重新部署成功了。过程大概如下：
删除observer目录。删除/home/admin/.obd/目录下所有的东西。
执行：obd cluster deploy obce-single -c obce-single.yaml
[admin@duizhang ~]$ obd cluster start obce-single
Get local repositories and plugins ok
Open ssh connection ok
Cluster param config check ok
Check before start observer ok
[WARN] (192.168.211.54) clog and data use the same disk (/)
Start observer ok
observer program health check ok
Connect to observer ok
Initialize cluster
Cluster bootstrap ok
Wait for observer init ok

当deploy后修改配置文件正确的方法是 ：obd cluster edit-config obce-single
修改才会生效。
可能是这个原因。
后面你删除了 ~/.obd 目录， 重新部署，那效果一样。
