参考官方文档 How to reset your root password How to unlock a locked user from the command line 操作背景 Gitlab是Docker部署，Jenkins账号登陆不了，开始是怀疑密码不对，通过控制台登陆重置了密码，还是登陆不了，怀疑是Jenkins用户被锁住了（默认错误登陆超过10次会锁定），解锁后登陆成功。

操作步骤 1.登陆Gitlab所在容器

[root@188-20 ~]# docker exec -it gitlab /bin/bash
root@gitlab:/# ls
RELEASE  bin   dev  home  lib64  mnt  proc  run   srv  tmp  var
assets   boot  etc  lib   media  opt  root  sbin  sys  usr

2.登陆控制台

root@gitlab:/# gitlab-rails console production
Loading production environment (Rails 4.2.10)

3.通过邮箱找到用户

irb(main):003:0> user=User.where(email:'jenkins@domian.com').first
=> #<User id:12 @jenkins>

4.修改密码并保存
