate.
 

3 Install The Base System

Boot from your firstCentOS 5.2 CD (CD 1) or the CentOS 5.2 DVD. Press at the boot prompt:

I'm installing CentOS 5.2 on a fresh system, so I answer Yes to the question Would you like to initialize this drive, erasing ALL DATA?

Now we must select a partitioning scheme for our installation. For simplicity's sake I select Remove linux partitions on selecteddrives and create default layout. This will result in a small /boot and a large / partition as well as a swap partition. Of course, you're free to partition your hard drive however you like it. Then I hit Next:

On to the network settings. The default setting here is to configure the network interfaces with DHCP, but we are installing a server, so static IP addresses are not a bad idea... Click on the Edit button at the top right.

In the window that pops up uncheck Use dynamic IP configuration (DHCP) and Enable IPv6 support and give your network card a static IP address (in this tutorial I'm using the IP address 192.168.0.100 for demonstration purposes) and a suitable netmask (e.g. 255.255.255.0; if you are not sure about the right values, http://www.subnetmask.info might help you):

Set the hostname manually, e.g. server1.example.com, and enter a gateway (e.g. 192.168.0.1) and up to two DNS servers (e.g. 213.191.92.86 and 145.253.2.75):
