KubeSphere2.1.1在线安装multi-node报错

昨天在我们群主的帮助下，成功安装完成了All-in-one单节点，今天将单节点删除后，再安装Multi-node，还是报之前遇到过的两类问题：

1. 节点找不到，错误信息如下：
   2020-05-15 18:59:33,204 p=23124 u=root | fatal: [k8sphere02]: FAILED! => {

   }
   STDERR:

}
STDERR:

2. ks-installer安装报错
   fatal: [k8sphere01]: FAILED! => {
   “attempts”: 30,
   “changed”: true,
   “cmd”: “/usr/local/bin/kubectl get pod -n kubesphere-system | grep Running | grep ks-installer”,
   “delta”: “0:00:00.072270”,
   “end”: “2020-05-15 19:15:20.891646″,
   “rc”: 1,
   “start”: “2020-05-15 19:15:20.819376”
   }
   MSG:

执行以下命令，结果如下：

rayzhou2017 我也明白都是因为两个node找不到，可我检查了很多篇，也没有发现是啥原因导致其找不到啊！看看大家遇到这种问题，是怎么解决的？

rayzhou2017 在我的部署中出现过好几次这种问题：

1. 第一次是两个node（k8sphere02,k8sphere03），其中一个k8sphere02找不到；
2. 第二次是我换一个新node（k8sphere03,glusterfs-client）,能正常；
3. 后来都卸载后，再次安装1master+2node（k8sphere02,k8sphere03），发现两个node都找不到了。
