Linux下定時重啓Tomcat

1. 寫一個shell腳本test.sh，從新啓動tomcat

   #!/bin/sh   
   pid=`ps -ef | grep tomcat | grep -v grep | grep '/data1/tomcat/apache-tomcat-7.0.70/bin' | awk '{print $2}'`  
   echo $pid  
     
   if [ -n "$pid" ]  
   then  
   {  
      echo ===========shutdown================  
      /data1/tomcat/apache-tomcat-7.0.70/bin/shutdown.sh  
      sleep 1   
      pid=`ps aux | grep tomcat | grep -v grep | grep '/data1/tomcat/apache-tomcat-7.0.70/bin' | awk '{print $2}'`  
      if [ -n "$pid" ]  
      then  
       {  
         sleep 1   
         echo ========kill tomcat==============    
         kill -9 $pid  
       }  
      fi  
      sleep 1  
      echo ===========startup.sh==============  
      /data1/tomcat/apache-tomcat-7.0.70/bin/startup.sh  
    }  
   else  
   echo ===========startup.sh==============  
   /data1/tomcat/apache-tomcat-7.0.70/bin/startup.sh   
   fi

    

2. 把test.sh文件放到/data1/tomcat/apache-tomcat-7.0.70/bin目錄下
3. 提升權限

   chmod a+x test.sh

    

4. 在控制檯上輸入如下命令

   crontab -e

    

5. 按i鍵編輯這個文本文件，輸入如下內容，天天凌晨4：30重啓tomcat

   30 04 * * * /root/test.sh

    

6. 按esc鍵退出編輯，輸入wq回車保存
7. 啓動定時服務

   service crond stop
   service crond start

    

8. 查看日誌

   tail -f /var/log/cron
