Well, it would be a quick note. I’ve successfully installing Zimbra 5.0.21 on openSUSE 11.1 and openSUSE 11.2 32 bit and also Zimbra 6.0.3 on openSUSE 11.1 and openSUSE 11.2 64 bit (Currently testing Zimbra 6.0.4 on openSUSE 11.1 & openSUSE 11.2 64 bit). I’ll be write another quick note after completing this one :
PREPARATION & BASE INSTALLATION SETUP :
- Install openSUSE 11.2. I’m using openSUSE 11.2 DVD installation and choose to install a Text mode (server installation mode) to prevent any unused service to be installed. Please remember to give the /opt or / partition more than 5 GB (Recommended : > 10 GB) for minimal installation. a Raid-1 partition model would be a good option for production use. Also, don’t forget to setting up your time zone for correct setting of server date & time.

New installation using Automatic Configuration 
Setting up Time Zone 
Choosing Minimal Server (Text Mode) on Installation option to prevent/remove any unused service for mail server 
Edit/Resize partition image. Zimbra need minimum 5GB of /opt folder size 
I used only 2 partition (/ and swap) and used almost full harddisk to root partition, only as testing model on my virtual image. Just adapts it with your requirement. 
Create standard user for daily purpose. Automatic login will be disabled by default for text mode installation 🙂 
Overview of base installation. I will using standard option and will make any changes & add any requirement library later. 
Final Installation Confirmation. No way back 🙂 
First initial login after completing the base installation. Click for higher image. - Disable unused software repositories. Go to YAST | Software | Software Repositories and disable unused repos. Keep the repositories would be used for next package installation. You could also disabling repositories using zypper (zypper mr -d NumberofRepo)
- Disable firewall service for temporary installation. We could re-activating the firewall (and it should be 🙂 ) later. Go to YAST | Security & Firewall | Firewall and disable the service. Don’t forget to click the option “Stop Firewall Now”.
- Edit the IP Address, Name Server and Routing Gateway to meet with our requirement. In my case, I will install the DNS Server so my first name server will be my own IP (Zimbra IP). Goto YAST | Network Device | Network Settings and take a look at screenshot.
- Move to Global Options tab. Mark “Enable IPv6” unchecked if you do not use IPv6 support or vice versa, leave it checked if you wish to support IPv6
- Move to Overview. Edit and pick a static IP Address. Give a subnet mask and leave host name empty. Since openSUSE 11.x supporting a simple and longer subnet mask, you could give the subnet mask as 255.255.255.0 or just /24 instead. Off course, you should adjust the setting with your environment.
Setting UP IP Address & Subnet mask - Click Next and then move to Hostname & DNS tab. Setup your hostname (eg : mail), your domain, Name Server 1,2 and 3 and domain search. Please remember that I will make a local DNS Server so pick the Zimbra IP as Name server 1. I take Name server 2 and name server 3 for my ADSL modems IP (modem DNS service) and ISP/public DNS
Setting Up Hostname & DNS - Move to Routing tab and write your routing IP at Default IPv4 Gateway option. Keep the Default IPv6 Gateway option as empty unless you weren’t disabling IPv6 support on Global Options tab.
Setting up routing & gateway - Click OK
- Edit /etc/hosts file and add/change your setting as below
Setting up hostname & DNS
