Linux下定時重新開機Tomcat（修改）

1.寫一個shell腳本test.sh，重新啟動tomcat

#!/bin/sh

. /etc/profile

pid=`ps aux | grep tomcat | grep -v grep | grep -v retomcat | awk '{print $2}'`

echo $pid

if [ -n "$pid" ]

then

{

echo ===========shutdown================

/opt/tomcat/bin/shutdown.sh

sleep 1

pid=`ps aux | grep tomcat | grep -v grep | grep -v retomcat | awk '{print $2}'`

if [ -n "$pid" ]

then

{

sleep 1

echo ========kill tomcat==============

kill -9 $pid

}

fi

sleep 1

echo ===========startup.sh==============

/opt/tomcat/bin/startup.sh

}

else

echo ===========startup.sh==============

/opt/tomcat/bin/startup.sh

fi

2.把test.sh檔案放到root目錄下

3.提高權限

chmod a+x test.sh

4.在控制台上輸入以下指令

  crontab -e

5.按i鍵編輯這個文本檔案，輸入以下内容，每天淩晨4：30重新開機tomcat

  30 04 * * * /root/test.sh

  按esc鍵退出編輯，輸入wq回車儲存

6.啟動定時服務
