22.4 GITLAB
在讲完搭建GIT服务器之后，我们都知道这并不完美，只适用于开发人员较少的公司。所以寻求一种更好的解决方案，国内有CODING、码云等都可以作为选择，这样可以不用自己维护；另外一种比较好的方法就是搭建GITLAB服务器。
官方网站：https://about.gitlab.com/
安装文档：https://about.gitlab.com/installation/#centos-7 （针对的是企业版ee）
我们要使用的是社区版本ce，不管是哪个版本，都要求服务器内存不低于4G。
安装gitlab
- 编辑repo文件：
[root@localhost ~]# vim /etc/yum.repos.d/gitlab.repo //写入下面内容
[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1- 安装gitlab：
[root@localhost ~]# yum install -y gitlab-ce
[root@localhost ~]# gitlab-ctl reconfigure //自动配置gitlab
Running handlers:
Running handlers complete
Chef Client finished, 432/614 resources updated in 05 minutes 39 seconds
gitlab Reconfigured!上面配置过程会花费一些时间，因为gitlab会将它启动所需要的服务全部配置好后打开
[root@localhost ~]# netstat -lntp

gitlab-ctl stop 关闭gitlab服务
gitlab-ctl restart 重启gitlab服务安装完gitlab之后，直接在浏览器访问gitlab，输入服务器ip即可（访问之前打开80端口）
打开之后默认让你更改密码，更改完密码让你登录，默认用户名是root
登录进来后，可以新建项目、组、用户和配置gitlab
在实际使用过程中，可以配置域名和服务器代理，这样就不用直接输入IP登录了。
- 新建组（group）：
- 新建项目（project）：
提示没有任何的ssh key，之前Git有配置过ssh key，gitlab也需要配置ssh key。
[root@localhost ~]# ssh-keygen //生成密钥
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): //直接按Enter键
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): //直接按Enter键（要用密码可以输入密码）
Enter same passphrase again: //直接按Enter键
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:

- 新增用户（user）：
在admin area里面新增用户。我这里稍微有点奇怪，这个图标没显示出来，是个小扳手的图标，不过不影响，鼠标点在这里会有提示，点进来就可以新增用户了。
- 编辑用户：
直接点击Edit，编辑用户，设置密码。之后新用户使用密码登录之后第一次就会让你设置新密码，然后使用新密码在登录一次。新用户登录之后也可以创建自己的组和项目。
另外，gitlab的操作和github有些类似，具体参考这里：https://www.cnyunwei.cc/archives/1204 。
gitlab的备份和恢复
- gitlab备份：
[root@localhost ~]# gitlab-rake gitlab:backup:create //gitlab备份，会备份项目、组、用户和代码，数据量比较大的话会耗费较长时间

1536592589_2018_09_10_11.2.3_gitlab_backup.tar - gitlab的恢复：
gitlab的恢复必须要保证gitlab的版本一致，否则会出现问题
先停两个服务，目的是让数据不在发生变更（只需要停这两个）：
[root@localhost ~]# gitlab-ctl stop unicorn ; gitlab-ctl stop sidekiq //unicorn是rubby相关的webserver，sidekiq是rubby相关的消息队列
ok: down: unicorn: 0s, normally up
ok: down: sidekiq: 0s, normally up
开始恢复：
[root@localhost ~]# gitlab-rake gitlab:backup:restore BACKUP=1536592589_2018_09_10_11.2.3 //gitlab恢复，BACKUP后面跟要恢复文件的前缀，数据量大恢复也会花费很长时间
