我用VMWare搭建了3个主机的zookeeper，已经实现了数据同步了（在一个主机创建了数据，在其他主机，启动客户端，都能查看了）。但，其中一个kill -9 id后，其他的都不能用了。
[root@wqb99 ~]# /itcast/zookeeper-3.4.9/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /itcast/zookeeper-3.4.9/bin/../conf/zoo.cfg
Mode: leader
[root@wqb99 ~]# jps
2739 Jps
2531 QuorumPeerMain
[root@wqb99 ~]# kill -9 2531
[root@wqb99 ~]# jps
2749 Jps
[root@wqb99 ~]#
发现其他节点也宕机了
（1）
[root@wqb88 ~]# /itcast/zookeeper-3.4.9/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /itcast/zookeeper-3.4.9/bin/../conf/zoo.cfg
Mode: follower
[root@wqb88 ~]# /itcast/zookeeper-3.4.9/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /itcast/zookeeper-3.4.9/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
[root@wqb88 ~]#
（2）
[root@wqb66 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /itcast/zookeeper-3.4.9/bin/../conf/zoo.cfg
Mode: follower
[root@wqb66 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /itcast/zookeeper-3.4.9/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
[root@wqb66 bin]#

感谢您的帮忙，我认真阅读了您推荐的这两篇博文，我没有找到有效的解决方案。请大神再帮忙分析分析
集群中每个机器都需要感知其他机器的存在
比如：
集群机器配置:
server1=ip1:2888:3888;
server2=ip2:2888:3888;
server3=ip3:2888:3888;
2888是follow连接leader的端口号，3888是选举leader的端口号
问题的资料补充——zoo.cfg配置文件：
[root@wqb66 conf]# cat zoo.cfg
# 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=/itcast/zookeeper-3.4.9/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.purgeInterval=1
