Zimbra Collaboration Suite (ZCS) Open Source Edition v5.0 On Debian Etch

Version 1.0
Author: Oliver Meyer

This document describes how to set up the Zimbra Collaboration Suite (ZCS) Open Source Edition v5.0 on Debian Etch. The resulting system provides a full featured collaboration-suite with many features that I can’t list all here - please have a look at the feature list. It also comes with a nice (themeable) AJAX web interface for administration and user access.

This howto is a practical guide without any warranty - it doesn’t cover the theoretical backgrounds. There are many ways to set up such a system - this is the way I chose.

1 Preparation

Install a standard Debian Etch system and update it. I used a network installation (only standard system).

2 Hostname

You have to assign the hostname to the server ip. It is very important that the fqdn entry appears before the hostname.

vi /etc/hosts

It should look like this:

127.0.0.1       localhost.localdomain localhost
192.168.0.110   server1.example.com server1

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Afterwards insert the hostname into the hostname file …

echo server1.example.com > /etc/hostname

… and reboot the system.

reboot

When the system is up again, the output of the both commands …

hostname

… and …

hostname -f

… should be:

server1.example.com

3 DNS

You need a running DNS server in your LAN that contains a valid A & MX record for this server - otherwise Zimbra won’t work. I used another server (192.168.0.100) running mydns for this howto. Add the nameserver’s IP to the resolve configuration:

vi /etc/resolv.conf

The nameserver on your LAN has to be the first entry. It should look like this:

nameserver 192.168.0.100
nameserver 192.168.0.2

4 Exim

Deinstall Exim - Zimbra comes with it’s own mailserver.

apt-get remove --purge exim4 exim4-base exim4-config exim4-daemon-light

5 Needed packages

Let’s install some needed packages (maybe some of these packages are already installed on your system).

apt-get install libc6-i686 sudo libidn11 curl fetchmail libgmp3c2 libexpat1 libgetopt-mixed-perl libxml2 libstdc++6 libpcre3 libltdl3 ssh
