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.
• Zimbra Store installs the mailbox server, including Apache Tomcat, the servlet container for the Zimbra server.
• Zimbra Spell installs the Aspell open source spelling checker. When Zimbra spell is installed, Zimbra-Apache is also installed.
• Zimbra SNMP installs the SNMP package for monitoring. This package is optional.
• Zimbra Logger installs tools for syslog aggregation, reporting, and message tracing.
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.
Downloading the Zimbra Software
For the latest Zimbra software download, go to www.Zimbra.com. Save the Zimbra Collaboration Suite archive file to the computer from which you will install the software.
When the Zimbra Collaboration Suite is installed, the following Zimbra applications are saved to the Zimbra server:
• Zimbra Collaboration Suite Connector for Outlook® (ZCS Network Edition only). Format is a .msi file. This is a MAPI service provider that is installed on users’ computers.
• Zimbra Collaboration Suite Migration Wizard for Exchange. Format is .exe file. Users can be migrated from Microsoft® Exchange server email accounts to Zimbra server accounts.
• Zimbra Collaboration Suite Import Wizard for Outlook. Format is an .exe file. Users can import their Outlook .pst files to the Zimbra server.
• ZCS documents, including administrator’s guide, installation guides, Migration Wizard guide, and release notes.
See the Administrator’s Guide for information about the ZCS Connector for Outlook and the PST Import Wizard. See the Migration Wizard Guide for information about the Migration Wizard file.
The default configuration installs the Zimbra-LDAP, the Zimbra-MTA with anti-virus and anti-spam protection, the Zimbra mailbox server, the SNMP monitoring tools (optional), Zimbra-spell (optional), and the logger tool (optional), on one server.
The menu driven installation displays the components and their existing default values. During the installation process you can modify the information.

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
