hadoop实用组件启停脚本

1）在hadoop102的/home/mars/bin目录下创建脚本

[mars@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 "------------- $i -------------"

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

    done
};;

"stop"){

    for i in hadoop102 hadoop103 hadoop104

    do

        echo "------------- $i -------------"

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

    done
};;

"status"){
    for i in hadoop102 hadoop103 hadoop104

    do
        echo "------------- $i -------------"

        ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh status"
    done
};;
esac

2）增加脚本执行权限

[mars@hadoop102 bin]$ chmod 777 zk.sh

3）Zookeeper集群启动脚本

[mars@hadoop102 module]$ zk.sh start

4）Zookeeper集群停止脚本

[mars@hadoop102 module]$ zk.sh stop
