编辑 zoo.cfg 文件,

修改 dataDir 属性等于 /tmp/zookeeper 如下第13行所示

 # 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.
 # 主要是这里<需要修改成zookeeper的数据文件目录>
 dataDir=/home/zookeeper/zookeeperData
 # 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
