AWS上的Zookeeper集群 [英] Zookeeper cluster on AWS

问题描述

我正在尝试在3台AWS ec2计算机上设置Zookeeper集群，但不断出现相同错误：

I am trying to setup a zookeeper cluster on 3 AWS ec2 machines, but continuously getting same error:

1）我具有相同的安全组所有这三台机器。

2）在conf中使用机器的专用ips

1) I have same security group for all three machines.
2) Using private ips of machine in conf

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/opt/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeIinterval=1
server.1=0.0.0.0:2888:3888
server.2=x.31.34.105:2888:3888
server.3=x.31.34.102:2888:3888

3）甚至使用自己计算机的实际私有ip（而不是 0.0.0.0）进行了测试。

3) Even tested with actual private ip of own machine instead of "0.0.0.0".

无法识别出问题所在。

推荐答案

对于每个节点，您必须确保已指定0.0 .0.0作为节点的ip地址。

For each node you must make sure that you have specified 0.0.0.0 as the node's ip address.

即：对于服务器01

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

对于服务器02

server.1=192.168.x.x:2888:3888
server.2=0.0.0.0:2888:3888
server.3=192.168.2.1:2888:3888

对于服务器

server.1=192.168.x.x:2888:3888
server.2=192.168.10.10:2888:3888
server.3=0.0.0.0:2888:3888
