Steps to install Gitlab on Rocky Linux

1. Perform System Update

It's recommended to update your system before installing any new software, especially if you plan to install GitLab. Run the following command to update your system:

$ sudo dnf check-update
$ sudo dnf update -y
$ sudo dnf -y upgrade

2. Configure SSH

You can skip this step if SSH is already enabled on your system.

Download and install the OpenSSH-server perl package with this command:

$ sudo dnf install -y curl policycoreutils openssh-server perl

To check the status of the OpenSSH daemon, run the following command:

$ sudo systemctl status sshd

Next, Enable the daemon with this command:

$ sudo systemctl enable sshd

Now start the ssh service by running this command:

$ sudo systemctl start sshd

3. Configure Firewall

Here, we will configure the system firewall to allow HTTP and HTTPS access. This is also an optional step; you can skip it.

To check the status of the firewall, run:

$ sudo systemctl status firewalld

To open HTTP service on the system firewall, use this command:

$ sudo firewall-cmd --permanent --add-service=http

Now add HTTPS service on the system firewall with this command:

$ sudo firewall-cmd --permanent --add-service=https

To update configurations, restart the firewall.

$ sudo systemctl reload firewalld

4. Install Postfix

To send notification emails, we will need to install Postfix. If you want to use another service to deal with notification emails, like SMTP, you can skip this step. You can configure the settings after installation.

To use the Postfix service, install it with the below command:

$ sudo dnf install postfix

Once the installation is completed, enable the service with the help of this command:

$ sudo systemctl enable postfix

Now start the service with this command:

$ sudo systemctl start postfix

A configuration screen will appear during the installation of Postfix. Select 'Internet Site' and press enter. For DNS configuration, use your server's external DNS for 'mail name'. In case more screens appear, keep pressing enter to accept the default configurations.

5. Add and Install GitLab package

Here we will download and install GitLab on our system.

To add the GitLab package repository, run this command:

$ curl | sudo bash

To install the package, we will run the command below. Make sure to change to the URL at which you want to run your GitLab instance:

$ sudo EXTERNAL_URL="" dnf install -y gitlab-ee

Once the installation is all done, try accessing the external URL that you gave for GitLab. This will open GitLab login page for you.

A random password will be generated and stored in the /etc/gitlab directory with the name initial_root_password.

To log in, use root as your username and the password stored in the initial_root_password file. The password file will automatically be deleted after 24 hours. Make sure to reset the password.
