How to Install GitLab Server on RHEL/CentOS 7

Install Gitlab Server on RHEL CentOS 7.6

GitLab is an open-source web-based git repository manager providing wiki, issue-tracking and CI/CD (Continuous Integration/Common Deployment). GitLab available in two editions, CE (Community Edition) and EE (Enterprise Edition). The GitLab CE has limited features while the GitLab EE is the commercial product and loaded with many additional features. Both GitLab CE & EE editions are available to download, however, the GitLab EE will provides same features as GitLab CE unless one acquires a license from GitLab.

In this article, we will install the GitLab EE on our Red Hat Enterprise Linux (RHEL) / CentOS 7.6 Server.

We have configured a virtual machine with following specification.

Hostname - gitlab-server.itlab.com
IP Address - 192.168.116.128/24
CPU - 3.2 Ghz (2 Cores)

Install Gitlab Server on RHEL CentOS 7.6

Installing GitLab Server on RHEL/CentOS 7:

Connect to gitlab-server.itlab.com using ssh, and install required packages using yum command.

# yum install -y curl policycoreutils-python

It also requires postfix and openssh-server packages. But both of them are already installed with minimal installation of Red Hat Enterprise Linux (RHEL) or CentOS 7.6.

Allow the http service through Linux firewall.

# firewall-cmd --permanent --add-service=http
success
# firewall-cmd --reload
success

Add GitLab package repository to yum.

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