Zookeeper错误：无法打开选举地址上的X通道

我已经在3个不同的AWS服务器中安装了zookeeper。以下是所有服务器中的配置

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
server.1=x.x.x.x:2888:3888
server.2=x.x.x.x:2888:3888
server.3=x.x.x.x:2888:3888

所有这三个实例都有一个myid文件，var/zookeeper其中包含适当的ID。所有这三台服务器都通过aws控制台打开了所有端口。但是，当我运行zookeeper服务器时，在所有实例中都出现以下错误。

回答：

如何在每个节点中定义本地服务器的IP？如果您提供了公共IP，则侦听器将无法连接到端口。您必须为当前节点指定0.0.0.0

server.1=0.0.0.0:2888:3888
server.2=192.168.10.10:2888:3888
server.3=192.168.2.1:2888:3888

此更改也必须在其他节点上执行。
