Manually Deploying GitLab (CentOS 7.2)

Overview

The best practices for Huawei Cloud ECS guide you through the manual deployment of GitLab on a Linux ECS. GitLab is an open-source version management system that uses Git as the code management tool. The CentOS 7.2 64bit OS is used as an example in this section.

Prerequisites

• The memory of the target ECS is greater than or equal to 4 GB.
• The rule listed in the following table has been added to the security group which the target ECS belongs to. For details, see Adding a Security Group Rule.

  Table 1 Security group rule

  Direction	Priority	Action	Type	Protocol & Port	Source Address
  Inbound	1	Allow	IPv4	TCP: 80	0.0.0.0/0

Procedure

1. Install the dependency package.
   1. Log in to the ECS.
   2. The image source has been updated to a Huawei Cloud image source. For details, see How Can I Use an Automated Tool to Configure a Huawei Cloud Image Source (x86_64 and Arm)? This facilitates obtaining and updating the system and software.
   3. Run the following command to install the dependency packages:

      sudo yum install -y curl policycoreutils-python openssh-server

   4. Run the following commands to configure automatic SSH enabling upon ECS startup and start SSH:

      sudo systemctl enable sshd

      sudo systemctl start sshd

2. Install Postfix to send emails.
   1. Run the following command to install Postfix:

      sudo yum install postfix

   2. Run the following commands to configure automatic Postfix enabling upon ECS startup and start Postfix:

      sudo systemctl enable postfix

      sudo systemctl start postfix

3. Add the GitLab repository and install the software package.
   1. Run the following command to add the GitLab repository:

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

   2. Run the following command to install GitLab:

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

      Set EXTERNAL_URL to the IP address of the GitLab server, which can be the public IP address of the server or the domain name.

      

      • After the command is executed, you can view the software download speed and the estimated download completion time in the command output.

      If information similar to the following is displayed, GitLab has been installed:

      Thank you for installing GitLab!

4. Test the GitLab deployment.
   1. Enter http://Server IP address in the address bar. If the following page is displayed, GitLab has been set up.

      

   2. Change the password upon your first login. Then, enter the new password to log in.
