Install GitLab CE to Centos7

1. Install and configure the necessary dependencies
   On CentOS 7, the commands below will also open HTTP and SSH access in the system firewall.

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

Next, install Postfix to send notification emails. If you want to use another solution to send emails please skip this step and configure an external SMTP server after GitLab has been installed.

sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix

During Postfix installation a configuration screen may appear. Select ‘Internet Site’ and press enter. Use your server’s external DNS for ‘mail name’ and press enter. If additional screens appear, continue to press enter to accept the defaults.

2. Add the GitLab package repository and install the package
   Add the GitLab package repository.

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

Next, install the GitLab package. Change http://gitlab.example.com to the URL at which you want to access your GitLab instance. Installation will automatically configure and start GitLab at that URL. HTTPS requires additional configuration after installation.

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

3. Browse to the hostname and login
   On your first visit, you’ll be redirected to a password reset screen. Provide the password for the initial administrator account and you will be redirected back to the login screen. Use the default account’s username root to login.

See our documentation for detailed instructions on installing and configuration.

4. Set up your communication preferences
   Visit our email subscription preference center to let us know when to communicate with you. We have an explicit email opt-in policy so you have complete control over what and how often we send you emails.

Twice a month, we send out the GitLab news you need to know, including new features, integrations, docs, and behind the scenes stories from our dev teams. For critical security updates related to bugs and system performance, sign up for our dedicated security newsletter.
