How to deploy GitLab on a Linux server

As a modern code management tool, GitLab is used more and more widely. In team collaboration, using GitLab to manage code is a convenient and efficient choice. This article will introduce how to deploy GitLab on a Linux server.

1. Confirm the environment

First, you need to confirm that your server system is 64-bit and has at least 2GB of memory and 2 CPUs. Ideally, the server should also have 80GB of disk space.

Next, select the appropriate installation method according to the server's operating system. Here we take Ubuntu as an example to introduce how to install GitLab.

2. Install necessary software

In the Ubuntu system, you need to install the necessary software packages. Enter the following command in the terminal to install:

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

Postfix is ​​a mail server that can be used to handle GitLab email notifications.

3. Add GitLab software library

In order to install GitLab, you need to add the GitLab software library. Enter the following command in the terminal:

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

4. Install GitLab

After adding the software repository, you can start installing GitLab. Enter the following command in the terminal:

sudo apt-get install gitlab-ee

The installation program will start automatically. Follow the program prompts to configure. Of course, you can modify the default configuration according to your own needs. This process may take a while, but once the installation is complete, your GitLab will be configured and ready to run.

5. Start GitLab

After the installation is complete, you can use the following command to start GitLab:

sudo gitlab-ctl reconfigure
sudo gitlab-ctl start

6. Access GitLab

Now, you can access GitLab in your browser. Enter the IP address or domain name of the server, then enter the username (admin) and password (gitlab123) on the page to log in successfully.

7. Configuring GitLab

After successful installation, you need to configure GitLab to meet your personalized needs. Some important settings are as follows:

• Change administrator password

After logging in, you can change the password on the personal account page.

• Create new users and authorize

In the left panel, click "Users" to view the user list. Click the "plus sign" to add a new user. Administrators can view and modify user permissions by clicking on the Users link.

• Configure SMTP service

GitLab requires the SMTP service library to send emails. You can use an external mail service or install a mail server locally. Select email notification in employee settings, and then enter SMTP server related information.

• Use a self-signed SSL certificate

When accessing a trusted HTTPS website in a browser, you need to use an SSL certificate. GitLab uses a self-signed certificate by default for establishing HTTPS connections. You can use a self-signed certificate or purchase a certificate from a third-party merchant.

• Configuring LDAP

If you use LDAP as your user authentication system, you can configure it in GitLab. In the left panel, click the "LDAP" option, and then enter the relevant information of the LDAP server.

8. Summary

So far, you have completed the deployment of a basic GitLab server. With GitLab's powerful team collaboration and code management capabilities, your team can develop more efficiently. Of course, this is just a brief introduction to the installation process of GitLab. If you want to use more functions of GitLab, you can view more detailed documents and tutorials on the official website.
