1）在 hadoop102 的/home/atguigu/bin 目录下创建脚本

[atguigu@hadoop102 bin]$ vim zk.sh

在脚本中编写如下内容

#!/bin/bash

case $1 in

"start"){

for i in hadoop102 hadoop103 hadoop104

do

echo ---------- zookeeper $i 启动 ------------

ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh

start"

done

};;

"stop"){

for i in hadoop102 hadoop103 hadoop104

do

echo ---------- zookeeper $i 停止 ------------

ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh

stop"

done

};;

"status"){

for i in hadoop102 hadoop103 hadoop104

do

echo ---------- zookeeper $i 状态 ------------

ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh

status"

done

};;

esac

2）增加脚本执行权限

[atguigu@hadoop102 bin]$ chmod u+x zk.sh

3）Zookeeper 集群启动脚本

[atguigu@hadoop102 module]$ zk.sh start

4）Zookeeper 集群停止脚本

[atguigu@hadoop102 module]$ zk.sh stop
