zookeeper脚本启动方式（一次启动多台）

1. 首先下载sshpass为了免密

   yum install sshpass

2. 随后到/home/用户名/bin中，没有就新建
3. 新建文件vim zk.sh,粘贴下面脚本

#!/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 关闭 -------------------
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

4.执行权限

sudo chmod +x zk.sh

5.然后去103，104同样的操作执行上面的，随后大功告成！！！
