Mac下ZooKeeper环境部署，Linux方法相同

1、首先到官网下载Zookeeper，目前的稳定版本为3.4.9，下载地址。Liniux下可以直接进入/usr目录，使用wget命令直接下载。

cd /usrsudo wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

2、解压下载ZooKeeper-3.4.9.tar.gz包，重命名目录ZooKeeper-3.4.9为ZooKeeper，删除下载的ZooKeeper-3.4.9包；

sudo tar -xf ZooKeeper-3.4.9.tar.gzsudo mv ZooKeeper-3.4.9 ZooKeepersudo rm -f ZooKeeper-3.4.9.tar.gz

3、修改环境变量，在profile文件的最后部分导出ZooKeeper的安装路径，这里我把ZooKeeper放在了/Library/文件夹下，大家可以随意放置。

sudo vim /etc/profile# ZooKeeper配置export ZOOKEEPER_INSTALL=/Library/ZooKeeperexport PATH=$PATH:$ZOOKEEPER_INSTALL/bin

4、创建ZooKeeper配置文件

cd ZooKeeper/confcp zoo_sample.cfg zoo.cfg

5、执行vim zoo.cfg，修改配置文件内容

# 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=/tmp/zookeeper/datadataLogDir=/tmp/zookeeper/log# 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

6、创建配置中相应的目录

cd /tmpmkdir ZooKeepercd ZooKeepermkdir logmkdir data

7、启动ZooKeeper

cd /Library/Zookeeper/bin./zkServer.sh

8、可以使用ZooKeeper自带的客户端工具zkCli.sh来查看ZooKeeper的节点简历情况，至此ZooKeeper环境部署完成。
