Question

我正在尝试在3台AWS ec2计算机上设置zookeeper群集，但不断收到相同的错误：

2016-10-19 16:30:23,177 [myid:2] - WARN  [QuorumPeer[myid=2]/0:0:0:0:0:0:0:0:2181:QuorumCnxManager@382] - Cannot open channel to 3 at election address /xxx.31.34.102:3888

1）我对所有三台机器都有相同的安全组 2）在conf中使用私人机器ips

# 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）甚至使用自己机器的实际私有IP而不是＆＃34; 0.0.0.0＆＃34;进行测试。

无法确定出现了什么问题。

Answer 1

对于每个节点，您必须确保已将0.0.0.0指定为节点的IP地址。

：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
