Zimbra 6 on CentOS 5 Email and Calendars

Zimbra is a groupware system that provides email, calendaring, integrated antivirus and spam filtering, and more for multiple domains. Available in several editions, this guide will help you get the Open Source Edition installed on your CentOS 5

# yum install gmp compat-libstdc++-33 sysstat sudo libidn wget

Before proceeding, make sure your /etc/hosts file has valid entries. For reference, your file should resemble the following:
File: /etc/hosts
127.0.0.1     localhost.localdomain     localhost
10.30.56.8   mail.yeswedeal.com        mail

64 Bit OS
#wget http://files2.zimbra.com/downloads/6.0.8_GA/zcs-6.0.8_GA_2661.RHEL5_64.20100820052503.tgz

32 Bit OS
# wget http://files2.zimbra.com/downloads/6.0.8_GA/zcs-6.0.8_GA_2661.RHEL5.20100820051652.tgz

#tar -xzf zcs-6.0.8_GA_2661.RHEL5_64.20100820052503.tgz
#cd zcs-6.0.8_GA_2661.RHEL5_64.20100820052503
#./install.sh --platform-override
You appear to be installing packages on a platform different
than the platform for which they were built.

This platform is CentOS5
Packages found: RHEL5
This may or may not work.

Using packages for a platform in which they were not designed for
may result in an installation that is NOT usable. Your support
options may be limited if you choose to continue.


Install anyway? [N] Y 
 
You may receive a warning similar to the one shown below. Enter "Y" to proceed.
 
Before the install begins, you may receive a warning similar to the one shown below:
DNS ERROR resolving MX for archimedes.palegray.net It is suggested that the domain name have an MX record configured in DNS Change domain name? [Yes] No It is recommended (but not required) that the fully qualified domain name for your system (yeswedeal.com) have an MX record pointing to it. You may wish to visit your DNS control panel and add such a record now, or proceed if you won't be receiving mail for your FQDN on this system (for example, if you'll be receiving email for your base domain or others).
The install will continue, probably requiring a few minutes to perform various tasks. You'll be asked which components of the Zimbra package you'd like to install. For the purposes of this tutorial, choose the default values for each ("Y" or "N" depending on which letter is in the brackets).
Once the installation has completed, you'll be presented with an admin menu next.

Select, or 'r' for previous menu [r] 4 
 

You can configure various options here; but, the most important option is the one for
setting the administrator password. Enter "4" to set it, choosing a strong password
comprised of letters, numbers, and non-alphanumeric characters. After setting the
admin password, enter "r" to return to the main menu. You will be asked to apply the
new configuration. Type "a" and press enter. You may then allow the
program to proceed with the remaining installation steps.
After installation has completed, you'll need to start zimbra with the following command:

#service zimbra start
To have Zimbra start on every boot, enter the following command:

#chkconfig zimbra on

you may wish to reboot your Linode to make sure everything comes back up properly. After doing so, visit the Zimbra admin URL in your browser. It will be in the form https://yeswedeal.com:7071/. You'll need to accept the SSL certificate presented to access the admin panel, which you may then use to continue configuring your new Zimbra server. Enjoy!
