Dependencies

Run to the below command to install the GitLab dependencies.

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

When prompted, select Internet Site when configuring Postfix.

Enter the FQDN.

Installing GitLab

GitLab provides a bash script that add their repository for you. Just download it and run it.

cd /tmp
curl -LO https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh
sudo bash /tmp/script.deb.sh

Now you can install the GitLab package using the apt-get package manager.

sudo apt-get install gitlab-ce

Configuring GitLab

You need to first edit the configuration file.

sudo vim /etc/gitlab/gitlab.rb

I added the following line to define my primary hostname and URL.

external_url 'https://repo.dummydomains.org.uk'

I also enabled letsencrypt. If you do, make sure the DNS is setup already.

letsencrypt['enable'] = true
letsencrypt['contact_emails'] = ['[email protected]']
letsencrypt['auto_renew'] = true
letsencrypt['auto_renew_hour'] = "3"
letsencrypt['auto_renew_minute'] = "30"
letsencrypt['auto_renew_day_of_month'] = "*/7"

This will auto-renew at 3:30 AM every seventh day. Now run the below command to bring about your changes.

sudo gitlab-ctl reconfigure

If all was successful, you should see gitlab Reconfigured! on the last line of output.

Browse to the URL and change your password.

Then log in with the root user and the password you just created.

GitLab is now installed!

It’s time to start configuring it! You may want to look at preventing people signing up.
