How to Install Zimbra 10 Open Source Edition on Rocky Linux

Posted by

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

System information

IP Address :
Domain :
Hostname : mail

# Configure hosts and hostname

vi /etc/hosts

Fill in the /etc/hosts file as follows   localhost	mail

Run the following command to setup hostname

hostnamectl set-hostname

# 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


Restart dnsmasq service

systemctl enable --now dnsmasq
systemctl restart dnsmasq

# /etc/resolv.conf Configuration

Adjust /etc/resolv.conf as follows


Test DNS using host command

host -t MX
host -t A

The result will look like below

root@mail:~# host -t MX mail is handled by 10
root@mail:~# host -t A has address

# Download Zimbra 10 OSE

Download Zimbra 10 OSE for Rocky Linux from this link: 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.


Extract and Install Zimbra

cd /opt/
tar -xvf zcs-10.0.0_GA_0001.RHEL8_64.20230824154520.tgz
cd zcs-10.0.0_GA_0001.RHEL8_64.20230824154520

    1. Hello,
      The process are :
      – Download new Zimbra installer from Ian (if he create a new one)
      – Extract and install as usual
      – When installation, you will be asked about upgrade

    1. Hi,
      You can download the new zimbra version. Then run as usual. When you are asked to upgrade, type yes. The upgrade process is no different from a fresh installation. However, make sure you make a backup first

      1. Hi Imanudin Ahmad:
        I would like to take this opporunity say thank you for your excellent installation information on Rocky Linux!!
        Did you use Rocky Linux version 9.3 or 9.2?

        I was already setup on Ubuntu 20.04, using Zimbra zcs-8.8.15_GA_4179.UBUNTU20_64. When I updated to zcs-10.0.5_GA_0423.UBUNTU20_64, I used the following command with no issues:

        root@mail:~# ./ –skip-ng-check –skip-activation-check

        I hope this will others who wish to update to Zimbra 10 Open Source Edition!

        Again, thank you!!

        1. Hi,
          No, I did not use Rocky Linux 9.x. Currently Rocky Linux 9 is not supported by Zimbra.

          Thanks for your zimbra upgrade experience. Your experience will help a lot who want to upgrade their Zimbra

  1. Hi,

    I installed it successfully, and I can login admin account from normal login page.
    But when I open admin console to login the same admin account, but I got “Authentication Fail” message.

    I don’t know why I can use the same account and password to login normal login page, but can’t use the same account to login admin console.
