In this article, we will introduce how to install GitLab on CentOS using a one-click script.

1. Preparation before installation

Before you start installing GitLab, you need to install some necessary software packages and set the correct time zone. Enter the following command:

yum -y install curl policycoreutils openssh-server openssh-clients

2. Install GitLab

We can install GitLab through the following script:

curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash
sudo EXTERNAL_URL="http://gitlab.example.com" yum install -y gitlab-ee

The above command will download the installation package from the GitLab official website, The installation package will be automatically added to the system's software sources. The EXTERNAL_URL variable here specifies the access URL address of GitLab. This variable needs to be set according to the actual situation.
