Configure gitlab

1. Install the prerequisite software

[root@gitlab ~]# yum  -y install curl policycoreutils openssh-server openssh-clients postfix 

2. Download the gitlab installation package

[root@gitlab ~]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.2.2-ce.0.el7.x86_64.rpm(清华源）
[root@gitlab ~]#  yum -y install gitlab-ce-10.2.2-ce.0.el7.x86_64.rpm

3. Modify the configuration file, specify the ip address

[root@gitlab ~]# vim /etc/gitlab/gitlab.rb 
修改：
external_url 'http://192.168.1.20‘

5. Configure to start gitlab

Gitlab web management

1. Log in to gitlab

Set the password first, 12345678, and reconfirm 12345678

Username: root

Password: 12345678

2. Cancel the login page registration function

Log in to gitlab >> admin area (small wrench diagram on the top menu bar >> Settings on the left panel >> Sign-up Restrictions >> Uncheck sign-up enabled >> Drop down and select save

3. Modify the login welcome page

Log in to gitlab >> admin area >> Appearance >> fill in the administrator’s contact information and logo >> save

Case

Project creation

1. Project creation process

(1) Create a group (group)

登录gitlab >> admin area >> new group

(2) Create user (user)

Log in to gitlab >> admin area >> new user >> add username, email >> create >> edit >> modify password

(3) Create a project

Log in to gitlab >> admin area >> new project >> pay attention to select group

Groups in Gitlab have three access rights to projects:

Authority	Explanation
Private	Only group members can see
Internal	As long as the logged in user can see
Public	Everyone can see

(4) Add members to the group

Add wangwu to accp,

Gitlab users have five permissions in the group:

Authority	Explanation
Guest	Can create issues, post comments, and cannot read and write the repository
Reporter	Code can be cloned but not submitted. Test and product manager can grant this permission
Developer	Can clone code, develop, submit, push, developers can give this permission
Master	You can create projects, add tags, protect branches, add project members, and edit projects. The core RD leader can grant this permission
Owner	You can set project access permissions-Visibility Level, delete projects, migrate projects, management team members, and the development team leader can grant this permission
