gitlab-runner一直处于挂起/pedding状态

Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 

如上所示，由于在配置runner时，选择了deploy的tags，而在gitlab后台默认是不允许没有任何标签的作业，我上传任务时没有打tags，所以被阻塞，勾选这个即可。

在Docker部署GitLab后，使用持续集成提交到GitLab开始几次正常通过测试，后来发现每次都是任务排队，重启Docker也不行，后来想到gitlab是和gitlab-runner是分在两个容器中的（为了GitLab压力考虑，gitlab-runner耗性能），在runner容器里执行

gitlab-ci-multi-runner restart

进行重启runner操作，刷新GitLab页面，就会发现自动执行runner任务了

终于找到原因了，是runner服务down掉了
