Gitlab忘记root密码

如果忘记了 root 密码，或者接手了一个不知道密码的 Gitlab，可以通过重置密码进行恢复。

登录到 Gitlab 服务器，执行如下命令：

gitlab-rails console production

如果此时有报错：

[root@localhost ~]# gitlab-rails console production

则可能是 Gitlab 版本不一样，然后参数方式不一样，需要用如下方式：

[root@localhost ~]# gitlab-rails console -e production

接着查询一下用户：

irb(main):001:0> user = User.where(username:"root").first
=> #

然后修改密码：

irb(main):002:0> user.password = "xuhuan911226"
=> "xuhuan911226"

然后保存：

irb(main):003:0> user.save!
=> true
