How To Create Zimbra Account

Zimbra Collaboration Suite (ZCS) is an Open Source, collaborative platform for email servers, developed in two editions, Open Source edition (Free) and Network Edition (Paid), which provides services such as LDAP, SMTP, POP and IMAP, webmail client, calendaring, tasks, antivirus, antispam and others.

This tutorial describes how to install Zimbra Collaboration Suite Open Source Edition on a CentOS/RHEL 7 server.

Requirements

An external DNS server with both A and MX valid records to point to your Zimbra mail server IP Address.
A clean minimal installation of CentOS 8/RHEL 8 or CentOS 7/RHEL 7 without any mail, databases, LDAP, DNS, or Http servers up and running.
A static IP Address assigned to a network interface.

Step 1: Install System Packages

1. Before we proceed with Zimbra Collaboration Suite installation process, first log in to your server console with root privileges and install the following packages:

# yum -y install unzip net-tools sysstat openssh-clients perl-core libaio nmap-ncat libstdc++.so.6

Fig 01: Install Zimbra Required Packages

2. Next, issue getenforce command to check if Selinux is enabled on your machine. In case the policy is set to Enforced disable it by issuing the below commands:

# getenforce # setenforce 0 # getenforce

To completely disable Selinux on CentOS, open /etc/selinux/config file with a text editor and set the line SELINUX to disabled.

3. Assure that wget system utility is also installed on your system by issuing the following command:

# yum install wget

Step 2: Configure System Hostname

4. In order for Zimbra to function correctly you must set the local machine hostname and FQDN to point to your server IP Address by running the below hostnamectl commands from root account:

# hostnamectl set-hostname mail # echo "192.168.0.14  mail.centos7.lan  mail " >> /etc/hosts # cat /etc/hosts

Replace the system hostname and FQDN values accordingly in order to match your own domain settings. Test the hostname and FQDN values by issuing the ping command against both records.

# ping -c1 mail.centos7.lan # ping -c1 mail

Set Hostname in CentOS 7 — Fig 03: Set System Hostname

Step 3: Add a Static IP Address

5. If your server uses a DHCP dynamic IP Address, then you need to edit your network interface card and configure to use a static IP Address. Get the network interface information using ip addr command and identify your server external NIC (usually something like enp0s3 or eth0).

# ip addr

Then, run the nmtui-edit command against the interface you need to change settings and assign the interface with a manual IP Address. Use the below screenshots as a guide.

# nmtui-edit enp0s3

Configure Static IP Address to Network Interface — Fig 04: Get Network Interface Details and Configure Static IP

Fig 05: Configure Network Interface and DNS

Step 4: Disable Unwanted Services

6. A CentOS default installation ships with postfix daemon already installed and running. To disable and erase postfix service run the following commands:

# systemctl stop postfix # systemctl disable postfix # yum remove postfix

After the service has been removed issue the ss command in order to check if other daemons incompatible with Zimbra service, such as LDAP, httpd, dovecot are running on your system. If that's the case remove them as well.

Step 5: Install Zimbra Collaboration Suite Open Source Edition

7. Now it's time to install Zimbra Collaboration Suite. Go to Zimbra Collaboration Suite download page and grab the latest version on your system by issuing the following wget command:

-----------------          For RHEL/CentOS 8          ----------------- # wget https://files.zimbra.com/downloads/8.8.15_GA/zcs-8.8.15_GA_3953.RHEL8_64.20200629025823.tgz  -----------------          For RHEL/CentOS 7          ----------------- # wget https://files.zimbra.com/downloads/8.8.15_GA/zcs-8.8.15_GA_3869.RHEL7_64.20190918004220.tgz  -----------------          For RHEL/CentOS 6          ----------------- # wget https://files.zimbra.com/downloads/8.8.15_GA/zcs-8.8.15_GA_3869.RHEL6_64.20190918004220.tgz

Fig 07: Download Zimbra Collaboration Suite

8. After the download completes, use unzip command to extract the archive, enter Zimbra extracted directory and list the directory content to locate the installer file.

# tar xfz zcs-8.8.15_GA_3953.RHEL8_64.20200629025823.tgz # cd zcs-8.8.15_GA_3953.RHEL8_64.20200629025823/ # ls

9. Now, start Zimbra installation process by launching in execution the installer script file named install.sh.

After a series of system checks, the installer will prompt you to accept the license. Agree to the license (y) in order to continue further with the installation process.

# ./install.sh OR # ./install.sh --platform-override   [On different platforms other than RHEL]

Step 6: Zimba Initial Configuration

14. After the installation finishes, open a web browser and navigate to your domain name or IP address of the machine running Zimbra service, on port 7071 via HTTPS protocol, accept the certificate security error, and login with the credentials configured during the installation process. The default username for the Zimbra Admin web panel is admin.

https://mail.centos7.lan:7071 or https://192.168.1.14:7071

15. Once logged in the admin web console you can start adding your own SSL certificates, create mail accounts, mail aliases, and so on. Just remember that the port 7071 is used only for administrative tasks.

Clients can securely log in to their webmail boxes using the domain name or the server IP address via HTTPS protocol.

https://mail.centos7.lan  or https://192.168.1.14

Congratulations! Now you have a full operating mail stack installed on your premises.

Step 6: Remove or Uninstall Zimbra

If you wish to uninstall Zimbra service alongside with its components run the installer script with the -u option.

# ./install.sh -u
