The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 2]

Version 1.0
Author: Falko Timme

This tutorial shows how to set up a Debian Lenny (Debian 5.0) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box).

I will use the following software:

  • Web Server: Apache 2.2.9 with PHP 5.2.6, Python, and Ruby
  • Database Server: MySQL 5.0.51a
  • Mail Server: Postfix
  • DNS Server: BIND9
  • FTP Server: proftpd
  • POP3/IMAP: I will use Maildir format and therefore install Courier-POP3/Courier-IMAP.
  • Webalizer for web site statistics

Please note that this setup does not work for ISPConfig 3! It is valid for ISPConfig 2 only!

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. 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 The Base System

Insert your Debian Lenny network installtion CD into your system and boot from it. Select Install (this will start the text installer - if you prefer a graphical installer, select Graphical install):

Choose your language:

Then select your location:

Choose a keyboard layout:

The installer checks the installation CD, your hardware, and configures the network with DHCP if there is a DHCP server in the network:

Enter the hostname. In this example, my system is called, so I enter server1:

Enter your domain name. In this example, this is

Now you have to partition your hard disk. For simplicity's sake I will create one big partition (with the mount point /) and a little swap partition so I select Guided - use entire disk (of course, the partitioning is totally up to you - if you like, you can create more than just one big partition, and you can also use LVM):

Select the disk that you want to partition:

Then select the partitioning scheme. As mentioned before, I select All files in one partition (recommended for new users) for simplicity's sake - it's up to your likings what you choose here:

When you're finished, select Finish partitioning and write changes to disk:

Select Yes when you're asked Write changes to disks?:

As usual, fantastic guide by Falko!
However, chose the extra partitions - /var, /tmp, /usr & /home
Got all the way to end of this guide, went to install ISPConfig & got this error from the installer package -

ERROR: Sie benötigen mind. 512MB Platz im /root-Verzeichnis, um ISPConfig zu installieren! / You need at least 512MB of disk space in the /root directory to install ISPConfig!

Therefore it seems you must be careful when partitioning if using ISPConfig 2. ISPConfig 3 had no problem with same partitioning.
