v3.0.3到3.1.0省级失败

[allegrox]

使用ansible-playbook rolling_update.yml省级时，提示：
[192.168.5.50]: Ansible FAILED! => playbook: rolling_update.yml; TASK: Check pd cluster status; message: {"changed": false, "content": "", "msg": "Status code was -1 and not [200]: Request failed: <urlopen error [Errno 111] Connection refused>", "redirected": false, "status": -1, "url": "http://192.168.5.50:2379/pd/health"}

滚动升级需要集群正常运行时才能使用，从报错看集群没有运行或者处于异常状态
