How to set up gitlab server on Ubuntu

As the software development process continues to improve, version control tools have become a key component. Git is one of the most commonly used version control tools today. The biggest advantage of Git is distributed version control, which allows developers to collaborate on development at different locations and times. GitLab is a web application controlled and managed by Git. It provides open source Git code hosting, issue tracking, CI/CD and wiki functions. In this article, we will introduce how to set up GitLab server on Ubuntu operating system.

Step 1: Install the necessary software packages

Before you start, you need to install some necessary software packages on the machine. These packages can be installed with the following commands.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install curl openssh-server ca-certificates postfix

When you are prompted to configure your mail server, select "Internet Site" and answer the radio option "General type of mail configuration".

Step 2: Install GitLab

Before installing GitLab, you need to configure the source of GitLab. Create a new file /etc/apt/sources.list.d/gitlab-ce.list and write the following content.

deb https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/ubuntu xenial main

Then execute the following command.

curl https://packages.gitlab.com/gpg.key 2> /dev/null | sudo apt-key add -
sudo apt-get update
sudo apt-get install gitlab-ce

Note: The mirror source of Tsinghua University is used here because it is faster than the official source.

Step 3: Configure GitLab

After the installation is complete, some configuration is required. Open the GitLab configuration file /etc/gitlab/gitlab.rb.

sudo nano /etc/gitlab/gitlab.rb

Found the following.

# gitlab_external_url 'http://gitlab.example.com'

Uncomment and replace http://gitlab.example.com with your domain name or the IP address of the server.

gitlab_external_url 'http://your_domain_or_IP'

Next, find the following content.

# unicorn['port'] = 8080

Uncomment and change the port number to 80.

unicorn['port'] = 80

Finally, execute the following command and wait for GitLab to start.

sudo gitlab-ctl reconfigure

Step 4: Access GitLab

After completing the above steps, you can enter http://your_domain_or_IP in the browser to access GitLab. When you access GitLab for the first time, you will be asked to set up an administrator account. After the setup is complete, you can start using GitLab.

Summary

In this article, we introduced how to set up a GitLab server on the Ubuntu operating system. In the process of building the server, we need to install the necessary software packages, configure the source of GitLab, install GitLab and perform related configurations, and access GitLab. Hope this article can be helpful to you.
