在CentOS7上安装zookeeper-3.4.9服务。

1、下载zookeeper-3.4.9：

wget http://apache.fayea.com/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

2、解压缩zookeeper-3.4.9.tar.gz:

tar -zxvf zookeeper-3.4.9.tar.gz

3、移动zookeeper-3.4.9到/usr/local目录下

mv zookeeper-3.4.9 /usr/local/zookeeper-3.4.9

4、进入到conf目录

cd /usr/local/zookeeper-3.4.9/conf

5、复制zoo_sample.cfg文件并且命名为zoo.cfg

cp zoo_sample.cfg zoo.cfg

6、修改参数：

vi zoo.cfg

# The number of milliseconds of each tick#这个时间是作为Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳tickTime=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.#zookeeper保存数据的目录，默认情况下zookeeper将写数据的日志文件也保存在这个目录里dataDir=/usr/local/zookeeper-3.4.9/tmp/zookeeper# the port at which the clients will connect#客户端连接zookeeper服务器的端口，zookeeper会监听这个端口，接受客户端的访问请求clientPort=2181# the maximum number of client connections.# increase this if you need to handle more clients#限制连接到zooKeeper的客户端的数量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## The number of snapshots to retain in dataDir#autopurge.snapRetainCount=3# Purge task interval in hours# Set to "0" to disable auto purge feature#autopurge.purgeInterval=1
