The Perfect Setup - Debian Sarge (3.1)
Author: Falko Timme
This is a detailed description about the steps to be taken to setup a Debian based server (Debian Sarge alias Debian 3.1) that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/POP3s/IMAP/IMAPs, Quota, Firewall, etc.).
I will use the following software:
- Web Server: Apache 2.0.x
- Mail Server: Postfix (easier to configure than sendmail; has a shorter history of security holes than sendmail)
- DNS Server: BIND9
- FTP Server: proftpd
- POP3/POP3s/IMAP/IMAPs: in this example you can choose between the traditional UNIX mailbox format (we then use ipopd/uw-imapd) or the Maildir format (in this case we will use Courier-POP3/Courier-IMAP).
- Webalizer for web site statistics
In the end you should have a system that works reliably and is ready for the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).
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!
To install such a system you will need the following:
- A Debian Sarge Netinstall CD (available here: http://ftp.de.debian.org/debian-cd/3.1_r0a/i386/iso-cd/debian-31r0a-i386-netinst.iso)
- an internet connection since I will describe a network installation in this document
1 The Base System
Insert your Sarge Netinstall CD into your system and boot from it (enter linux26 at the boot prompt to install a 2.6 kernel). The installation starts, and first you have to choose your language:
Select your country:
Choose a keyboard layout:
The hardware detection starts:
Enter the hostname. In this example, my system is called server1.example.com, so I enter server1:
Enter your domain name. In this example, this is example.com:
Now you have to partition your hard disk. I will create one big partition (with the mount point /) and a little swap partition:
