ZooKeeper伪分布式集群安装及使用

前言
ZooKeeper是Hadoop家族的一款高性能的分布式协作的产品。在单机中，系统协作大都是进程级的操作。分布式系统中，服务协作都是跨服务器才能完成的。在ZooKeeper之前，我们对于协作服务大都使用消息中间件，随着分布式系统的普及，用消息中间件完成协作，会有大量的程序开发。ZooKeeper直接面向于分布式系统，可以减少我们自己的开发，帮助我们更好完成分布式系统的数据管理问题。

1. zookeeper介绍
ZooKeeper是一个为分布式应用所设计的分布的、开源的协调服务，它主要是用来解决分布式应用中经常遇到的一些数据管理问题，简化分布式应用协调及其管理的难度，提供高性能的分布式服务。ZooKeeper本身可以以Standalone模式安装运行，不过它的长处在于通过分布式ZooKeeper集群（一个Leader，多个Follower），基于一定的策略来保证ZooKeeper集群的稳定性和可用性，从而实现分布式应用的可靠性。
ZooKeeper是作为分布式协调服务，是不需要依赖于Hadoop的环境，也可以为其他的分布式环境提供服务。
2. zookeeper单节点安装Standalones模式
系统环境：
- Linux Ubuntu 12.04.2 LTS 64bit server

启动zookeeper

停止ZooKeeper服务

所谓 “伪分布式集群” 就是在，在一台PC中，启动多个ZooKeeper的实例。“完全分布式集群” 是每台PC，启动一个ZooKeeper实例。
由于我的测试环境PC数量有限，所以在一台PC中，启动3个ZooKeeper的实例。
创建环境目录
~ mkdir /home/conan/zoo/zk1~ mkdir /home/conan/zoo/zk2~ mkdir /home/conan/zoo/zk3#新建myid文件~ echo "1" > /home/conan/zoo/zk1/myid~ echo "2" > /home/conan/zoo/zk2/myid~ echo "3" > /home/conan/zoo/zk3/myid分别修改配置文件
修改：dataDir,clientPort
增加：集群的实例，server.X，”X”表示每个目录中的myid的值
~ vi /home/conan/toolkit/zookeeper345/conf/zk1.cfgtickTime=2000initLimit=10syncLimit=5dataDir=/home/conan/zoo/zk1clientPort=2181server.1=192.168.1.201:2888:3888server.2=192.168.1.201:2889:3889server.3=192.168.1.201:2890:3890~ vi /home/conan/toolkit/zookeeper345/conf/zk2.cfgtickTime=2000initLimit=10syncLimit=5dataDir=/home/conan/zoo/zk2clientPort=2182server.1=192.168.1.201:2888:3888server.2=192.168.1.201:2889:3889server.3=192.168.1.201:2890:3890~ vi /home/conan/toolkit/zookeeper345/conf/zk3.cfgtickTime=2000initLimit=10syncLimit=5dataDir=/home/conan/zoo/zk3clientPort=2183server.1=192.168.1.201:2888:3888server.2=192.168.1.201:2889:3889server.3=192.168.1.201:2890:38903个节点的ZooKeeper集群配置完成，接下来我们的启动服务。
