Git Engineering Development Practice (VII)--GitLab Service Building

Operating System: RHEL 7.3 WorkStation

1. Introduction to GitLab 1. Introduction to GitLab

GitLab is an open source version management system developed using Ruby on Rails. It is an open source git repository management software that integrates code hosting, testing, and deployment. It can be accessed through a web interface for public or private projects. GitLab has the ability to browse code, manage bugs and comments, manage team access to repositories, easily browse committed versions, and provide a file history repository, making it a popular R & D version control system.

Git: Native version control system tool.

Github: The world's largest online code hosting repository, https://github.com.

GitLab: Support for online code hosting, support for private code hosting server deployment.

2. Continuous integration function of GitLab

Gitlab-CI stands for GitLab Continuous Integration.

Since version 8.0 of Gitlab, Gitlab has fully integrated Gitlab-CI and is enabled by default for all projects.

Continuous integration functionality is provided in GitLab 8.0+, and there is a concept of Runners in GitLab.

There are three types of runners.

1)Local Runner

2)Runner on a regular server

3)Docker-based Runner

3. Service Composition of Gitlab

Nginx: Static web server

gitlab-shell: Used to process Git commands and modify the list of authorized keys

gitlab-workhorse: lightweight reverse proxy server

logrotate: log file management tool

postgresql: database

redis: cache database

sidekiq: Used to execute queue tasks in the background (asynchronous execution)

unicorn: An HTTP server for Rack applications on which GitLab Rails applications are hosted

4. GitLab Common Commands

Gitlab commands are divided into two parts: general commands and service management commands

Syntax: gitlab-ctl command parameters

General Command:

The command parameters are as follows:

Help: Help

reconfigure: Reload configuration after modifying configuration file

show-config: View all service profile information

uninstall: uninstall software

cleanse: delete gitlab data and start again from scratch

Service Management Command:

start: Start all services

stop: Close all services

restart: Restart all services

status: View all service status

tail: View log information

service-list: List all startup services

Graceful-kill: stop a service smoothly

Second, GitLab installation configuration 1, installation configuration GitLab related dependencies

Install dependencies, configure firewall open HTTP and SSH services

sudo yum install -y curl policycoreutils-python openssh-serversudo systemctl enable sshdsudo systemctl start sshdsudo firewall-cmd --permanent --add-service=httpsudo systemctl reload firewalld

If you want to use Postfix to send notification messages, select 'Internet Site' during Postfix installation.

sudo yum install postfixsudo systemctl enable postfixsudo systemctl start postfix

You can also configure an external SMTP server after GitLab has been successfully installed.

2. Add GitLab package repository

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

3. Install GitLab

sudo yum install gitlab-ce-10.7.3-ce.0.el7.x86_64

You need to set the domain name of gitlab, or you can use the ip address.

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

After completion, modify the file/etc/gitlab/gitlab.rb to set the access url

4. GitLab configuration

sudo gitlab-ctl reconfigure

Initial configuration of GitLab will be slow, wait patiently.

After loading, start Gitlab, which uses ports 80, 8080, and 9090 by default.

Restart gitlab service:

sudo gitlab-ctl restart

The first time you access the web interface after installation, you will be asked to reset the new password for the root account.

Log in to the server with root privileges and start the Ruby on Rails console

gitlab-rails console production

[root@localhost ~]# gitlab-rails console productionLoading production environment (Rails 4.2.8)irb(main):001:0> irb(main): 001:0> user = User.where(id: 1).first=> #irb(main):002:0>user.password = 'secret_pass' irb (main):002:0>user.password_confirmation = 'secret_pass' irb (main): 002:0>user.save5, Register User

Register a new user:

Set information for newly registered users:

Generate SSH public key:

ssh-keygen -t rsa -C "user@qq.com" -b 4096

The SSH public key generated is stored in the ~/.ssh/id_rsa.pub file.

Copy all the contents of id_rsa.pub file to Key edit box:

6. Create a new group

7. New construction
