1. 下载地址
http://www.apache.org/dyn/closer.cgi/zookeeper/
2. 解压
tar zxvf zookeeper-3.4.8.tar.gz
3. 重命名
在对应的zookeeper-3.4.8/conf 下有一个文件zoo_sample.cfg的这个文件里面配置了监听客户端连接的端口等一些信息，Zookeeper 在启动时会找zoo.cfg这个文件作为默认配置文件，所以我们重命名zoo_sample.cfg为zoo.cfg。使用如下命令：
mv zoo_sample.cfg zoo.cfg
4. 配置文件 zoo.cfg
# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial# synchronization phase can takeinitLimit=10# The number of ticks that can pass between# sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just# example sakes.dataDir=/home/xiaosi/zookeeper/data# the port at which the clients will connectclientPort=2181# the maximum number of client connections.# increase this if you need to handle more clients#maxClientCnxns=60## Be sure to read the maintenance section of the# administrator guide before turning on autopurge.## http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
只需修改dataDir项即可，不要使用默认的/tmp目录；
如果需要集群，zoo.cfg的内容如下：(其中data目录和server地址需改成你真实部署机器的信息)：
tickTime=2000initLimit=10syncLimit=5dataDir=/home/xiaosi/zookeeper/dataclientPort=2181server.1=10.20.153.10:2555:3555server.2=10.20.153.11:2555:3555
并在data目录下放置myid文件：(上面zoo.cfg中的dataDir)
sudo mkdir datasudo vim myid
myid指明自己的id，对应上面zoo.cfg中server.后的数字，第一台的内容为1，第二台的内容为2，myid内容如下：
1
5. 启动
进入bin目录 ./zkServer.sh start
xiaosi@Qunar:/opt/zookeeper-3.4.8/bin$ ./zkServer.sh startZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfgStarting zookeeper ... STARTED
查看zookeeper状态：
xiaosi@Qunar:/opt/zookeeper-3.4.8/bin$ ./zkServer.sh statusZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfgMode: standalone
当zookeeper启动时，会在/home/xiaosi/zookeeper/data下生成一个zookeeper_server.pid文件。记录了zookeeper进程的进程ID号（本例中为13402）。
xiaosi 13402 6831 0 00:06 pts/20 00:00:00 /opt/jdk1.7.0_40/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /opt/zookeeper-3.4.8/bin/../build/classes:/opt/zookeeper-3.4.8/bin/../build/lib/*.jar:/opt/zookeeper-3.4.8/bin/../lib/slf4j-log4j12-1.6.1.jar:/opt/zookeeper-3.4.8/bin/../lib/slf4j-api-1.6.1.jar:/opt/zookeeper-3.4.8/bin/../lib/netty-3.7.0.Final.jar:/opt/zookeeper-3.4.8/bin/../lib/log4j-1.2.16.jar:/opt/zookeeper-3.4.8/bin/../lib/jline-0.9.94.jar:/opt/zookeeper-3.4.8/bin/../zookeeper-3.4.8.jar:/opt/zookeeper-3.4.8/bin/../src/java/lib/*.jar:/opt/zookeeper-3.4.8/bin/../conf:.:/opt/jdk1.7.0_40/lib -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /opt/zookeeper-3.4.8/bin/../conf/zoo.cfgxiaosi 13497 12559 0 00:07 pts/20 00:00:00 grep --color=auto zookeeper
6. 关闭
进入bin目录 ./zkServer.sh stop
xiaosi@Qunar:/opt/zookeeper-3.4.8/bin$ ./zkServer.sh stopZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfgStopping zookeeper ... STOPPED
