Amazon ec2 ec2上的zookeeper无法运行

各位,， 我最近在ec2上设置了zookeeper 我遵循了ec2的手册，但它仍然显示错误：

root@ip-172-31-15-65:/home/yjiang/zookeeper-3.4.5/bin# ./zkServer.sh status
JMX enabled by default
Using config: /home/yjiang/zookeeper-3.4.5/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

但该实例正在后台运行。 然后，当我使用./zkCli.sh–server-server-ip:2181命令时，它显示如下

root@ip-172-31-15-68:/home/yjiang/zookeeper-3.4.5/bin# ./zkCli.sh -server ec2-54-213-208-202.us-west-2.compute.amazonaws.com:2181

仅供参考，我已将端口2181、2888和3888添加到所有计算机的防火墙中。我甚至在所有机器上都禁用了防火墙，它仍然不工作。但在我的本地应用程序中，使用相同的配置方法从来没有任何问题。 请帮帮我

非常感谢。

问题可能与AWS间隔与外部地址有关。每个EC2实例都有一个从AWS内部使用的地址（专用地址）和一个在AWS外部使用的地址。您的配置文件显示server2使用ec2-54-213-208-202.us-west-2.compute.amazonaws.com，这绝对是一个外部地址。如果您的所有服务器和AWS中的所有服务器都使用专用地址。

AWS公用主机名从同一区域内解析为其专用IP。这始终是首选的方式，因为显式使用公共IP的速度较慢，流量将被计费。您找到解决方法了吗？
