How to set up your own GitLab server

With the rise of open source and cloud computing, GitLab has gradually become one of the most popular code warehouse services. It provides powerful and practical functions, including code repository, code review, CI/CD, etc. Building your own GitLab server has become a choice for more and more people. This article will introduce how to set up your own GitLab server.

1. Purchase VPS host

First, you need to purchase a VPS host. VPS hosting is a type of virtual server usually available on cloud computing platforms. They provide better security and customizability, making them the first choice for building GitLab servers.

2. Install GitLab

Next, you need to install GitLab. The following are the installation steps:

2.1 Install the necessary software

Before starting to install GitLab, we need to install the necessary software. These software include curl, openssh-server, ca-certificates and postfix. You can install them using the following command:

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

2.2 Add GitLab repository

You need to add GitLab repository added to the system.

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

2.3 Install GitLab

Now you can install GitLab. Install GitLab using the following command:

sudo apt-get install gitlab-ce

3. Configure GitLab

After installing GitLab, we need to configure some details .

3.1 Configure domain name and SSL authentication

First, you need to configure GitLab’s domain name and SSL authentication. This will ensure that your GitLab server has a secure identity and that you can access it over HTTPS. You can configure an SSL certificate for your GitLab server using the following command:

sudo openssl req -newkey rsa:2048 -nodes -keyout /etc/gitlab/ssl/gitlab.example.com.key -out /etc /gitlab/ssl/gitlab.example.com.csr

sudo openssl x509 -req -days 365 -in /etc/gitlab/ssl/gitlab.example.com.csr -signkey /etc/gitlab/ssl /gitlab.example.com.key -out /etc/gitlab/ssl/gitlab.example.com.crt

Replace "example.com" with your domain name.

3.2 Configuring GitLab Access

GitLab allows you to create different users and user groups. By default, your GitLab server is not accessible to anyone except administrators. You can add a new user to your GitLab server using the following command:

sudo gitlab-rails console

Here you can execute the following command on the console to create a new user:

user = User.new(:name => 'New User', :username => 'new_username', :email => 'new_user@example.com', :password => 'password' , :password_confirmation => 'password')

user.save

3.3 Configure SMTP server

You need to configure an SMTP server so that GitLab can send emails. You can add an SMTP server to GitLab using the following command:

sudo vim /etc/gitlab/gitlab.rb

Add the following statement under "gitlab_rails['smtp_enable']":

gitlab_rails['smtp_address'] = "smtp.gmail.com"

gitlab_rails['smtp_port'] = 587

gitlab_rails['smtp_authentication'] = "plain"

gitlab_rails['smtp_enable_starttls_auto'] = true

gitlab_rails['smtp_user_name'] = "youremail@gmail.com"

gitlab_rails['smtp_password'] = "password"

Update settings:

sudo gitlab-ctl reconfigure

4. Using GitLab

Now that you have configured GitLab, you can start using it. Create your first project easily. Just log in to your GitLab server, create a new project and add code to it. With GitLab, you can easily conduct code reviews and build automated pipelines. You can also set access rights and control user permissions for each project.

Summary:

Setting up your own GitLab server may require some technical knowledge, but it can provide you with many benefits. Not only does it make code development and collaboration more efficient, it also helps you strengthen security. Although it takes some time and a lot of learning, it can lead to your team being more collaborative and having better coding practices.
