Flume定時啟動任務 防止掛掉

一，查看Flume條數：ps -ef|grep java|grep flume|wc -l       ==》15

檢查進程：給sh腳本添加權限，chmod 777 xx.sh

#!/bin/sh
is_Engine_exist=$(ps -ef|grep java|grep flume|wc -l)
 
if [ $is_Engine_exist -ne 15 ];then
 
        echo 'flumeis down' 
        
       cd /usr/hadoop/flume/flume-server

        nohup bin/flume-ng agent -c conf/ -f /usr/hadoop/flume/spooldircsv1.conf -n a1 -Dflume.root.logger=WARN,console >>./local/run.log 2>&1 &

 
else
 
        strDate=`date +%Y%m%d%H%M%S`
 
        strRun="running ${strDate}"
