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
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
[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
.....
使用gitlab-ctl start 启动gitlab服务，如下所示：
[root@vm1 ~]# gitlab-ctl start

ok: run: gitlab-monitor: (pid 22914) 2921s

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['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.exmail.qq.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "[email protected]"
gitlab_rails['smtp_password'] = "password"
gitlab_rails['smtp_domain'] = "domain.cn"
