How to reset your root password
　　Log into your server with root privileges. Then start a Ruby on Rails console.
　　Start the console with this command:

gitlab-rails console production　　

　　Wait until the console has loaded.
　　There are multiple ways to find your user. You can search for email or username.

user = User.where(id: 1).first　　

　　or

user = User.find_by(email: 'admin@local.host')　　

　　Now you can change your password:

user.password = 'secret_pass'　　
user.password_confirmation = 'secret_pass'
　　

　　It's important that you change both password and password_confirmation to make it work.
　　Don't forget to save the changes.

user.save!　　

　　Exit the console and try to login with your new password.
