Install Zimbra Open Source Edition on your AlmaLinux server

To install Zimbra Open Source Edition on your AlmaLinux server, follow these steps using the command line:

1. Prepare your AlmaLinux Server

Ensure that your system is updated and the necessary dependencies are installed.

bash
sudo dnf update -y sudo dnf install -y wget net-tools perl unzip tar sysstat libaio nmap-ncat libstdc++ openssh-server epel-release

2. Set Hostname and DNS

Make sure your server's hostname is correctly set and that you have a valid DNS A and MX record pointing to the server.

Set your server hostname:

bash
sudo hostnamectl set-hostname mail.yourdomain.com

Check DNS records:

bash
dig yourdomain.com MX dig mail.yourdomain.com A

3. Disable Unnecessary Services

Stop and disable services that might conflict with Zimbra (Postfix, firewalld, etc.).

bash
sudo systemctl stop firewalld sudo systemctl disable firewalld sudo systemctl stop postfix sudo systemctl disable postfix

4. Download Zimbra Open Source

Go to the Zimbra website and download the latest version of Zimbra Open Source. Alternatively, use the command line to download it.

bash
wget https://files.zimbra.com/downloads/8.8.15_GA/zimbra-8.8.15_GA_3953.RHEL7_64.20200629025811.tgz

5. Extract Zimbra Package

Extract the downloaded package.

bash
tar xvfz zimbra-8.8.15_GA_3953.RHEL7_64.20200629025811.tgz cd zimbra

6. Run the Zimbra Installer

Run the Zimbra installation script.

bash
sudo ./install.sh

The installer will guide you through a series of options. Follow these steps:

  1. License Agreement: Accept the license agreement by typing Y.
  2. Package Selection: Select the default options for package installation, type Y to install the selected packages.
  3. DNS Configuration Warning: If you don’t have a split-DNS configuration, you’ll get a warning, but you can proceed if your public DNS is set correctly.
  4. Configuration Settings:
    • Choose the packages you wish to install. For a standard installation, all essential services like zimbra-core, zimbra-ldap, zimbra-store, zimbra-mta, and zimbra-dnscache will be selected.
    • Enter your domain name when prompted.
    • Set the admin password when prompted.

Once you've confirmed the configurations, the installer will complete the setup.

7. Access the Zimbra Admin Console

After installation, start Zimbra services:

bash
sudo su - zimbra zmcontrol start

You can now access the Zimbra Admin Console by navigating to:

arduino
https://mail.yourdomain.com:7071

Log in with the admin account you set up during the installation.

8. Configure Firewall (Optional)

If you're using a firewall, make sure to allow the necessary ports (e.g., 7071 for admin console, 443 for HTTPS, 25 for SMTP, etc.):

bash
sudo firewall-cmd --permanent --add-service={http,https,smtp,imap,pop3} sudo firewall-cmd --reload

Conclusion

You have now installed Zimbra Open Source Edition on your AlmaLinux server! Make sure to verify the installation by sending and receiving emails.
