LINUX下使用Shell自動監控tomcat並且執行重啓操作



腳本如下：

#!/bin/sh   # func:自動監控tomcat腳本並且執行重啓操作 # author:danny # date:02/20/2013 # DEFINE   # 獲取tomcat進程ID TomcatID=$(ps -ef |grep tomcat |grep -w 'dw\/apache-tomcat-7.0.34\/conf'|grep -v 'grep'|awk '{print $2}')   # tomcat啓動程序(這裏注意tomcat實際安裝的路徑) StartTomcat=/home/dw/apache-tomcat-7.0.34/bin/startup.sh #TomcatCache=/usr/apache-tomcat-5.5.23/work   # 定義要監控的頁面地址 WebUrl=http://haoyayi.eyar.com   # 日誌輸出 GetPageInfo=/dev/null TomcatMonitorLog=/tmp/TomcatMonitor.log   Monitor() {   echo "[info]開始監控tomcat...[$(date +'%F %H:%M:%S')]"   if [ $TomcatID ];then # 這裏判斷TOMCAT進程是否存在     echo "[info]當前tomcat進程ID爲:$TomcatID,繼續檢測頁面..."     # 檢測是否啓動成功(成功的話頁面會返回狀態"200")     TomcatServiceCode=$(curl -s -o $GetPageInfo -m 10 --connect-timeout 10 $WebUrl -w %{http_code})     if [ $TomcatServiceCode -eq 200 ];then         echo "[info]頁面返回碼爲$TomcatServiceCode,tomcat啓動成功,測試頁面正常......"     else         echo "[error]tomcat頁面出錯,請注意......狀態碼爲$TomcatServiceCode,錯誤日誌已輸出到$GetPageInfo"         echo "[error]頁面訪問出錯,開始重啓tomcat"         #kill -9 $TomcatID  # 殺掉原tomcat進程         #sleep 3         #rm -rf $TomcatCache # 清理tomcat緩存         #$StartTomcat     fi   else     echo "[error]tomcat進程不存在!tomcat開始自動重啓..."     echo "[info]$StartTomcat,請稍候......"     #rm -rf $TomcatCache     #$StartTomcat   fi   echo "------------------------------" } Monitor>>$TomcatMonitorLog
