交流一些比较实际的问题--Tomcat 性能优化问题

我的Tomcat 每晚必当掉一次
实在是找不到好的办法，写了一个shell，监视它，如果当掉就重启
无法通过shutdown.sh关，只能kill pid

wget -q -O - -T 10 --tries=1 http://localhost | grep -q xxx.abc.com
取一个关键字比如是域名，如果下取不到的话，则可以确定tomcat停止了响应(tomcat当掉或成为僵死进程),取出错误的日志(最后200行)发送到到xxx,再执行kill进程，启动tomcat

/usr/local/bin/reboot_tomcat.sh

#!/bin/bash
DIR=/opt/tomcat

cd $DIR
$DIR/bin/shutdown.sh
sleep 3
ps -ef |grep tomcat/bin/bootstrap.jar |grep -v grep|awk '{print $2}'|xargs kill -9

export  JAVA_HOME=/usr/local/jdk
export  CLASSPATH=$CLASSPATHJAVA_HOME/libJAVA_HOME/jre/lib
export  PATH=$JAVA_HOME/binJAVA_HOME/jre/binPATHHOMR/binANT_HOME/bin

$DIR/bin/startup.sh

exit 0
