一、git、github、gitlab的区别

Git是版本控制系统，Github是在线的基于Git的代码托管服务。

GitHub是2008年由Ruby on Rails编写而成。GitHub同时提供付费账户和免费账户。这两种账户都可以创建公开的代码仓库，只有付费账户可以创建私有的代码仓库。

Gitlab解决了这个问题, 可以在上面创建免费的私人repo。

二、gitlab server搭建过程

[root@vm1 ~]#  yum install -y curl openssh-server openssh-clients postfix cronie policycoreutils-python
//10.x以后开始依赖policycoreutils-python
[root@vm1 ~]# systemctl start postfix
[root@vm1 ~]# systemctl enable postfix

gitlab的下载地址：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

安装gitlab：

[root@vm1 ~]# rpm -ivh gitlab-ce-10.7.2-ce.0.el7.x86_64.rpm 
warning: gitlab-ce-10.7.2-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

[root@vm1 ~]#

gitlab的配置文件 /etc/gitlab/gitlab.rb，编辑如下：

[root@vm1 ~]# vim /etc/gitlab/gitlab.rb 
[root@vm1 ~]# grep "^external_url" /etc/gitlab/gitlab.rb
external_url 'http://192.168.60.119'   绑定监听的域名或IP（企业中最好是域名)
[root@vm1 ~]#

使用gitlab-ctl reconfigure 自动配置，并安装数据库，初始化信息，如下所示(第一次使用配置时间较长)：

[root@vm1 ~]# gitlab-ctl reconfigure   <生成 /var/opt/gitlab/ 各种子配置, 该命令建议仅在初始化时使用一次> 
.....

注: 第一次初始化后会产生当前gitlab的配置文件 /var/opt/gitlab/gitlab-rails/etc/gitlab.yml ，在后期维护的过程中尽量配置 /var/opt/gitlab/gitlab-rails/etc/gitlab.yml 文件，然后gitlab-ctl restart 即可生效新的配置；如果没有必要不建议做第二次初始化。

使用gitlab-ctl start 启动gitlab服务，如下所示：

[root@vm1 ~]# gitlab-ctl start
ok: run: gitaly: (pid 22896) 2922s
ok: run: gitlab-monitor: (pid 22914) 2921s

[root@vm1 ~]#

修改配置文件，添加smtp邮件功能

[root@vm1 ~]# vim /etc/gitlab/gitlab.rb
[root@vm1 ~]# grep -P "^[^#].*smtp_|user_email|gitlab_email" /etc/gitlab/gitlab.rb
gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = 'username@domain.cn'
gitlab_rails['gitlab_email_display_name'] = 'Admin'
gitlab_rails['gitlab_email_reply_to'] = 'usernamei@domain.cn'
gitlab_rails['gitlab_email_subject_suffix'] = '[gitlab]'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.exmail.qq.com"
gitlab_rails['smtp_port'] = 25 
gitlab_rails['smtp_user_name'] = "username@domain.cn"
gitlab_rails['smtp_password'] = "password"
gitlab_rails['smtp_domain'] = "domain.cn"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = false
user['git_user_email'] = "username@domain.cn"

[root@vm1 ~]# gitlab-ctl reconfigure

使用gitlab-rails console命令进行发送邮件测试，如下所示：

[root@vm1 ~]# gitlab-rails console 
Loading production environment (Rails 4.2.10)
irb(main):001:0>  Notify.test_email('user@destination.com', 'Message Subject', 'Message Body').deliver_now

irb(main):002:0>quit
[root@vm1 ~]#

三、gitlab的使用

在浏览器中输入 http://192.168.60.119/ ，然后 change password: ，并使用root用户登录即可 (后续动作根据提示操作)

修改密码也可以：gitlab-rails console production

irb(main):001:0> user = User.where(id: 1).first // id为1的是超级管理员

irb(main):002:0>user.password = 'yourpassword' // 密码必须至少8个字符

irb(main):003:0>user.save! // 如没有问题返回true

exit // 退出

如果需要手工修改nginx的port ，可以在gitlab.rb中设置 nginx['listen_port'] = 8000 ，然后再次 gitlab-ctl reconfigure即可

登录gitlab 如下所示：

gitlab搭建与基本使用【转】_html_02

创建 group ，组名为plat-sp ,如下所示:

gitlab搭建与基本使用【转】_git_03

gitlab搭建与基本使用【转】_git_04

去掉用户的自动注册功能：

admin are -> settings -> Sign-up Restrictions 去掉钩钩，然后拉到最下面保存，重新登录

gitlab搭建与基本使用【转】_DevOps_05

创建用户Tompson如下所示：

gitlab搭建与基本使用【转】_nginx_06

同样的方法，再创建Eric 、Hellen 用户。用户添加完毕后，gitlab会给用户发一封修改密码的邮件，各用户需要登录自己的邮箱，并点击相关的链接，设置新密码。

将用户添加到组中，并指定Tompson为本组的owner：

gitlab搭建与基本使用【转】_nginx_07

同样的方法将用户Eric、Hellen也添加到组中，并指定他们为Developer：

gitlab搭建与基本使用【转】_git_08

使用Tompson用户的身份与密码登录到gitlab界面中，并创建Project ，如下所示：

gitlab搭建与基本使用【转】_nginx_09

指定项目的存储路径和项目名称，如下所示

gitlab搭建与基本使用【转】_DevOps_10

gitlab搭建与基本使用【转】_DevOps_11

为项目创建Dev分支，如下所示：

gitlab搭建与基本使用【转】_git_12

gitlab搭建与基本使用【转】_开发人员_13

在 client 上添加Tompson的用户：

[root@vm2 ~]# useradd Tompson
[root@vm2 ~]# useradd Eric
[root@vm2 ~]# useradd Hellen
[root@vm2 ~]# su - Tompson
[Tompson@vm2 ~]$ ssh-keygen -C Tompson@domain.cn

将Tompson的公钥复制到gitlab中：使用Tompson用户的身份与密码登录到gitlab界面中，然后在ssh-key中添加相关的key ，如下所示：

gitlab搭建与基本使用【转】_nginx_14

gitlab搭建与基本使用【转】_git_15

为Tompson用户配置git ，如下所示：

[Tompson@vm2 ~]$ git config --global user.email "Tompson@domain.cn"
[Tompson@vm2 ~]$ git config --global user.name "Tompson"

[Tompson@vm2 ~]$ git clone git@192.168.60.119:plat-sp/chathall.git
