1、下载zookeeper

本系统使用的是 zookeeper-3.4.6

2、解压

tar -xf zookeeper-3.4.6.tar.gz

3、将zookeeper-3.4.6/conf目录下的zoo_sample.cfg文件拷贝一份，命名为为“zoo.cfg”

4、修改zoo.cfg配置文件

修改zoo.cfg内容为：

# 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=/home/storm/zookeeper-3.4.3/zookeeperdir/zookeeper-data  dataLogDir=/home/storm/zookeeper-3.4.3/zookeeperdir/logs     # the port at which the clients will connect  clientPort=2181  #  # 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     # 2888,3888 are election port  server.1=zookeeper:2888:3888
