集群环境：

master 192.168.1.99
slave1 192.168.1.100
slave2 192.168.1.101

下载安装包：

# Mater
wget http://archive.apache.org/dist/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz -C /usr/local/src
tar -zxvf zookeeper-3.4.10.tar.gz
mv zookeeper-3.4.10 /usr/local/zookeeper

修改配置文件：

cd /usr/local/zookeeper/conf

mv zoo_sample.cfg zoo.cfg

vim zoo.cfg

dataDir=/usr/local/zookeeper/data

dataLogDir=/usr/local/zookeeper/log

server.1=master:2888:3888

server.2=slave1:2888:3888

server.3=slave2:2888:3888

#创建临时目录和文件目录

mkdir /usr/local/zookeeper/data
mkdir /usr/local/zookeeper/log

配置环境变量：

#Master slave1 slave2

vim ~/.bashrc
ZOOKEEPER_HOME=/usr/local/zookeeper
PATH=$PATH:$ZOOKEEPER_HOME/bin

#刷新环境变量
source ~/.bashrc

拷贝安装包：

scp -r /usr/local/zookeeper/ slave1:/usr/local/zookeeper/
scp -r /usr/local/zookeeper/ slave2:/usr/local/zookeeper/

分别添加不同的ID:

#Master
echo "1" >  /usr/local/zookeeper/data/myid  
#Slave1
echo "2" >  /usr/local/zookeeper/data/myid  
#Slave2
echo "3" >  /usr/local/zookeeper/data/myid
