Installation Modifications for Red Hat Enterprise Linux

The Zimbra Collaboration Suite runs on the Red Hat Enterprise Linux,AS/AE 4 or 5 operating system. When you install the Red Hat software for the Zimbra Collaboration Suite, accept the default setup answers to install the minimum configuration, except for the following steps that must be modified.

Refer to the Red Hat Enterprise Linux installation guide for detailed documentation about installing their software.

•	Disk Partitioning Setup. Check Manually partition with DiskDruid. The disk partition should be set up as follows:

•	The Mount Point/RAID Volume size for the /boot partition should be 100 MB.

•	The Swap partition should be set to twice the size of the RAM on your machine.

•	The Root partition (/) should be set with the remaining disk space size.

 

•	Network Configuration>Network Devices>Hostname should be configured manually with the hostname [mailhost.example.com] of the Zimbra server.

 

•	Enter the Gateway and Primary DNS addresses.

•	In the Edit Interface pop-up screen, check Activate on Boot. Enter the IP Address and Netmask of the device. This allows the interface to start when you boot.

•	Firewall Configuration should be set to No firewall, and the Security Enhanced Linux (SELinux) should be disabled.

Important: The following should also be considered before you install the Zimbra Collaboration Suite.

•	You must disable Sendmail in order to run the Zimbra Collaboration Suite. Disable the Sendmail service with these commands, chkconfig sendmail off, service sendmail stop.

•	A fully qualified domain name is required. Make sure that the FQDN entry in /etc/hosts appear before the hostnames. If this is missing, the creation of the Zimbra certificate fails. The FQDN entry should look like this example.

 

127.0.0.1          localhost.localdomain localhost your.ip.address        FQDN yourhostname
