We will walk you through the step-by-step process of installing GitLab on Linux. Whether you are an Ubuntu or CentOS user, this guide has got you covered! GitLab is a powerful web-based Git repository manager that provides a complete DevOps platform for managing code repositories, continuous integration/continuous deployment (CI/CD), issue tracking, and more.
Section 1: Preparing the Environment
Before we begin with the installation of GitLab on Linux, it’s important to ensure that your system meets the necessary requirements. This section will cover the prerequisites for both Ubuntu 22.04 and CentOS 8.
For Ubuntu 22.04:
Update the package lists:
sudo apt updateInstall the necessary dependencies:
sudo apt install -y curl openssh-server ca-certificates postfix
Add the GitLab package repository and install GitLab on Linux:
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh | sudo bash
sudo EXTERNAL_URL="http://your-domain-name.com" apt install gitlab-eeFor CentOS 8:
Update the system packages:
sudo dnf updateInstall the necessary dependencies:
sudo dnf install -y curl policycoreutils-python-utilsAdd the GitLab package repository and install GitLab on Linux:
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash
sudo EXTERNAL_URL="http://your-domain-name.com" dnf install gitlab-eeSection 2: Configuring GitLab GitLab on Linux
Once GitLab is successfully installed, we need to configure a few settings to ensure optimal performance. This section will cover essential configurations, including setting up email notifications, configuring SSL certificates, and adjusting performance-related settings.
Open the GitLab configuration file for editing:
sudo nano /etc/gitlab/gitlab.rbCustomize the settings according to your requirements. For example, to configure email notifications, find the following lines and update them:
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.example.com"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "your-email@example.com"
gitlab_rails['smtp_password'] = "your-email-password"
gitlab_rails['smtp_domain'] = "example.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = trueSave the changes and reconfigure GitLab:
sudo gitlab-ctl reconfigureSection 3: Accessing GitLab
After the installation and configuration steps, we will show you how to access GitLab through a web browser. Additionally, we will guide you through the initial setup process, including creating an admin account and exploring essential GitLab features.
Open your web browser and navigate to http://your-domain-name.com.
If you have installed GitLab but don’t have the credentials to log in, you can follow the steps below to reset the administrator password:
Open a terminal or command prompt on the machine where GitLab is installed.
Run the following command to start a GitLab Rails console:
sudo gitlab-rails consoleOnce the Rails console starts, enter the following command to reset the password:
user = User.where(id: 1).first
user.password = 'new_password'
user.password_confirmation = 'new_password'
user.save!Replace 'new_password' with the desired password you want to set.
Exit the Rails console by entering:
exitRestart GitLab to apply the changes:
sudo gitlab-ctl restart
sudo gitlab-ctl startAfter following these steps, you should be able to log in to your GitLab instance using the new password you set for the administrator account.
Section 4: Advanced Configuration (Optional)
For advanced configuration options, refer to the GitLab documentation (https://docs.gitlab.com/).
