   GitLab has two installation packages: CE (Community Edition) and EE (Enterprise Edition). You can choose different versions according to your needs. The CE version is free, while the EE version requires payment but offers more features and support.

Visit https://about.gitlab.com/install/ and select the appropriate version to download. I choose the CE version for demonstration here. Before downloading, you need to select the desired installation method, including Docker, compiling from source code and downloading the installation package.

   GitLab is an application software containing multiple components, and it needs to rely on other software to run properly.

Before starting the installation, you need to install the following dependent software:

• curl
• openssh-server
• ca-certificates
• postfix
• tzdata

Install the dependent software through the following command:

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

During the installation process, you need to select a configuration template for Postfix . I selected "Internet Site" and set an email address for it. You can configure it according to your needs.

   The process of installing GitLab is very simple. First, upload the downloaded GitLab installation package to the server. If you downloaded the installation package through the wget command, you can skip this step.

After the upload is completed, please use the following command to decompress the installation package:

sudo tar -xf gitlab-ce-<version>.tar.gz

Next, enter the GitLab directory and run the installation command:

sudo dpkg -i gitlab-ce-<version>.deb

The installation process may It will take some time. After the installation is complete, you can reset GitLab's root password with the following command:

sudo gitlab-ctl reset-root-password

Now, you can access GitLab through your browser by accessing http://your-server-ip/.
