Linux下zookeeper集群搭建（至少需要三台主机（虚拟机））

1，官网下载zookeeper http://zookeeper.apache.org/releases.html

2，配置好系统的Java环境，将压缩包zookeeper-3.4.12.tar.gz解压至Linux任意目录下，

3，更改conf目录下的文件zoo_sample.cfg 重命名为zoo.cfg或则重新创建一个新的zoo.cfg文件，文件配置如下

# 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.（保存数据的路径，需要绝对路径）
dataDir=/home/zookeeper-3.4.12/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
