The first step is to upgrade your system packages:

sudo apt-get update && sudo apt-get upgrade -y

Step 2: Install Required Dependencies

Install some required dependencies for GitLab:

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

For Postfix Installation. Choose the “Internet Site” option and enter your domain name.

Add the GitLab package repository to your system.

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

Now install GitLab:

sudo apt-get install gitlab-ee

This will install the GitLab Community Edition on your system.

Step 4: Configure GitLab

Open the GitLab configuration:

sudo nano /etc/gitlab/gitlab.rb

Find this lines in the config file:

# external_url 'http://gitlab.example.com'
# letsencrypt['contact_emails'] = ['[email protected]']

Uncomment the first line and replace gitlab.example.com with your domain name:

external_url 'https://your-domain-name.com'

Uncomment the second line and replace [email protected] with your email address:

letsencrypt['contact_emails'] = ['[email protected]']

Save and close the file.

Step 5: Configure Let’s Encrypt SSL

To enable Let’s Encrypt SSL for GitLab:

sudo gitlab-ctl reconfigure

This command will generate a Let’s Encrypt SSL certificate for your domain name and configure GitLab to use it.
