Detailed introduction to the installation and configuration process of GitLab

In today's software development field, version control is a very important job, and Git is one of the most popular version control systems in this field. However, in order to better manage your own projects, you also need to build a Git server for code submission and management. Among them, GitLab is an excellent choice. This article will introduce the installation and configuration process of GitLab in detail.

Step 1: Install the required software packages

Before starting to install GitLab, we need to install the software packages that GitLab depends on, including curl, policycoreutils-python, postfix (or others mail service package), openSSL-devel and the decompression tool unzip. You can install it using the following command:

sudo yum install curl policycoreutils-python postfix 
sudo dnf install curl policycoreutils-python-utils 
sudo apt-get install curl postfix

Then install the OpenSSL library:

sudo yum install -y openssl-devel

Step 2: Install GitLab-ce

We can find it from the official GitLab download page Required installation packages and download them. However, for convenience, we can use the officially maintained installation script for installation. Use the following command to download and install:

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

Step 3: Configure GitLab

After the installation is complete, we need to perform some necessary configuration work so that GitLab can work normally.

First, start the GitLab server:

sudo gitlab-ctl reconfigure

This command will automatically perform a series of configuration work, including creating necessary users, groups, databases, etc. This process may take a long time and requires patience.

Secondly, configure GitLab’s external access address. By default, GitLab will listen to the 127.0.0.1 address, which can only be accessed locally. We can modify the configuration file to allow GitLab to listen to external addresses. Edit the /etc/gitlab/gitlab.rb file and change the value of external_url to your actual access address:

sudo vi /etc/gitlab/gitlab.rb
external_url 'http://gitlab.example.com'

Finally, re-run the configuration command:

sudo gitlab-ctl reconfigure

Step 4: Get started GitLab

Now, we can open the browser, enter the external access address configured above, and see the GitLab login page. You need to set the administrator account and password when entering for the first time, and then you can start using it.

Summary:

This article introduces the installation and configuration process of GitLab in detail, allowing you to quickly build your own Git server. However, special attention needs to be paid to security issues to avoid security vulnerabilities. Pay attention to backup and maintenance during daily use to avoid data loss.
