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 tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# 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=/home/xiaosi/zookeeper/data
# the port at which the clients will connect
clientPort=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=2000
initLimit=10
syncLimit=5
dataDir=/home/xiaosi/zookeeper/data
clientPort=2181
server.1=10.20.153.10:2555:3555
server.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 data
sudo 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 start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
查看zookeeper状态:
xiaosi@Qunar:/opt/zookeeper-3.4.8/bin$ ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: 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 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 stop
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
