The Zimbra Collaboration Suite includes the Zimbra MTA, the Zimbra LDAP server, and the Zimbra mailbox server. In a single-server installation, all components are installed on one server and require no additional manual configuration.
This installation guide is a quick start guide that describes the basic steps needed to install and configure the Zimbra Collaboration Suite in a direct network connect environment. In this environment, the Zimbra server is assigned a domain for which it receives mail, and a direct network connection to the Internet. When the Zimbra Collaboration Suite is installed, you will be able to log on to the Zimbra administration console to manage the domain and provision accounts. The accounts you create will be able to send and receive external email.
The Zimbra Collaboration Suite is designed to be the only application suite installed on the server. The Zimbra Collaboration Suite bundles and installs, as part of the installation process various other third party and open source software, including Apache Tomcat, Postfix, OpenLDAP®, and MySQL®. The versions installed have been tested and configured to work with the Zimbra software. See the
Administration Guide for a complete list of software.
Important: You cannot have any other web server, database, LDAP, or MTA server running, when you install the Zimbra software. If you have installed any of the applications, before you install Zimbra software, disable these applications. During the ZCS install, Zimbra makes global system changes that may break applications that are on your server.
In order to successfully install and run the Zimbra Collaboration Suite, ensure your system meets the requirements described in this section. System administrators should be familiar with installing and managing email systems.
Note: To find SSH client software, go to Download.com at http://www.download.com/ and search for SSH. The list displays software that can be purchased or downloaded for free. An example of a free SSH client software is PuTTY, a software implementation of SSH for Win32 and Unix platforms. To download a copy go to
http:// putty.nl/.
Configuration modifications for two of the most frequently used operating systems, Red Hat Enterprise Linux and Fedora, are described in this guide. The SUSE configuration would be similar to those described for the Red Hat Enterprise Linux. The Mac OS requires no additional modifications.
Other operating systems may require similar modifications, use this information as a reference to gauge whether your operating system may need to be modified. Also, search the
Zimbra Forums and
Zimbra Wiki.
The Zimbra Collaboration Suite runs on the Red Hat Enterprise Linux, version 4 operating system. When you install the Red Hat software for the Zimbra Collaboration Suite, accept the default setup answers, except for the Disk Partition Setup, the Network Configuration, the Gateway and Primary DNS addresses, the Edit Interface, and the Firewall Configuration. Details of what should be modified in these categories are listed below. Refer to the Red Hat Enterprise Linux installation guide for detailed documentation about installing their software.

•
|
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.
|
|
•
|
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: Make sure that FQDN entry in /etc/hosts appears before the hostnames. If this is missing, the creation of the Zimbra certificate fails. The FQDN entry should look like this example. See
zmcreatecert in the
Administrator’s Guide, Appendix A: Command-Line Utilities.
The Zimbra Collaboration Suite runs on the Fedora, Core 4 operating system. When you install the Fedora software for the Zimbra Collaboration Suite, accept the default setup answers, except for the Disk Partition Setup, the Network Configuration, the Gateway and Primary DNS addresses, the Edit Interface, and the Firewall Configuration. Details of what should be modified in these categories are listed below. Refer to the Fedora installation guide for detailed documentation about installing their software.

In order to send and receive email, the Zimbra MTA must be configured in DNS with both A and MX records. For sending mail, the MTA uses DNS to resolve hostnames and email-routing information. To receive mail the MX record must be configured correctly to route the message to the mail server.
During the installation process ZCS checks to see if you have an MX record correctly configured. If it is not, an error is displayed suggesting that the domain name have an MX record configured in DNS.
You must configure a relay host if you do not enable DNS. After ZCS is installed, go to the
Global Settings>MTA tab on the administration console and uncheck
Enable DNS lookups. Enter the relay MTA address to use for external delivery.

Zimbra developed different applications to facilitate moving a user’s email messages, calendars, and contacts from their old email servers to their accounts on the Zimbra server. When the user’s files are imported, the folder hierarchy is maintained. Use one of the ZCS utilities to move user mail to ZCS to guarantee that all information is imported correctly.
The following applications can be accessed from the administration console Download page, and instruction guides are available from the Help Desk page or from the Zimbra Website, Documents page.
