by ·

GitLab Community Edition (CE) is a free and open-source platform for managing Git repositories. It offers a variety of features, including a wiki, issue tracking, and continuous integration/continuous deployment (CI/CD) capabilities. This guide will walk you through the process of downloading and installing GitLab CE on your server, step by step.

Key Takeaways

  • Ensure your server meets the system requirements before starting the installation.
  • Install necessary dependencies and packages to prepare your server for GitLab CE.
  • Download and run the GitLab CE installer to set up the platform.
  • Configure GitLab CE by editing the configuration file and setting up SSL.
  • Access and explore your GitLab instance, and secure it with HTTPS and firewall rules.

Preparing Your Server for GitLab CE

Before diving into the installation of GitLab CE, it’s crucial to prepare your server properly. This ensures a smooth installation process and optimal performance.

Installing Dependencies

Installing Required Packages

First, refresh your local package index with sudo apt update. Then, install the necessary dependencies by running:

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

You might already have some of these packages installed. For the postfix installation, select Internet Site when prompted. Enter your server’s domain name to configure mail sending.

Adding GitLab Repository

Next, move into the /tmp directory:

cd /tmp

Download the GitLab repository installation script:

curl -LO https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh

Run the script to add the GitLab repository:

sudo bash script.deb.sh

Running the Installation Script

With the repository added, you can now install GitLab. Run the following command to install GitLab CE:

sudo apt install gitlab-ce

This script will configure your system with the GitLab repositories and install the necessary packages. Now that you have the dependencies installed, you’re ready to move on to the next step.

Downloading and Installing GitLab CE

Now that your server is ready, it’s time to download and install GitLab CE. Follow these steps to get GitLab up and running on your system.

Configuring GitLab CE

Editing the Configuration File

First, you need to open the GitLab configuration file. Use a text editor like nano to make changes. This file is crucial for setting up your GitLab instance. You can find it at /etc/gitlab/gitlab.rb. Make sure to set your domain name correctly.

Setting Up SSL with Let’s Encrypt

To secure your GitLab instance, enable SSL using Let’s Encrypt. This will encrypt data between your server and users. Run the following command to set it up:

sudo gitlab-ctl reconfigure

Reconfiguring GitLab

After making changes to the configuration file, you need to reconfigure GitLab. This applies all the settings you’ve changed. Simply run:

sudo gitlab-ctl reconfigure

Reconfiguring ensures that all your settings are applied correctly. It’s a quick process but very important.

Once done, navigate to your domain in a web browser to start using GitLab CE.

Accessing Your GitLab Instance

Logging In for the First Time

Visit the domain name of your GitLab server in your web browser: https://your_domain. On your first visit, you’ll be greeted with a login page. GitLab generates an initial secure password for you. It is stored in a folder that you can access as an administrative sudo user. Use this password to log in and set up your account.

Setting Up Your Profile

One of the first things you should do after logging in is change your password. Click on the icon in the upper-right corner of the navigation bar and select Edit Profile. You’ll then enter a User Settings page. On the left navigation bar, select Password to change your GitLab generated password to a secure password, then click on the Save password button when you’re finished with your updates.

Exploring GitLab Features

Now that you’re logged in, you can begin to import or create new projects and configure the appropriate level of access for a team. GitLab is regularly adding features and making updates to their platform, so be sure to check out the project’s home page to stay up-to-date on any improvements or important notices.

Managing GitLab Services

Starting and Stopping GitLab

To keep your GitLab instance running smoothly, you need to know how to start and stop the services. Use the following commands:

  • Start GitLab: sudo gitlab-ctl start
  • Stop GitLab: sudo gitlab-ctl stop
  • Restart GitLab: sudo gitlab-ctl restart

These commands ensure that your GitLab services are running as expected. Always restart GitLab after making significant changes to the configuration.

Checking Service Status

It’s crucial to regularly check the status of your GitLab services. Use the command sudo gitlab-ctl status to get a detailed report. This command will show you which services are running and if there are any issues. Keeping an eye on the status helps in maintaining a healthy GitLab environment.

Troubleshooting Common Issues

Even with the best setup, you might encounter issues. Here are some common problems and their solutions:

  • Service not starting: Check the logs using sudo gitlab-ctl tail.
  • Slow performance: Ensure your server meets the system requirements and isn’t overloaded.
  • Login issues: Verify your domain settings and SSL certificates.

If you face persistent issues, refer to the official GitLab documentation for more detailed troubleshooting steps.

Managing your GitLab services effectively ensures a smooth and efficient workflow. Regular checks and timely troubleshooting can save you from bigger problems down the line.

Securing Your GitLab Instance

Ensuring your GitLab instance is secure is crucial for protecting your code and data. Follow these steps to enhance the security of your GitLab setup.
