How to install and Set up Gitlab CE Server on Ubuntu 22.04

GitLab allows you to host an on-premise Git repository that can be accessed from either your local LAN or (if you have an available public IP address) from outside your company. GitLab is an open-source repository manager based on Rails developed by GitLab Inc. It is a web-based git repository manager that allows your team to collaborate on coding, testing, and deploying applications. GitLab provides several features, including wikis, issue tracking, code reviews, and activity feeds.

In this guide, we will install the GitLab CE on the Ubuntu 22.04. We will install the GitLab CE using the ‚Äėomnibus‚Äô package provided by GitLab.

# Prerequisites

  • Updated Ubuntu 22.04 server
  • Access to the internet
  • Ensure that your server is at lease 4GB of RAM with more than 20GB of disk space and 2 CPUs

# Table of Content

  • Ensure that the server packages are up to date
  • Installing GitLab CE

# Ensure that the server packages are up to date

Before proceeding let us update our Centos 8 server using this command:

sudo apt update
sudo apt upgrade -y

Install common packages that will be essential

sudo apt install -y vim

# Install and configure the necessary dependencies

Before proceeding let’s ensure that the pakages needed are installed. Use this command:

sudo apt install -y curl openssh-server ca-certificates tzdata perl

Next, install Postfix to send notification emails. If you want to use another solution to send emails please skip this step and configure an external SMTP server after GitLab has been installed.

sudo apt install -y postfix

During Postfix installation a configuration screen may appear. Select ‚ÄėInternet Site‚Äô and press enter. Use your server‚Äôs external DNS for ‚Äėmail name‚Äô and press enter. If additional screens appear, continue to press enter to accept the defaults.

# Add the GitLab package repository and install the package

Add the GitLab package repository.

curl | sudo bash

Next, install the GitLab package. Make sure you have correctly set up your DNS, and change to the URL at which you want to access your GitLab instance. Installation will automatically configure and start GitLab at that URL.

For https:// URLs, GitLab will automatically request a certificate with Let’s Encrypt, which requires inbound HTTP access and a valid hostname. You can also use your own certificate or just use http:// (without s).

If you would like to specify a custom password for the initial administrator user (root), check the documentation. If a password is not specified, a random password will be automatically generated.

sudo apt update
sudo EXTERNAL_URL="" apt install gitlab-ce

# Configuring Gitlab CE

Now that gitlab is successfully installed, let‚Äôs configure it. The main configuration file can be found in the file/etc/gitlab/gitlab.rb. Open the file (vim /etc/gitlab/gitlab.rb) and confirm that the external url is set as defined during installation:

external_url ''

Save & and run the reconfiguration script

sudo gitlab-ctl reconfigure

Wait for the configuration script to finish. You should see something similar to this:

Recipe: monitoring::alertmanager
  * runit_service[alertmanager] action restart (up to date)
Recipe: monitoring::postgres-exporter
  * runit_service[postgres-exporter] action restart (up to date)
Recipe: monitoring::grafana
  * runit_service[grafana] action restart (up to date)

Running handlers:

gitlab Reconfigured!

# Accessing Gitlab CE

Once the configuration is complete, Gitlab CE is available in the URL provided (In my case Ensure that the DNS entry for the URL is pointing to the server then access that url in the browser. You should be redirected to the login page as shown below:

Gitlab CE Sign in Page

Unless you provided a custom password during installation, a password will be randomly generated and stored for 24 hours in /etc/gitlab/initial_root_password. Use this password with username root to login.

sudo cat /etc/gitlab/initial_root_password

Once logged in you can use the gitlab server to create and manange projects and repositories.

# Conclusion

Congratulations, you now have your local GitLab up and running.  You can now use your Gitlab CE Server to manage repositories and projects.
