When you run the install script then Zimbra installation verifies that the correct prerequisite packages are installed.
• Zimbra Core installs the libraries, utilities, and monitoring tools.
• Zimbra LDAP installs the OpenLDAP software, an open source LDAP directory services.
• Zimbra MTA installs the Postfix open source MTA, the Clam AntiVirus antivirus engine, the SpamAssassin junk mail filter, and the Amavisd-New content filter.

The Zimbra server configuration is menu driven. The installation menu shows you the default configuration values. The menu displays the logical host name and email domain name [mailhost.knowledgelinux.com] as configured on the computer. You can change any of the values. For single server installs, the only value you must define is the administrator’s password. The password is used to log on to the Zimbra administration console.

Installing Zimbra Software
For servers other than Mac servers, open an SSH session to the Zimbra server and follow the steps below.
For Macs, see “Installing Zimbra Software on a Mac Server” .
1. Log in as root to the Zimbra server and cd to the directory where the Zimbra Collaboration Suite archive tar file is saved (cd /var/<tmp>). Type the following commands.
• tar xzvf [zcs.tgz], to unpack the file
• cd zcs, to change to the correct directory
• ./install.sh, to begin the installation
The install.sh script reviews the installation software to verify that the Zimbra packages are available.
The screen shots are examples of the Zimbra installation script

[root@mailhost. tmp]# tar xzvf zcs.tgz
[root@mailhost tmp]# cd zcs
[root@mailhost zcs]# ./install.sh
