How to set up gitlab? Minimum required sharing

GitLab is a web-based Git repository management tool that allows teams to collaborate on a project and share code. It provides various features such as source code management, issue management, continuous integration, wiki and code review, etc. A very practical and essential tool for any organization with software development needs. If you plan to use GitLab, the following are several requirements that need to be met:

1. Hardware requirements
Since GitLab is a resource-intensive application, there must be sufficient hardware resources to support it. The following are the minimum hardware requirements recommended by GitLab:

• 4 core CPU
• 8GB RAM
• 25GB disk space (Git repository size is not included)

When configuring the server, you need to consider the expected number of concurrent users, Git warehouse size, and resource requirements to provide sufficient hardware resources for GitLab.

2. Operating system requirements
GitLab supports a variety of operating systems, such as Ubuntu, Debian and CentOS. However, for best performance and compatibility, it is recommended to use Ubuntu or Debian as GitLab's operating system.

3. Installation and configuration requirements
Installing and configuring GitLab is a relatively complex process that requires consideration from many aspects. For example, if you want to configure GitLab for HTTPS access, you will need to generate and install an SSL certificate for GitLab. In addition, you also need to configure the mail server for GitLab to receive notifications, create users, etc.

In addition, GitLab also requires necessary software and tools to be installed on the server, such as Ruby, PostgreSQL, NGINX, and Git itself. Installing these software requires certain technical knowledge and experience and should be done by experienced IT professionals.

4. Backup and recovery requirements
For any application in a production environment, backup and recovery are crucial. GitLab is no exception. If you use GitLab in a production environment, you need to regularly back up your Git repository and database. Additionally, you need to know how to recover GitLab if the server crashes.

5. Security Requirements
The security of GitLab is an important issue. You need to pay attention to the following points:

• Install a firewall on the server to restrict remote access to GitLab
• Disable unnecessary services and ports and allow only necessary services and ports
• Perform regular updates to the server and ensure that all security patches have been installed
• Configure for GitLab Appropriate security policies, such as password complexity, use of HTTPS, etc.
• Enforce strict permission control on all code review requests to ensure that only appropriate personnel can review and merge code.

6. Maintenance requirements
In order to ensure the stability and performance of GitLab, you need to perform regular system maintenance and tuning on GitLab. For example, you need to ensure that both GitLab and your database are up to date, and you need to regularly clean up useless data and files. In addition, you also need to monitor GitLab's system resource usage, such as memory, CPU, and disk space, and regularly back up your Git repository and database.

However, if you don’t want to tediously set up a GitLab environment, you can also consider using the cloud hosting service provided by GitLab, which can automatically configure all the requirements of GitLab, making it easy to use GitLab.
