dataDir=/usr/local/zookeeper-3.4.6/data

dataLogDir=/usr/local/zookeeper-3.4.6/log

# the port at which the clients will connect

clientPort=2181

# the maximum number of client connections.

#

#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

#autopurge.purgeInterval=1

server.1=master:2888:3888

server.2=slave1:2888:3888

server.3=slave2:2888:3888

1. 创建 log/，并添加data/myid

master data/myid    1

slave1  data/myid    2

slave1  data/myid    3
