1.2. gitlab-ctl tail gitlab-rails

2、解决问题：

gitlab-rails dbconsole，输入如下内容：
UPDATE projects SET runners_token = null, runners_token_encrypted = null;
UPDATE namespaces SET runners_token = null, runners_token_encrypted = null;
UPDATE application_settings SET runners_registration_token_encrypted = null;
UPDATE ci_runners SET token = null, token_encrypted = null;

gitlab-rails console，输入如下内容：
ApplicationSetting.current.reset_runners_registration_token!
