How to install Zimbra mail server on CentOS 7

How to install Zimbra mail server on CentOS 7

Introduction

What is a Zimbra Mail Server?

Communication is a crucial element in the setup of an organization, as we know, most communications occur via mail. Zimbra is therefore a leading open source email platform that manages all the contents in a mailbox. Such contents include messages, attachments, calendars, and contacts.  

One good thing about Zimbra is that each Zimbra mailbox server in a system is only bound to see its own storage volumes, it cannot read, write or see any other Zimbra server content.

Some of the OS that supports Zimbra mail servers include Red Hat enterprise, oracle Linux, CentOS Linux, and Ubuntu LTS server edition.

However, in this tutorial, we are going to learn how to install the Zimbra mail server on centOS 7.

Prerequisites for Zimbra Mail Server

For you to be able to install the Zimbra mail server, you will need a number of requirements which include;

  • 8 GB RAM (minimum of 3GB)
  • CentOS 7
  • 4 CPUs
  • 50GB free space
  • An A and MX record for your server
  • A fully qualified domain name (FQDN)

Right away, let’s embark on installing the Zimbra mail server on CentOS.

Step 1: Update CentOS

You have to log in to the CentOS server and make sure centOS is fully updated by running the following command, make sure to be logged in as root.

$ yum update –y

The next thing is to set up your server’s hostname, for our case we are going to use mail.techies.com.

hostnamectl set-hostname mail.techiescode.com
$exec bash

Now, the following lines need to be added to the /etc/hosts file

$ nano /etc/hosts

192.213.0.12 mail.techiescode.com
127.0.0.1 localhost  localhost localhost.localdomain localhost4 localhost$
::1         localhost localhost.localdomain localhost6 localhost6.localdo$

Using the dig command, you should now verify the A and MX records.

If you encounter an error saying dig command not found, install it with the following command;

$ sudo yum install bind-utils

Now proceed on verifying A and MX; 

[root@mail ~] dig -t A mail.techies.com
[root@mail ~] dig -t MX mail.techies.com

Step 2: Install prerequisites

First, you have to put into consideration that two mail servers can not run at the same time on one system, we should therefore remove postfix.

First, let’s check if it’s running.

$ service postfix status

We should therefore disable it;

 $ service postfix stop && chkconfig postfix off
Redirecting to /bin/systemctl status postfix.service
 postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/usr/lib/systemd/system/postfix.service; disabled; vendor preset: disabled)
Active: inactive (dead)

Postfix is disabled.

To install Zimbra, there are a number of prerequisites that need to be installed. Lucky enough, we can perform the task with a single command.

$ yum install -y gmp libidn wget nano make nc sudo sysstat libtool-ltdl glibc perl ntp

Step 3: Download the latest version of the Zimbra Mail Server

Visit Zimbra’s official site and download the latest version of Zimbra Collaboration Open Source Edition. Using the wget command, we’ll look for the latest version of Zimbra which is 8.8.15 for our case.

$ wget https://files.zimbra.com/downloads/8.8.15_GA/zcs-8.8.15_GA_3869.RHEL7_64.20190918004220.tgz

Step 4: Install Zimbra Mail Server

You will now extract the downloaded file using the tar command.

$ tar xvf zcs-8.8.15_GA_3869.RHEL7_64.20190918004220.tgz

In the extracted folder, run the install script.

cd  zcs-8.8.15_GA_3869.RHEL7_64.20190918004220
./install.sh

At the bottom of the script, press Y to accept the license.

This will imply that we have successfully installed and configured the Zimbra mail server successfully on centOS 7. One more step and we will be fully done, we have to install and enable firewalld on our server.

Install and enable firewalld

With the following commands, you will be able to install firewallD on the centos server although some centos versions have it installed by default.

sudo yum install firewalld
sudo systemctl start firewalld
sudo systemctl enable firewalld

Now go ahead and allow the Zimbra admin panel’s service firewall.

$ firewall-cmd --permanent --add-port=7071/tcp
success
$ firewall-cmd --reload
success

To access Zimbra as an admin, go to your browser and type in your URL as shown below.

https://techies.com:7071/zimbraAdmin/

after logging in, the page will appear like this;

To access Zimbra as a user, use the following URL;

https://techies.com

After logging in, the page will look like the one below;

Both credentials can be able to be used for both admin and user login.

You are now good to use the Zimbra mail server for your work or personal business.

Conclusion
We have successfully installed the Zimbra mail server on centOS and configured it. We hope you’ll find this tutorial interesting. Thank you for visiting our site.
