Zimbra™ Collaboration Suite Single Server Installation Network Edition

Zimbra™ Collaboration Suite Single Server Installation Network Edition
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.
This guide includes the following sections:
Important Notice About Single Server Installations
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.
Note: A Zimbra license is required in order to create accounts on the Network Edition Zimbra Collaboration Suite server. You cannot install ZCS without a license. See "Zimbra License Requirements for ZCS Network Edition” .
The following ports are set as defaults when the Zimbra Collaboration Suite is installed.
 
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.
Installation Prerequisites
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.
System Requirements

Modifying Operating System Configurations
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.
Installation Modifications for Red Hat® Enterprise Linux®
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.
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 fully qualified 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: You will need to disable Sendmail in order to run the Zimbra Collaboration Suite. You can disable the Sendmail service with these commands: chkconfig sendmail off, service sendmail stop.
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.
 
127.0.0.1           localhost.localdomain localhost
your.ip.address         FQDN yourhostname
Installation Modifications for Fedora™
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.
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 name [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 application. The Sendmail command to stop the service is /etc/init.d/sendmail stop. To disable is chkconfig sendmail off. The Postfix command to stop the service is /etc/init.d/postfix stop. To disable is chkconfig postfix stop.
Make sure that 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
 
Installation Modifications for Mac OS® Servers
No modifications are required for Mac OS servers, but Java 1.5 must be set as the default Java.
To set Java 1.5 as the default:
Configure DNS
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.
Note: Even if a relay host is configured, an MX record is still required if the ZCS server is going to receive email from the Internet.
Overview of Installation Process
When you run the install script, the Zimbra install verifies that the correct prerequisite packages are installed.
Zimbra Core installs the libraries, utilities, and monitoring tools.
Zimbra LDAP installs the OpenLDAP software, which provides 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.example.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.
Zimbra License Requirements for ZCS Network Edition
A Zimbra license is required in order to create accounts in the Network Edition Zimbra Collaboration Suite servers.
A trial license and a regular license are available:
Trial. You can obtain the trial license from the Zimbra license portal for free. The trial license allows you to create up to 50 users. It expires in 60 days.
Regular. You must purchase the Zimbra Regular license. This license is valid for a specific Zimbra Collaboration Suite system and is encrypted with the number of Zimbra accounts (seats) you have purchased, the effective date, and expiration date of the regular license.
Go to Zimbra’s Website to obtain a trial license from the Network Downloads area. Contact Zimbra sales to purchase a regular license, by emailing sales@zimbra.com or calling 1-650-212-7767, extension 100.
The regular license can only be installed on the ZCS system for which it is purchased. Only one Zimbra license is required for your Zimbra Collaboration Suite environment.
The license file must be on your server before you start the installation. You add the license file during the ZCS installation.
Current license information, including the number of accounts purchased, the number of accounts used, and the expiration date, can be viewed from Global Settings>License tab on the administration console.
Basic Configuration
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.
The table below describes the menu options
The host name configured in the Red Hat operating system installation
The LDAP host name. On a single server installation this name is the same as the hostname.
The root LDAP password for the host. This password is automatically generated.
Create Domain — Yes. You can create one domain during installation and additional domains can be created from the administration console.
Domain to create — The default domain is the fully qualified hostname of the server. If you created a valid mail domain on your DNS server, enter it now. In most cases, you will accept the default.
Create Admin User — The administrator account is created during installation. This account is the first account provisioned on the Zimbra server and allows you to log on to the administration console.
Admin user to create — The default is admin@[mailhost.example.com].
Admin Password — You must set the admin account password. The password is case sensitive and must be a minimum of six characters. The administrator name, mail address, and password are required to log in to the administration console.
