How to install GitLab server under CentOS 7

GitLab is a code hosting and version control platform based on Git. It not only provides a powerful code collaboration platform, but also integrates CI/CD functions, so that enterprise users can achieve efficient software development, continuous integration, and continuous delivery. This article will introduce how to install GitLab server in CentOS 7.

Step One: Install Necessary Dependencies

First, we want to install some necessary dependencies to be able to compile and install the package on our system. Here are the commands to install the required dependencies:

sudo yum install curl policycoreutils openssh-server openssh-clients 
sudo systemctl enable sshd
sudo systemctl start sshd
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo systemctl reload firewalld

Step 2: Add GitLab repository and install GitLab

Since GitLab is not in the CentOS software repository, we need to add the GitLab repository manually. The following is the command to add the repository:

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

Next, use the following command to install GitLab:

sudo EXTERNAL_URL="http://gitlab.example.com" yum install -y gitlab-ce

In the above command, you need to http://gitlab.example.com Replace with the hostname or IP address of your GitLab server.

Step 3: Configure GitLab

After installing GitLab, you need to perform some basic configurations, such as configuring SMTP and accounts and passwords. You can configure it by editing the following file:

sudo vi /etc/gitlab/gitlab.rb

When configuring SMTP, you can use the following configuration:

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "yourname@qq.com"
gitlab_rails['smtp_password'] = "yourpassword"
gitlab_rails['smtp_domain'] = "smtp.qq.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true

Please note that in the above configuration, smtp_address needs to be replaced For your SMTP server address, replace smtp_user_name and smtp_password with your SMTP account and password.

After committing the changes, use the following command to reconfigure GitLab:

sudo gitlab-ctl reconfigure

Step 4: Access GitLab

Now, you can access GitLab through your browser. Simply enter your server IP address or hostname in the address bar to open the GitLab interface. You can then log in with your administrator account and start using GitLab.

Summary

Installing GitLab server is not complicated, just follow the above steps one by one. Whether you are a large enterprise or an independent developer, GitLab as a code collaboration and version control platform provides you with powerful tools to support key business processes and flexible development methods.
