This tutorial shows how to prepare a CentOS 6.2 x86_64 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, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache; this tutorial covers the setup of a server that uses Apache, not nginx.

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:


2 Preliminary Note

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


3 Install The Base System

Boot from your first CentOS 6.2 DVD (DVD 1). Select Install or upgrade an existing system:

It can take a long time to test the installation media so we skip this test here:

The welcome screen of the CentOS installer appears. Click on Next:

Choose your language next:

Select your keyboard layout:

I assume that you use a locally attached hard drive, so you should select Basic Storage Devices here:

You might see the following warning - Storage Device Warning. If you see this click on the Yes, discard any data button to proceed:

Fill in the hostname of the server (e.g., then click on the Configure Network button:

Go to the Wired tab, select the network interface (probably eth0) and click on Edit...:

Mark the Connect automatically checkbox and go to the IPv4 Settings tab and select Manual in the Method drop-down menu. Fill in one, two, or three nameservers (separated by comma) in the DNS servers field (e.g.,, then click on the Add button next to the Addresses area:

Now give your network card a static IP address and netmask (in this tutorial I'm using the IP address and netmask for demonstration purposes; if you are not sure about the right values, might help you). Also fill in your gateway (e.g. and click on the Apply... button:

The network configuration is now finished. Click on the Next button:

I'm trying to use your tutorial, but there are a lot of diferences between what I read here and what I found into CentOS 6.2

 For example, I don't have anymore system-config-* command files :(

From: Deunan Knute at: 2012-02-01 04:49:14

You may need to separately install them, if you chose Minimal Install

Try this -

yum install system-config-network-tui system-config-firewall-tui

YES..... Very important step..... thanks for this tip :)

Great tutorial, just migrated from cPanel and Apache and I am very happy with the performance and financial savings. I had the issue with courier-imap install but building from source fixed that.

Would be great to have this as a script with minimal user input but i dont have the knowledge to do it

I did a fresh install and when trying to access ISPconfig I'm just getting a White Screen.

Would that have to do with PHP 5.3.3?

I am installing a fresh CentOS 6.3 instead of 6.2 following this guide.   The order of installation windows is a bit different for a 6.3 install than 6.2 but most of the information in the steps still apply.  Here is one big difference which gave me tons of frustration on my previous 6.3 install following this guide that I have discovered an easy solution during installation for:

Where the guide says:

"Next we do the partitioning. Select Replace Existing Linux System(s). This will give you a small /boot partition and a large / partition which is fine for our purposes:"

Problem: This isn't true in 6.3, instead, this will give you a large /home partition and a small / partition and a very small /boot partition.  The problem is that for a server we want a large / partition (technically a large /var partition but I just like to make the whole / partition large because its quick & easy)

Solution: Make sure you check the box on the bottom: "Review and modify partitioning layout" before clicking next.  On the next screen, simply swap the size on the / and the /home partitions and you're all set. Make sure to set the /home partition to the / partition size first to free up the resources.

Important: If you don't do this now then you will need to boot from the OS disk later in order to modify the / partition, so best to do it now and save yourself the hassle of running out of room in your /var/www folder later.

If you're like me and completely missed the button to setup your network when setting your server host name during installation, then there are some additional steps to take that may save you some time that I learned the hard way.  I'm installing CentOS 6.3 by the way:

Problem: Even after using system-config-network, the eth0 card won't automatically connect nor will it be set to automatically connect on boot unless you've set these options during install.

Solution:  First use system-config-network as described in the guide to set both the Device Configuration and the DNS Configuration.  After that use the command:

vi /etc/sysconfig/network-scripts/ifcfg-eth0

and update the following settings:


Then do a:


Then run a:


and all should be well to continue with the guide!   Cheers to us button skippers!

This installs the 2.11 version of phpMyAdmin. 'yum install phpMyAdmin' will grab one from the 3.4 branch, but it's still outdated a bit. I'd recommend getting the latest 3.4 version from and install from source.

From: Anonymous at: 2012-03-27 00:32:27

Looks like it grabs 3.4.9-1 now, however in the step

vi /etc/httpd/conf.d/phpmyadmin.conf 

You now have to put in vi /etc/httpd/conf.d/phpMyAdmin.conf and the next step it changed to vi /usr/share/phpMyAdmin/

Make sure install EPEL Packet.  Install the EPEL package using the command below.

rpm -Uvh

It's work for me.

Check repository settings. Make sure you install from below repositories:

Great tutorial!
Even this linux nono did it with this great tutorial.


From: Anonymous at: 2012-07-07 09:29:37

I agree I have never used any form of linux before and was a great set of instructions!
very well put together tutorial.
also learned a lot during the install.

Would be great if anyone knows of a tutorial or guide to fully secure and lock down the server after the install, remove vunralbilities etc...

Great work

From: daro at: 2012-10-10 11:27:20

The best ever tutorial online. I start to prefer Linux Command Lines after this Great Tutorial; and I will never go to automatic applications such as Webmin and Virtualmin which produce lots of bugs causing me to be stuck with them for two weeks until I found this brilliant perfect VPS server. I am at the final stage of Squirrelmail configuration, and seems to be working fine at moment. Cheers

From: IPVS at: 2012-12-14 01:56:24

I'm baffled.. I spent 3 hours installing IPSConfig3.  It went perfect.    It then installed ISPConfig , noted Installation Completed.   And within 5 seconds, the system went dead.   I couldn't ping it... Nothing.   I powered the system off, then powered it back on maintaining a ping to it... As soon as it was ping-able, I ssh'ed into it... and it went completely dead again within 5 seconds... ????

See the ouptut for the last part of the install...  I'm completely baffled on where to go from here???

This is the best tutorial I've ever discovered! Thank you so much!    I had only 2 issues during the process:

 1.) service named start

This hung for several minutes so I spent about 2 hours trying to debug.  Bind requires using /dev/random to create a key the first time its run, which can take a very long time depending on your system.  Just let it run until its done, it will eventually finish.


2.) I installed mailman exactly as the tutorial says, and used wget to install ISPConfig 3, however, mailman wasn't detected during the install php script.   Not a big deal for me for now I guess, but I'm not sure what happened.
