为什么flume无法使用启动脚本运行？

如何解决为什么flume无法使用启动脚本运行？

运行命令时水槽成功运行

/opt/module/flume/bin/flume-ng agent --conf /opt/module/flume/conf --conf-file /opt/module/flume/conf/file_flume_kafka.conf --name a1 -Dflume.root.logger=INFO,console

[root@master bin]# jps
12193 Application
10259 QuorumPeerMain
12310 Jps
10751 Kafka

但是当我运行编写的启动脚本时，该脚本不起作用。脚本如下：

#! /bin/bash
case $1 in
"start"){
        for i in master slaves01
        do
                echo " --------启动 $i 采集flume-------"
                ssh $i "/opt/module/flume/bin/flume-ng agent --conf /opt/module/flume/conf --conf-file /opt/module/flume/conf/file_flume_kafka.conf --name a1 -Dflume.root.logger=INFO,console"
                echo "-------运行完命令-----------"
            done
};;
"stop"){
        for i in master slaves01
        do
                echo " --------停止 $i 采集flume-------"
                ssh $i "ps -ef | grep file_flume_kafka | grep -v grep |awk '{print \$2}' | xargs kill"
        done
};;
esac

控制台显示：

[root@master flume]# f1.sh start

输入“ jps”：

[root@master bin]# jps
10259 QuorumPeerMain
12539 Jps
10751 Kafka
[root@master bin]#

我正在网上搜索很长时间。但是没用。请帮助或尝试提供一些解决方法。
