解压zookeeper包:[root@node01 ~]# tar xf zookeeper-3.4.8.tar.gz -C /usr/local cd /usr/local/[root@node01 local]# ln -sv zookeeper-3.4.8 zookeeper

创建数据目录：mkdir /data/zookeeper -pv [root@node01 conf]# mv /usr/local/zookeeper/conf zoo_sample.cfg zoo.cfg

[root@node01 conf]# cat zoo.cfg |egrep -v "^$|^#"tickTime=2000initLimit=10syncLimit=5dataDir=/data/zookeeperclientPort=2181server.1=192.168.100.10:2888:3888server.2=192.168.100.20:2888:3888server.3=192.168.100.30:2888:3888
