问题描述
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
I have installed zookeeper in 3 different aws servers. The following is the configuration in all the servers
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
所有三个实例在var/zookeeper处都有一个myid文件，并在其中包含适当的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，在所有实例中都会出现以下错误.
All the three instance have a myid file at var/zookeeper with appropriate id in it. All the three servers have all ports open from the aws console. But when I run the zookeeper server, I get the following error in all the instances.

推荐答案
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
How have defined the ip of the local server in each node? If you have given the public ip, then the listener would have failed to connect to the port. You must specify 0.0.0.0 for the current node
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.
This change must be performed at the other nodes too.
