服务器无法相互通信。救命 ！
最佳答案
如果您netstat -tulnap服务器，端口2888、3888 ad 2181是否已打开并正在侦听，或者每个框中的localhost（0.0.0.0）只能打2181、288和3888？
编辑：
查看您的netstat，我看到以下内容：
tcp 0 0 192.168.0.125:2888 0.0.0.0:*听
tcp 0 0 192.168.0.125:3888
表示您需要修改etc / hots以将0.0.0.0与主机名一起使用。
因此，如果该盒子的主机名是zoobox1，则/ etc / hosts需要在其中包含以下行：
127.0.0.1 localhost
0.0.0.0 zoobox1
这样，netstat -tulnap将打开端口2888和3888，以便本地主机可以连接其他服务器。
