Let’s talk about the installation steps of GitLab

GitLab is an online code hosting, version control, project management and collaboration tool based on Git. It not only provides complete Git warehouse management functions, but also a complete CI/CD integration platform, providing a series of applications such as code review, code management, testing, code construction, and deployment, etc., allowing the development team to improve the efficiency of code development, testing, and deployment. and code maintenance are more efficient and collaborative. This article will introduce the installation steps of GitLab.

1. Install the necessary software packages

Before installation, you need to install the necessary software packages to run GitLab, including curl, openssh-server, ca-certificates, and mail server (SMTP ). Use the following command to install the above software package:

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

During the installation, you will be prompted to select an email configuration type. By default, "Internet Site" is generally selected.

2. Add GitLab software source

The next step is to add GitLab official software source. Copy the following command to the terminal and execute it:

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

If your system is Debian 7 (Wheezy), use the following command:

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo os=debian dist=wheezy bash

3. Install GitLab

After adding After the software source is available, you can use the following command to install GitLab:

sudo apt-get install gitlab-ce

This process may take some time because it requires downloading the GitLab installation package and installing it.

4. Configure GitLab

After the installation is completed, open the GitLab configuration file /etc/gitlab/gitlab.rb separately and modify it as needed. Commonly used configurations include:

• Configuring the mail server: You can use an external mail server or locally configured SMTP. When modifying

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.server.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "smtp-user"
gitlab_rails['smtp_password'] = "smtp-password"
gitlab_rails['smtp_domain'] = "smtp.server.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = false
gitlab_rails['smtp_tls'] = true
gitlab_rails['smtp_openssl_verify_mode'] = 'peer'

in the gitlab.rb file, you need to fill in the address, port, authentication information, etc. of the SMTP server according to the actual situation.

• Modify the GitLab listening port: Find the external_url in the /etc/gitlab/gitlab.rb file. When port 80 is not used, you need to modify it to the following format:

external_url 'http://gitlab.example.com:8080'

The default ports are 80 and 443.

• Writing of hooks: Hook scripts can be defined in /opt/gitlab/embedded/service/gitlab-shell/hooks.

5. Restart GitLab

After modifying the configuration file, you need to restart GitLab to make it take effect. Use the following command to restart GitLab:

sudo gitlab-ctl reconfigure

You can also use the following command to restart all GitLab components:

sudo gitlab-ctl restart

In this way, a GitLab is installed and you can enter http://your_server_ip in the web browser Access the GitLab server.

Summary

The above is the GitLab installation process under the Ubuntu system. Under other operating systems, the installation process may be slightly different, but the basic steps are similar. I hope this article can help you install GitLab in your environment.
