问题

浏览器打开，页面显示如下错误信息：
500: We’re sorry, something went wrong on our end Request ID: 01JCA8W7D78HER827RNV9S25EY Try refreshing the page, or going back and attempting the action again. Please contact your GitLab administrator if this problem persists.

查看日志

cat /var/log/gitlab/gitlab-rails/production.log

解决方案

按照如下方式重置token

进入gitlab-psql命令行，使用
UPDATE projects SET runners_token = null, runners_token_encrypted = null;
语句重置token

[root@gitlab ~]# gitlab-psql -d gitlabhq_production
gitlabhq_production=# UPDATE projects SET runners_token = null, runners_token_encrypted  = null;

重新刷新浏览器，发现可以正常操作，不用重启gitlab服务器
