Linux下定时重启Tomcat(修改)
1.写一个shell脚本test.sh,重新启动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文件放到root目录下
3.提高权限
chmod a+x test.sh
4.在控制台上输入以下命令
crontab -e
5.按i键编辑这个文本文件,输入以下内容,每天凌晨4:30重启tomcat
30 04 * * * /root/test.sh
按esc键退出编辑,输入wq回车保存
6.启动定时服务
[root@]# service crond stop
[root@]# service crond start
查看日志
