How to install Zimbra Collaboration Open Source 8.8.12_GA on CentOS 7

Requirements:

• CentOS 7
• 10 GB RAM
• 5 GB Free Space on /opt/Zimbra
• 10 GB free disk space on /opt
• 10 GB free disk space on /tmp
• Fully Qualified Domain Name (FQDN), in this demo is “mail.ibtechpa.local”
• Record A & MX for your Server
• The firewall should be disabled

Become the root user:

# sudo su -

or
# su -

Apply the latest updates using following command and then reboot:

# yum update -y
# reboot

Install Zimbra dependencies:
# yum install unzip net-tools sysstat libaio nmap-ncat libstdc++.so.6 openssh-clients perl-core wget libreoffice libreoffice-headless -y

Set the hostname of your server:

# hostnamectl set-hostname mail.ibtechpa.com
# exec bash

Edit hosts file:

# vi /etc/hosts

Add:

192.168.1.141 mail.ibtechpa.com mail

# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.141 mail.ibtechpa.com mail

Zimbra recommends the firewall to be disabled:
# systemctl stop firewalld
# systemctl disable firewalld

In CentOS 7, postfix is installed and running by default. So, we need to disable it for Zimbra installation:
# systemctl stop postfix
# systemctl disable postfix

Create Zimbra directory to place the installer:

# mkdir /zimbra
# cd /zimbra

Download the Zimbra 8.8.12_GA:
# wget https://files.zimbra.com/downloads/8.8.12_GA/zcs-8.8.12_GA_3794.RHEL7_64.20190329045002.tgz

Extract the downloaded file:

# tar -zxvf zcs-8.8.12_GA_3794.RHEL7_64.20190329045002.tgz

Go to extracted folder and run the install script:
# cd zcs-8.8.12_GA_3794.RHEL7_64.20190329045002
[root@mail zcs-8.8.12_GA_3794.RHEL7_64.20190329045002]#

# ./install.sh

You will get text-based installation wizard. Press Y to accept the Zimbra license agreement:
