How to Install Zimbra 10 Open Source Edition on Rocky Linux

In this article, I used Zimbra 10 OSE created by ianw1974.

System information

IP Address : 192.168.56.11
Domain : imanudin.web.id
Hostname : mail

# Configure hosts and hostname

vi /etc/hosts

Fill in the /etc/hosts file as follows

127.0.0.1   localhost
192.168.56.11 mail.imanudin.web.id	mail

Run the following command to setup hostname

hostnamectl set-hostname mail.imanudin.web.id

# Disable Selinux & Firewall

sed -i s/'SELINUX='/'#SELINUX='/g /etc/selinux/config
echo 'SELINUX=disabled' >> /etc/selinux/config
setenforce 0
service firewalld stop
service iptables stop
service ip6tables stop
systemctl disable firewalld
systemctl disable iptables
systemctl disable ip6tables

# Disable service sendmail or postfix (if any)

systemctl disable --now sendmail
systemctl disable --now postfix

# Update repo and install dependencies

Install EPEL Repo

yum update
yum install epel-release

Install dependencies

yum update -y
yum upgrade -y
yum -y install perl perl-core wget screen tar openssh-clients openssh-server dnsmasq bind-utils unzip nmap sed nc sysstat libaio rsync telnet aspell net-tools rsyslog

# Setup local DNS

vi /etc/dnsmasq.conf

Adjust /etc/dnsmasq.conf as follows

server=8.8.8.8
mx-host=imanudin.web.id,mail.imanudin.web.id,10
host-record=imanudin.web.id,192.168.56.11
host-record=mail.imanudin.web.id,192.168.56.11

Restart dnsmasq service

systemctl enable --now dnsmasq
systemctl restart dnsmasq

# /etc/resolv.conf Configuration

Adjust /etc/resolv.conf as follows

nameserver 127.0.0.1
nameserver 8.8.8.8
nameserver 1.1.1.1
search imanudin.web.id

Test DNS using host command

host -t MX imanudin.web.id
host -t A mail.imanudin.web.id

The result will look like below

root@mail:~# host -t MX imanudin.web.id
imanudin.web.id mail is handled by 10 mail.imanudin.web.id.
root@mail:~# host -t A mail.imanudin.web.id
mail.imanudin.web.id has address 192.168.56.11

# Download Zimbra 10 OSE

Download Zimbra 10 OSE for Rocky Linux from this link: https://techfiles.online/zimbra/. Then save it to the /opt/ folder

# Extract and install Zimbra 10 OSE

Run the screen command first before installing Zimbra. I always use “screen” for prevention If installing using remote installation such as SSH to the server.

screen
