环境

使用阿里云Centos7.6

操作

 zkServer.sh status
Using config: /root/zookeeper/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
`Error contacting service. It is probably not running.`

分析

cat /root/zookeeper/data/logs/zookeeper-root-server-iZwz90bzsu76894wmz3hieZ.out

解决方案

阿里云专有网络不能使用外网IP，只能使用内网ip。如果是经典网络就可以使用外网IP。
