Detailed explanation of the installation of GitLab 7 under the CentOS 7 operating system

CentOS GitLab 7 Installation

GitLab is a convenient Git project management tool. Through GitLab, we can easily manage code versions, collaborative development and project management. This article introduces the installation process of GitLab 7 under the CentOS 7 operating system.

1. Preparation

Before starting to install GitLab, you need to ensure that the following software has been installed and configured on the system:

• Git
• Ruby
• RubyGems
• GCC version 4.8 or higher
• Several library files that GitLab depends on

If you If all the above software has been installed on your system, you can skip this step directly. Otherwise, you need to use the following commands to install these software:

Install Git:

yum install git

Install Ruby:

yum install ruby

Install RubyGems:

yum install rubygems

Install GCC version 4.8 or higher:

yum install gcc48

Then add the path of GCC to the environment variable:

export CC=/usr/bin/gcc-4.8

Install several library files that GitLab depends on:

yum install readline-devel zlib-devel libyaml-devel libffi-devel openssl-devel sqlite-devel

2. Install GitLab

At this point, we are ready to start installing GitLab. The following are the installation steps:

First, download GitLab:

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-7.9.2-ce.0.el7.x86_64.rpm

The last number is the GitLab version number, which you can modify according to the actual situation. Next, use the following command to install GitLab:

rpm -i gitlab-ce-7.9.2-ce.0.el7.x86_64.rpm

After the installation is complete, we need to perform some configurations on GitLab.

3. Configuring GitLab

Before installing GitLab, we need to do some configuration on GitLab to ensure that it can work properly. The following are the configuration steps:

First, edit the /etc/gitlab/gitlab.rb file:

vi /etc/gitlab/gitlab.rb

Then find the following two lines and uncomment them:

external_url 'http://gitlab.example.com'
nginx['enable'] = true

The above code will enable GitLab's nginx web server and bind it to the URL "http://gitlab.example.com".

Next, use the following command to reconfigure GitLab:

gitlab-ctl reconfigure

This command will cause GitLab to reload the configuration file.

Now you can access GitLab through your browser and configure it the way you want.

4. Using GitLab

Now, you have successfully installed GitLab and completed some necessary configurations. Next, we can use GitLab to manage code, collaborate on development, and manage projects. The following are some commonly used GitLab commands:

• gitlab-ctl start: Start the GitLab service.
• gitlab-ctl status: Check the running status of GitLab service.
• gitlab-ctl stop: Stop the GitLab service.

In addition to the above commands, you can also manage code, collaborate on development, and manage projects through the GitLab web interface. In addition, you can customize GitLab's functionality and interface to suit different project needs.
