进入官网下载 Zookeeper，这里我们使用的版本为 Zookeeper-3.5.7
Zookeeper 官网地址： http://zookeeper.apache.org/
zookeeper 安装模式有三种：单机模式：单机单 server；集群模式：多机多 server，形成集群；伪集群模式：单机多 server，形成伪集群。
二、Zookeeper 单机模式部署
1、安装 JDK
安装JDK
可以参照：Java基础：Java程序设计环境
2、安装 Zookeeper
官网下载
拷贝 apache-zookeeper-3.5.7-bin.tar.gz 到 Linux系统下
解压到指定目录：
tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C /opt/module/改名
mv apache-zookeeper-3.5.7-bin zookeeper-3.5.73、修改 Zookpeeper 配置
进入conf目录
mv zoo_sample.cfg zoo.cfg
mkdir /opt/module/zookeeper-3.5.7/zkData
vi 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=/opt/module/zookeeper-3.5.7/zkData
# 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
#
# 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=14、运行 Zookeeper
启动Zookeeper：bin/zkServer.sh start
查看进程：jps
客户端访问：bin/zkCli.sh
三、Zookeeper 集群安装
1、安装JDK（每一台服务器）；
安装JDK
可以参照：Java基础：Java程序设计环境
2、安装 Zookeeper
拷贝 apache-zookeeper-3.5.7-bin.tar.gz 到 Linux系统下（每一台服务器）
解压到指定目录（每一台服务器）：
tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C /opt/module/改名（每一台服务器）
mv apache-zookeeper-3.5.7-bin zookeeper-3.5.73、修改 Zookpeeper 配置
进入conf目录（每一台服务器）
mv zoo_sample.cfg zoo.cfg（每一台服务器）
mkdir /opt/module/zookeeper-3.5.7/zkData（每一台服务器）
vi /opt/module/zookeeper-3.5.7/zkData/myid，填写每天服务器对应的 ID
vi zoo.cfg（每一台服务器）
# 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=/opt/module/zookeeper-3.5.7/zkData
# 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
#
# 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
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:38884、运行 Zookeeper
启动服务：每台机器执行：bin/zkServer.sh start
查看每个节点状态：bin/zkServer.sh status
四、Zookeeper 集群启动停止脚本
#!/bin/bash
case $1 in
"start"){
for i in master slave1 slave2
do
echo ----- zookeeper $i 启动-----
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh start"
done
}
;;
"stop"){
for i in master slave1 slave2
do
echo ----- zookeeper $i 停止-----
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh stop"
done
}
;;
"status"){
for i in master slave1 slave2
do
echo ----- zookeeper $i 状态-----
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh status"
done
}
;;
