In our previous article we performed the Single Server Installation of Zimbra Collaboration Suite, so in this article we will guide you through the detailed steps to deploy Zimbra Collaboration 8.6 Suite in Multi Tenancy environment that will comprises of 3 separate servers where the installation will be done one by one using the same installation script on each server. We will select the particular components to install and use the menu as per our requirements to configure the system.
Servers Installation Order
Install and configure Zimbra servers in the following order:
- LDAP server
- Zimbra Mailbox server
- Zimbra MTA server
Zimbra Multiservers Basic Setup
1) Installation of Zimbra LDAP Server
Let’s start with the basic parameters to configure Zimbra LDAP server and make sure that the firewall is disabled, FQDN hostname and IP address assigned to the host.
Zimbra LDAP server must be configured before the other servers to provide user authentication through OpenLDAP.
Zimbra LDAP server must be configured before the other servers to provide user authentication through OpenLDAP.
Step 1: Login as a root on ZIMBRA-LDAP.
Step 2: Enter the fully qualified domain name in host file
# vim /etc/hosts
172.25.10.175 zimbra-ldap.linoxide.com zimbra-ldap
Step 3: Create a backup directory and place the ZCS source file in /backup directory.
[root@zimbra-ldap backup]# wget https://files.zimbra.com/downloads/8.6.0_GA/zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz
Step 4: Change directory to /backup directory.
#cd /backup
Step 5: Extract " zxvf zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz " in same directory.
[root@zimbra-ldap backup]# ls
zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz
[root@zimbra-ldap backup]# tar zxvf zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz
Step 6: Change directory to zcs-8.6.0_GA_1153.RHEL7_64.20141215151110
[root@zimbra-ldap backup]# cd zcs-8.6.0_GA_1153.RHEL7_64.20141215151110
[root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]#
Step 7: Start the setup and make sure that all prerequisites libraries are installed .
# ./install.sh --platform-override

Once all the ldap configurations are made type "x" to view all the changes that we made here and press "a" to apply these changes. Press "Y" to confirm system modifications.
Impliment Comfigurations
After confirmation of all configured settings, it will ask to notify zimbra about the installation. Choose "Y/N" to proceed with LDAP server configurations.
Common Steps to Run Servers Properly
Once installation is done, do the common following steps on each server to fucntion properly.
Step 1: Restart and Enable crond service
Step 1: Restart and Enable crond service
[root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]# systemctl restart crond
[root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]# systemctl enable crond
Step 2: Open rsyslog.conf file and uncomment following two lines
[root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]# vim /etc/rsyslog.conf
$ModLoad imudp
$UDPServerRun 514
Step 3: Restart and Enable rsyslog service
[root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]# systemctl restart rsyslog
[root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]# systemctl enable rsyslog
Step 4: Now run the below command to update rsyslog
root@zimbra-ldap zcs-8.6.0_GA_1153.RHEL7_64.20141215151110]# /opt/zimbra/libexec/zmsyslogsetup
updateSyslog: Updating /etc/rsyslog.conf...done.
Zimbra Services Check
Now switch user to zimbra and check the status of zimbra services as:

Zimbra Administration Home
From zimbra administration console we are now able to manage and create new domains and users.
Zimbra Servers Status
Zimbra Servers status shows the availability of each service installed on the servers.
Congratualations! we had successfully configured the fully functional zimbra email server in a multi-tenancy environment for the best performance and results for your organisational and personal email services. Now enjoy with each Zimbra mailbox which is secured and protected, with included anti-virus, anti-spam, and daily mailbox-level backups and accessible from anywhere, anytime to access your email accounts with Zimbra Desktop, Microsoft Outlook mobile email support, and Web-based email portal.
