<hr><p>由 webmaster 发布于: 2001-02-02 15:29</p><p><img src="images/icons/icon10.gif" alt="Talking" border=0> </p><p>鉴于 TOMCAT 经常出现不稳定的现象，我们必须对 TOMCAT 进行监控。
<br>monitor-tomcat.sh 作用是每秒检查一次
<br>TOMCAT 进程，如果发现 TOMCAT 进程有问题则立刻重新启动 TOMCAT 。
<br>
<br>monitor-tomcat.sh
<br>=================================================
<br>#!/bin/sh
<br>
<br>count=1
<br>while [ 1 -eq 1 ]
<br>do
<br> if [ `ps -ef | grep java | grep -v grep | wc -l` -lt 1 ]
<br> then
<br> cd /www/tomcat/bin
<br> echo "Down at:" >> /www/logs/tomcat/monitor-info.log
<br> date >> /www/logs/tomcat/monitor-info.log
<br> nohup ./startup.sh &
<br> fi
<br> sleep 1
<br> count=$count+1
<br>
<br> #if [ count -eq 900 ]
<br> #then
<br> # jpid=`ps -ef | grep java | grep -v grep | cut -c0-5`
<br> # kill -9 $jpid
<br> # count=1
<br> #fi
<br>done
<br>
<br>vi /www/tomcat/bin/delnohup
