zookeeper单节点安装Standalones模式，

本文使用的是：zookeeper-3.4.6.tar.gz

[root@master cloud]# java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

[root@master cloud]# tar -zxvf zookeeper-3.4.6.tar.gz

[root@master cloud]# cd zookeeper-3.4.6/conf

[root@master conf]# cp zoo_sample.cfg zoo.cfg

[root@master conf]# vim zoo.cfg

修改其中的

dataDir=/root/cloud/zookeeper-3.4.6/data

别的不用改动

[root@master zookeeper-3.4.6]# cd bin/
[root@master bin]# ./zkServer.sh start
JMX enabled by default
Using config: /root/cloud/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[root@master bin]# jps
2303 Jps
2285 QuorumPeerMain

[root@master bin]# ./zkServer.sh status
JMX enabled by default
Using config: /root/cloud/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: standalone

单节点的时，Mode会显示为standalone
