CDH版本的zookeeper环境搭建

CDH版本的zookeeper环境搭建

1.下载，解压
下载地址为：
http://archive.cloudera.com/cdh5/cdh/5/
我们这里也下载对应版本的CDH5.14.0这个版本的zookeeper的压缩包即可

2.修改配置文件
node01修改配置文件
创建zk数据存放目录

mkdir -p /export/servers/zookeeper-3.4.5-cdh5.14.0/zkdatas

修改zk配置文件

cd /export/servers/zookeeper-3.4.5-cdh5.14.0/conf 
cp zoo_sample.cfg zoo.cfg
vim  zoo.cfg

dataDir=/export/servers/zookeeper-3.4.5-cdh5.14.0/zkdatas
autopurge.snapRetainCount=3
autopurge.purgeInterval=1
server.1=node01:2888:3888
server.2=node02:2888:3888
server.3=node03:2888:3888

创建myid文件并写入内容

echo 1 > /export/servers/zookeeper-3.4.5-cdh5.14.0/zkdatas/myid

将安装包分发到其他机器
node01执行以下命令

cd /export/servers
scp -r zookeeper-3.4.5-cdh5.14.0/ node02:$PWD
scp -r zookeeper-3.4.5-cdh5.14.0/ node03:$PWD

node02修改配置文件
node02执行以下命令

echo 2 > /export/servers/zookeeper-3.4.5-cdh5.14.0/zkdatas/myid

node03修改配置文件
node03执行以下命令

echo 3 > /export/servers/zookeeper-3.4.5-cdh5.14.0/zkdatas/myid

3.启动zk服务
三台服务器启动zookeeper，三台机器都执行以下命令启动zookeeper

cd  /export/servers/zookeeper-3.4.5-cdh5.14.0
bin/zkServer.sh start

4.一键启动和关闭zookeeper
startZookeeper.sh

#!/bin/sh
echo "启动zookeeper中...."

for host in node01 node02 node03
do
        ssh -q $host "source /etc/profile; /export/servers/zookeeper-3.4.5-cdh5.14.0/bin/zkServer.sh start"
done

echo "启动zookeeper完成....."

shutdownZookeeper.sh

#!/bin/sh

echo "关闭zookeeper中...."
for host in node01 node02 node03
do
        ssh -q $host "source /etc/profile; /export/servers/zookeeper-3.4.5-cdh5.14.0/bin/zkServer.sh stop"
done

echo "关闭zookeeper完成....." 

记得 source /etc/profile重载生效
