问题说明

一段时间没有访问gitlab，gitlab的管理员和密码都忘记了。

解决方案

进入rails控制台

gitlab-rails console 

root@1a0cebf0b519:/# gitlab-rails console 
--------------------------------------------------------------------------------
 Ruby:         ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux]
 GitLab:       13.10.0 (5eafdaf7b07) FOSS
 GitLab Shell: 13.17.0
 PostgreSQL:   12.5

Loading production environment (Rails 6.0.3.4)
irb(main):001:0> 

查询用户

 user = User.where(id:1).first

irb(main):001:0> user = User.where(id:1).first
=> #<User id:1 @root>

可以找到一个root用户。

重置密码

 user.password=密码

irb(main):004:0> user.password='dowhere.com'
=> "dowhere.com"
irb(main):005:0> user.save!

=> true

保存更改

user.save!

irb(main):005:0> user.save!
