Linux下定时重启Tomcat

1. 写一个shell脚本test.sh，从新启动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目录下
3. 提升权限

   chmod a+x test.sh

    

4. 在控制台上输入如下命令

   crontab -e

    

5. 按i键编辑这个文本文件，输入如下内容，天天凌晨4：30重启tomcat

   30 04 * * * /root/test.sh

    

6. 按esc键退出编辑，输入wq回车保存
7. 启动定时服务

   service crond stop
   service crond start

    

8. 查看日志

   tail -f /var/log/cron
