刷新
source /etc/profile
进入到zookper目录下的conf文件夹
cd /etc/hadoop/zookeeper/conf

mv zoo_sample.cfg zoo.cfg
对zoo.cfg配置文件
vim zoo.cfg
//# The number of milliseconds of each ticktickTime=2000
maxClientCnxns=0
//# The number of ticks that the initial

itLimit=50
//# 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=/etc/hadoop/hadoop/zookeeperdata
//# the port at which the clients will connectclientPort=2181
server.1=192.168.3.120:2888:3888
server.2=192.168.3.130:2888:3888
server.3=192.168.3.140:2888:3888
在hadoop文件夹下面新建zookperdata文件夹
cd /etc/hadoop/hadoop
mkdir zookeeperdata
创建myid
cd zookeeperdata
mkdir myid
将主节点的zookeeper复制到子节点中
scp -r /etc/hadoop/zookeeper hadoop02:/etc/hadoop/
scp -r /etc/hadoop/zookeeper hadoop03:/etc/hadoop/
