ZK集群启动停止脚本

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

#! /bin/bash

case $1 in
"start"){
	for i in hadoop102 hadoop103 hadoop104
	do
		ssh $i "/opt/module/zookeeper-3.4.10/bin/zkServer.sh start"
	done
};;
"stop"){
	for i in hadoop102 hadoop103 hadoop104
	do
		ssh $i "/opt/module/zookeeper-3.4.10/bin/zkServer.sh stop"
	done
};;
"status"){
	for i in hadoop102 hadoop103 hadoop104
	do
		ssh $i "/opt/module/zookeeper-3.4.10/bin/zkServer.sh status"
	done
};;
esac

2）增加脚本执行权限

[atguigu@hadoop102 bin]$ chmod 777 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
