LINUX下使用Shell自动监控tomcat并且执行重启操作



脚本如下：

#!/bin/sh   # func:自动监控tomcat脚本并且执行重启操作 # author:danny # date:02/20/2013 # DEFINE   # 获取tomcat进程ID TomcatID=$(ps -ef |grep tomcat |grep -w 'dw\/apache-tomcat-7.0.34\/conf'|grep -v 'grep'|awk '{print $2}')   # tomcat启动程序(这里注意tomcat实际安装的路径) StartTomcat=/home/dw/apache-tomcat-7.0.34/bin/startup.sh #TomcatCache=/usr/apache-tomcat-5.5.23/work   # 定义要监控的页面地址 WebUrl=http://haoyayi.eyar.com   # 日志输出 GetPageInfo=/dev/null TomcatMonitorLog=/tmp/TomcatMonitor.log   Monitor() {   echo "[info]开始监控tomcat...[$(date +'%F %H:%M:%S')]"   if [ $TomcatID ];then # 这里判断TOMCAT进程是否存在     echo "[info]当前tomcat进程ID为:$TomcatID,继续检测页面..."     # 检测是否启动成功(成功的话页面会返回状态"200")     TomcatServiceCode=$(curl -s -o $GetPageInfo -m 10 --connect-timeout 10 $WebUrl -w %{http_code})     if [ $TomcatServiceCode -eq 200 ];then         echo "[info]页面返回码为$TomcatServiceCode,tomcat启动成功,测试页面正常......"     else         echo "[error]tomcat页面出错,请注意......状态码为$TomcatServiceCode,错误日志已输出到$GetPageInfo"         echo "[error]页面访问出错,开始重启tomcat"         #kill -9 $TomcatID  # 杀掉原tomcat进程         #sleep 3         #rm -rf $TomcatCache # 清理tomcat缓存         #$StartTomcat     fi   else     echo "[error]tomcat进程不存在!tomcat开始自动重启..."     echo "[info]$StartTomcat,请稍候......"     #rm -rf $TomcatCache     #$StartTomcat   fi   echo "------------------------------" } Monitor>>$TomcatMonitorLog
