进入http://zookeeper.apache.org/releases.html下载zookeeper的最新稳定版本，
当前稳定版本为zookeeper-3.4.6.tar.gz
解压到/usr/local/zookeeper
进入
[root@localhost conf]# pwd /usr/local/zookeeper/zookeeper-3.4.6/conf
修改zoo_sample.cfg为zoo.cfg
zoo.cfg文件内容为
[root@localhost 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=/usr/local/zookeeper/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
