一、下载
官网：http://zookeeper.apache.org/releases.html
镜像：https://www.apache.org/dyn/closer.cgi/zookeeper
二、安装
ZooKeeper是运行在Java环境下的，所以需要先安装JDK，网上教程一大堆，不再赘述，也可以参考我的另外一篇文章：CentOS安装JDK
解压
shell> tar -xvf zookeeper-3.5.3-beta.tar.gz -C /usr/local/
修改配置
shell> cd /usr/local/zookeeper-3.5.3-beta/conf
shell> cp zoo_sample.cfg zoo.cfg
shell> vim zoo.cfg
dataDir=/usr/local/zookeeper-3.5.3-beta/data
dataLogDir=/usr/local/zookeeper-3.5.3-beta/logs
三、启动&停止
1、启动
shell> bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
2、查看状态
shell> bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone
3、停止
shell> bin/zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
4、重启
shell> bin/zkServer.sh restart
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
四、测试
1、jps，查看QuorumPeerMain是否存在
shell> jps
19748 Jps
19159 QuorumPeerMain
2、zkServer.sh status
shell> bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone
3、zkClient
shell> bin/zkCli.sh -server localhost:2181
Connecting to localhost:2181
