Introduction

When talking about online git services, a popular option is GitHub. But for privacy, flexibility and/or network speed purposes, you might want to deploy a git service on a cloud machine under your control. In this case, you can use GitLab Community Edition (CE) to reach your goal.

GitLab can be installed on Ubuntu, Debian, CentOS, RHEL, Scientific Linux, and Oracle Linux; other *nix distributions are not officially supported. In this tutorial, I will show you how to install a GitLab Community Edition (CE) omnibus RPM package on An ITWeb.Services CentOS 6 x64 server.

Prerequisites

Before moving on, you need to:

  • Deploy a CentOS 6 x64 server instance. None of the 32-bit operating systems are supported.

    • https://www.itweb.services/tutorials/linux-guides/hot-backups-with-percona-xtrabackup-on-the-one-click-wordpress-app”>this article for details.

  • Submit a support ticket to cancel IT Web Services’s default block on SMTP port 25, if you want to use your own VPS to send emails.

    • https://www.itweb.services/tutorials/linux-guides/how-to-change-your-hostname-on-centos”>this article.

  • Bind a domain to your server, otherwise you will have to access your git repos by the IP address.

    • Step one: Install and configure the necessary dependencies

    sudo yum install curl openssh-server postfix cronie
sudo service postfix start
sudo chkconfig postfix on
sudo lokkit -s http -s ssh

    Step two: Get and install the GitLab CE omnibus package

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

    Step three: Configure and start GitLab

    sudo gitlab-ctl reconfigure

    Step four: Log in from your browser and change your password

    Log in from your browser with the following credentials:

    username: root
password: 5iveL!fe

    After you log in, the system will ask you to change your password immediately. You need to change it and log in again.

    Step five: More configuration changes

    GitLab has lots of features that can be tuned.

    As a starter, you need to configure the external URL in your terminal if you have not set up the host name, FQDN, and domain binding properly:

    sudo vi /etc/gitlab/gitlab.rb

    Find the following line:

    external_url 'itweb.services.guest'

    Replace it with:

    external_url 'http://[YourIP]/'

    Save and exit. Then input:

    sudo gitlab-ctl reconfigure

    Other features can be configured according to your specific circumstance. Remember to run the command sudo gitlab-ctl reconfigure after you make any configuration changes.

    Note: Before you configure email-related features properly, all newly-registered users (except for root) will not be able to log in because their email addresses have not been confirmed. You can log in as root and confirm them manually.

    The setup is complete. For further reading, visit the GitLab official website.
