如何检查和定位问题？
使用命令检查所有服务的状态
sudo gitlab-ctl status
检查服务状态如下
run: gitlab-workhorse: (pid 4752) 10862s; run: log: (pid 1077) 13288s
run: logrotate: (pid 16553) 59s; run: log: (pid 1079) 13288s
run: nginx: (pid 4764) 10861s; run: log: (pid 1076) 13288s
run: postgresql: (pid 4770) 10860s; run: log: (pid 1073) 13288s
run: redis: (pid 4778) 10860s; run: log: (pid 1072) 13288s
run: sidekiq: (pid 4782) 10859s; run: log: (pid 1075) 13288s
run: unicorn: (pid 4786) 10859s; run: log: (pid 1074) 13288s
定位问题
从服务状态信息中显示数据库postgresql的状态是down，即服务停止。
检查数据库postgresql的运行日志，检查出现什么错误？
$ sudo gitlab-ctl tail postgresql

日志显示，数据库的访问权限应该是只有用户本身有读写执行的权限，用户组和其他用户不能有权限。
修改数据库数据的权限后，检查服务运行正常。
了解了问题的定位和解决方式，其他问题也很容易在日志中发现和解决，问题可能是磁盘空间少，用户权限错误或者其他原因。
gitlab管理员密码忘记，怎么重置密码
Gitlab 修改root用户密码
使用rails工具打开终端
sudo gitlab-rails console production
查询用户的email，用户名，密码等信息，id:1 表示root账号
user = User.where(id: 1).first
重新设置密码
user.password = ‘新密码‘
user.password_confirmation = ‘新密码‘
保存密码
user.save!
完整的操作ruby脚本
user = User.where(id: 1).first
user.password = ‘新密码‘
user.password_confirmation = ‘新密码‘
user.save!
然后使用重置过的密码重新登录。
