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 机器上设置 zookeeper 集群，但不断收到相同的错误:

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

1) 我对所有三台机器都有相同的安全组.
2)在conf中使用机器的私有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

# Purge task interval in hours

#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) 甚至使用自己机器的实际私有 ip 而不是0.0.0.0"进行测试.

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

无法确定出了什么问题.

Not been able to identify what's going wrong.

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
