1.Linux下tomcat重启脚本

[root@]# vi test.sh

#!/bin/sh

export JAVA_HOME=/usr/java/j2sdk1.4.2_06/

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

echo $pid

if [ -n "$pid" ];

then

{

echo "==========tomcat is start============"

'/usr/local/tomcat/bin/shutdown.sh'

sleep 5

'/usr/local/tomcat/bin/shutdown.sh'

sleep 15

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

if [ -n "$pid" ];

then

{

echo "======to kill the tomcat pid $pid========"

kill $pid

sleep 3

}

fi

echo "==========start tomcat============"

'/usr/local/tomcat/bin/startup.sh'

}

else

{

echo "==========tomcat is stop=====start======="

'/usr/local/tomcat/bin/startup.sh'

}

fi

2.定时脚本，每天凌晨6:01执行tomcat重启脚本

[root@]# crontab -e

1 06 * * * /home/mcc/test.sh

3.启动定时服务

[root@]# service crond stop

[root@]# service crond start

4.查看该任务是否在定时列表里面：

[root@]# crontab -l

1 06 * * * /home/mcc/test.sh
