第一次 web 界面打开后 需要修改密码 默认用户为：root

覆盖原文件gitlab-rails汉化：
#备份原文件
cp -rp /opt/gitlab/embedded/service/gitlab-rails{,.bak_$(date +%F)}
#将汉化包覆盖过去(\也需要敲) 记得cd 的汉化包文件夹里：

\cp -rf ./* /opt/gitlab/embedded/service/gitlab-rails

gitlab-ctl reconfigure
gitlab-ctl start

附. 常用gitlab命令
gitlab-ctl reconfigure　　// 重新应用gitlab的配置
gitlab-ctl restart　　　　// 重启gitlab服务
gitlab-ctl status　　　 // 查看gitlab运行状态
gitlab-ctl stop　　　　 // 停止gitlab服务
gitlab-ctl tail　　　　　// 查看gitlab运行日志

优化：
1、减少进程数
修改配置文件gitlab.rb中的worker_processes:

unicorn[‘worker_processes’] = 2
复制代码
默认是被注释掉的，官方建议该值是CPU核心数加一，可以提高服务器的响应速度，如果内存只有4G，或者服务器上有其它业务，就不要改了，以免内存不足。另外，这个参数最小值是2，设为1，服务器可能会卡死。

2、减少数据库缓存
默认为256MB，可适当改小

postgresql[‘shared_buffers’] = “256MB”
复制代码
3、减少数据库并发数
默认为8，可适当改小

postgresql[‘max_worker_processes’] = 8
复制代码
4、减少sidekiq并发数
默认是25，可适当改小

sidekiq[‘concurrency’] = 25
复制代码
重启服务
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
