[gitlab_gitlab-ce]
name=gitlab_gitlab-ce
baseurl=https://packages.gitlab.com/gitlab/gitlab-ce/el/8/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
gpgkey=https://packages.gitlab.com/gitlab/gitlab-ce/gpgkey
       https://packages.gitlab.com/gitlab/gitlab-ce/gpgkey/gitlab-gitlab-ce-3D645A26AB9FBD22.pub.gpg
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

[gitlab_gitlab-ce-source]

Save the file, close it and update the system

sudo dnf update -y

Step 4. Install GitLab

Now, when the repo is added we can install GitLab with the following command:

sudo dnf install gitlab-ce -y

After successfull installation start the GitLab service:

sudo gitlab-ctl start

To check the GitLab ports execute the following command:

netstat -tunlp | grep gitlab

You should receive the following output:

[root@host]# netstat -tunlp | grep gitlab
tcp6       0      0 ::1:8153                :::*                    LISTEN      53473/gitlab-kas

Step 5. Access GitLab with Domain

To access the GitLab in the browser via domain name, you need to configure it in the following file: /etc/gitlab/gitlab.rb.

Open it with your favorite browser and edit the following lines by entering your domain name and setting your strong root password:

external_url 'http://

YourDomainHere

'

gitlab_rails['initial_root_password'] = '

YourStrongPasswordHere

'

Save the file, close it and execute the following command:

gitlab-ctl reconfigure

After reconfiguring the application you can access GitLab at http://YourDomain using the root as username and your strong password you set above.
