本文详细介绍了如何搭建Zookeeper集群，包括下载安装、配置文件修改、节点ID分配、启动节点及常用命令使用。

一.搭建Zookeeper集群

1.下载地址

http://zookeeper.apache.org/releases.html#download

2.解压缩，tar -xvzf zookeeper-3.4.6.tar.gz

复制出3个节点

[root@HTML5 zookeeper]# cp -r /usr/zht/zookeeper-3.4.6 zookeeper-1

[root@HTML5 zookeeper]# cp -r /usr/zht/zookeeper-3.4.6 zookeeper-2

[root@HTML5 zookeeper]# cp -r /usr/zht/zookeeper-3.4.6 zookeeper-3

（本文是在一台机器测试，实际上肯定是要分在几台服务器上部署的，否则没有意义）

3.分别修改配置文件

[root@HTML5 zookeeper]# cd zookeeper-1/ conf/

[root@HTML5 conf]# cp zoo_sample.cfg zoo.cfg

修改zoo.cfg如下：

# 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.

dataDir=/usr/local/data/zookeeper/zookeeper-1

dataLogDir=/usr/local/data/zookeeper/logs-1

# the port at which the clients will connect

clientPort=1181

server.1=127.0.0.1:2888:3888

server.2=127.0.0.1:4888:5888

server.3=127.0.0.1:6888:7888

标红部分为需要修改内容， clientPort在多服务器时不必修改

4.给节点分配ID

进入上文配置的 dataDir=/usr/local/data/zookeeper/zookeeper-1，新建文件：myid，内容为该节点ID
如：/usr/local/data/zookeeper/zookeeper-1 目录下myid内容为1

5.启动各节点

[root@HTML5 bin]# ./zkServer.sh start

JMX enabled by default

Using config: /usr/local/zookeeper/zookeeper-1/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

[root@HTML5 bin]# ./zkServer.sh status

JMX enabled by default

Using config: /usr/local/zookeeper/zookeeper-1/bin/../conf/zoo.cfg

Mode: follower
