Let’s talk about how to build nodes in gitlab

In recent years, with the continuous development of technology, Git has become one of the indispensable tools in everyone's daily development work. As a management platform for Git, GitLab can help us implement code version control, collaborative development, and code review. And if we want to use GitLab better, we need to build our own GitLab node. Today, this article will introduce to you how to set up a GitLab node.

1. Install GitLab

Before we begin, we need to install GitLab first. There are many ways to install GitLab, such as through binary packages, source packages, Docker, etc. Here we will introduce the installation through source code package.

1. Install necessary dependencies

Before installing GitLab, we need to install the necessary dependencies first. Open the terminal and enter the following command:

sudo apt-get update
sudo apt-get install -y curl openssh-server ca-certificates

2. Install the necessary software

After installing the necessary dependencies, we need to further install the necessary software. Enter the following command:

sudo apt-get install -y postfix

During the installation process, you will be prompted to choose the email configuration method, you can choose an Internet site or a satellite system. Select Internet site mode and follow the prompts to configure.

3. Install GitLab

Next, we enter the formal GitLab installation steps. Enter the following command:

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

The installation process may be time-consuming, so you need to wait patiently. After the installation is complete, we can try to access GitLab's virtual machine IP address (if you installed GitLab on a cloud server, it is the cloud server IP address). If it can be accessed normally, GitLab is installed successfully.

2. Configure GitLab

After installing GitLab, we need to perform some configuration operations on GitLab. Specifically include the following.

1. Configure port

By default, GitLab’s port is 80. If you need to modify the port number, you can do so with the following command:

sudo vi /etc/gitlab/gitlab.rb

Find the following line:

# gitlab_workhorse['listen_network'] = "tcp"
# gitlab_workhorse['listen_addr'] = "localhost:8181"

Uncomment and change 8181 to the port you need.

2. Modify the domain name

After configuring the port, we also need to modify the domain name of GitLab. Enter the following command:

sudo vi /etc/gitlab/gitlab.rb

Find the following line:

external_url 'http://gitlab.example.com'

Change gitlab.example.com to the domain name or IP address you need.

3. Restart GitLab

After modifying the above configurations, we need to restart GitLab for these configurations to take effect. Enter the following command:

sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

3. Create an administrator account

After the installation is completed and GitLab is restarted, we need to create an administrator account. Open the browser, enter the domain name or IP address you configured above, and enter the GitLab login interface.

Click the "Register" button, enter your name, email address, password and other information, and then click the "Register" button.

After the registration is completed, we need to set the account as an administrator account. Find and click on the "Administrator" avatar and click on "Manage Area". In the "Access" section, set "Permissions" to "Administrator" and click the "Save Changes" button.

In this way, we create an administrator account.

4. Create a project and perform code management

Now, we have successfully set up a GitLab node and created an administrator account. Next, we can create a Git project and use GitLab for code management.

First, we need to enter the management area of ​​GitLab and create a new project. In the "Settings" page of a new project, you can set a project name, description, and visibility of the project.

After the creation is completed, we can use GitLab for code management. Open the terminal and enter the following command:

git clone ssh://<your-gitlab-server>/<your-username>/<your-repo>.git
cd <your-repo>
echo "# Hello World" > README.md
git add README.md
git commit -m "add README"
git push -u origin master

The above command will pull the code from the GitLab server, modify the README.md file, and submit the modification. Finally, push the modified code to the GitLab server.

In general, it is not complicated to set up GitLab nodes and manage code. It only takes a few simple steps to complete. Of course, if you have more complex usage requirements, you can check GitLab's official documentation to learn more functions and operations.
