How to Install Zimbra 9 Open Source Edition by ZeXtras on CentOS 8

Posted by

In the previous article, I am using Zimbra Open Source Edition created by Beezim. In this article, I am using Zimbra 9 Open Source Edition unofficial created by ZeXtras. You can find full information about Zimbra 9 OSE created by ZeXtras here: https://www.zextras.com/zimbra-9/.

If you are looking for a Zimbra 9 installation on CentOS 7, please see this one: How to Install Zimbra 9 Open Source Edition (Unofficial) on CentOS 7. If you are looking for a Zimbra 9 installation on Ubuntu, please see this one: How to Install Zimbra 9 Open Source Edition (Unofficial) on Ubuntu.

Here is how I install Zimbra 9 FOSS (unofficial) on CentOS 8 created by ZeXtras

# Install EPEL Repo

yum install epel-release -y
yum update -y
yum upgrade -y

# Install screen and wget

yum install wget screen -y

# Download script automatic configuration

This script will automatically configure /etc/hosts, hostname, create local DNS using BIND and install dependencies that required by Zimbra

screen -S install-zimbra
wget -c https://raw.githubusercontent.com/imanudin11/zimbra-auto-install/master/setup-zimbra-cento8.sh
chmod +x setup-zimbra-cento8.sh
./setup-zimbra-cento8.sh

Screen commands are used for background processes. When the SSH connection is lost, I can reconnect to the server and check the progress by running the screen -x.

When the script is run, you will be asked about the hostname, domain, and IP address. Below is the information I used

[INFO] : Configuring /etc/hosts

Hostname. Example mail : mail
Domain name. Example imanudin.net : imanudin.net
IP Address : 192.168.11.12

Why not using a modern web app after login? as mention on Zimbra Wiki “A Zimbra Network Edition license is required to use the Modern Web App.”. So, you should buy Zimbra NE to get more Benefits 🙂

Congratulations, you had been finished install Zimbra 9 on CentOS 8. After install, you can improve anti-spam with some method below. This method is still relevant for Zimbra 9 🙂

Good luck 🙂

    In version 9 do we have active – active mailbox sync feature available? Zimbra used to promise that in version they will provide mailbox sync feature. I am checking the release notes but didn’t see anything related to that.

    Thank you.

  2. Hello Ahmad,
    Just an off topic question. I made some modifications in the distribution list. But, when I try to send email to the distribution list I just modified, its showing the old name and contacts. Can you kindly guide me what I should to refresh the changes?
    Thank you!

    1. Hi,
      Please try to decrease the interval polling GAL from Zimbra admin | configure | domains | Edit your domains. Or you can enforce GAL Sync by this command

      zmgsautil forceSync -a galsync@domain.com -n InternalGAL
      

      You can find gal account name with this command

      zmprov -l gaa | grep -i galsync
      
      1. ada tutorial cara upgradenya kang? ato bisa saya migrasi langsung dari zimbra 8.8.11 ke zimbra 9 ini kang? apa yg harus saya lakukan kang?

        1. Untuk upgrade bisa langsung dilakukan. Pastikan dibackup full dulu dan backupnya aman.

          Proses upgrade, sama seperti instalasi biasa

          1. Download binary yang sesuai OS
          2. Ekstrak
          3. Install dengan perintah ./install.sh
          4. Jika ditanya do you want to upgrade? pilih yes
          5. Tunggu hingga proses upgrade selesai

          Jika butuh prof services, saya bisa ko bantuin proses upgradenya 😀

  3. ada tutorial cara upgradenya kang? ato bisa saya migrasi langsung dari zimbra 8.8.11 ke zimbra 9 ini kang? apa yg harus saya lakukan kang?

  4. Hi iMan
    So good document and if I would like use Nextcoud to intergrate Zimbra 9 LDAP with SSL, could you please recommend ?

    Regards,
    Ya

    1. Hi Funig,
      No. I have not to try to install ZeXtras Suite over ZCS9 directly from the installer. But I am sure ZeXtras Suite is Supported because it already production on Zimbra NE (as Network NG Module) :). Except for the Zoom and Slack integration :). However, you can check the roadmap. ZeXtras has some plan to improve its product: https://www.zextras.com/roadmap-2020/

  5. Dear Ahmad Imanudin,
    Good morning, I have installed and configured Zimbra 8.7.11 version in my Centos Linux system. Now I am facing issues after enabled auto copies, I am receiving multiple duplicates copies. Please help me to stop the same.
    Regards,
    Balaji V
