配置文件可以参考：
https://blog.csdn.net/peterxiaoq/article/details/73330302
如果socket权限有问题，可以使用端口也ok
upstream gitlab {
server 127.0.0.1:30008;
}
Nginx、workhorse和unicorn之间的关系
gitlab-ctl reconfigure 重新更新配置
gitlab-ctl restart 重启服务
gitlab-ctl tail 查看日志
备份命令：gitlab-rake gitlab:backup:create
会在/var/opt/gitlab/backups下生成一个带时间的tar文件
每天晚上定时备份，运行crontab -e，添加
0 1 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1
注意：环境变量CRON=1的作用是如果没有任何错误发生时， 抑制备份脚本的所有进度输出
只保存最近7天的备份，编辑 /etc/gitlab/gitlab.rb 配置文件,找到gitlab_rails[‘backup_keep_time’]，设置为你想要设置的值。
gitlab_rails['backup_keep_time'] = 604800
Gitlab的恢复操作会先将当前所有的数据清空，然后再根据备份数据进行恢复。
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
gitlab-ctl status
查看一下unicorn和sidekiq是否已经down了，然后运行：
chmod 777 备份文件
gitlab-rake gitlab:backup:restore BACKUP=备份文件编号
比如：
gitlab-rake gitlab:backup:restore BACKUP=1539841224_2018_10_18_11.3.5.3
再次启动gitlab
gitlab-ctl restart
