Best Practices for GitLab in Debian

When installing and configuring GitLab in Debian systems, following best practices can help ensure system stability, security, and efficiency:

Preparations before installation

1. Update the system package :

 sudo apt-get update

2. Install the necessary dependencies :

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

3. Add the official GitLab repository :

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

Install GitLab

1. Install GitLab CE :

 sudo EXTERNAL_URL="http://your_server_ip" apt-get install gitlab-ce

Please replace http://your_server_ip with your server IP address or domain name.

Configure GitLab

1. Configure external URL :

Edit the /etc/gitlab/gitlab.rb file, locate external_url 'http://your_server_ip' and make sure it is set correctly. For example:

 external_url 'http://192.168.1.100'

2. Reconfigure and restart GitLab :

 sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

3. Set firewall rules :

 sudo ufw allows 80
sudo ufw allows 443
sudo ufw reload

Best Practices for GitLab in Debian

1. Determine the appropriate branching strategy :

   • Determine branch strategies based on team size, experience level, expansion requirements and industry restrictions.
   • Common workflows include centralized workflows, feature branches, GitFlow, and GitLab Flow.

2. Make frequent minor changes :

   • Simplify the project into small steps and submit frequently to achieve larger goals.
   • The culture of frequent submissions ensures that everyone knows what teammates are doing.

3. Write descriptive submission information :

   • Submit messages should reflect the intent, not just the content submitted.
   • Establish a submission message convention to ensure consistency between teams.

4. Use CI/CD to make database changes :

   • Include database changes into the application release process.
   • Use tools such as Bytebase to automate SQL auditing and release processes.

5. Configure Nginx reverse proxy (if using Nginx instead of the default GitLab HTTP server):

   • Create a new nginx configuration file gitlab.conf.
   • Introduce gitlab.conf in nginx main configuration file.
   • Modify the gitlab configuration file to disable the nginx server that comes with GitLab.

6. Monitoring and logging :

   • Regularly check GitLab's log files to monitor the health of the system.
   • Use GitLab's monitoring tools to track performance metrics.

7. Security :

   • Update GitLab regularly to the latest version for security patches.
   • Configure SSH key authentication to ensure the security of the repository.

8. Backup :

   • Regularly back up GitLab's data and configuration files to prevent data loss.

Following these best practices can help you run GitLab efficiently and securely on your Debian system, improving team collaboration efficiency and project delivery speed.
