監控tomcat多個進程腳本

葉總給的腳本。

某應用系統在試運行期間，WEB端經常退出，為保證系統的應急響應，將WEB端部署成了5個節點，分別為zjgpwebnode1～5，并執行了監控進程：

一、創建監控執行腳本文件/home/monitor.sh，內容如下：

SHELL=/bin/bash

LANG=zh_CN.GB18030

SUPPORTED=zh_CN.GB18030:zh_CN:zh_CN.UTF-8:zh:en_US.UTF-8:en_US:en

LD_LIBRARY_PATH=/lib:/usr/lib:/lib64:/usr/lib64

export LANG

export SUPPORTED

export LD_LIBRARY_PATH

su - root >> /home/resetlog.log

LANG=zh_CN.GB18030

SUPPORTED=zh_CN.GB18030:zh_CN:zh_CN.UTF-8:zh:en_US.UTF-8:en_US:en

LD_LIBRARY_PATH=/lib:/usr/lib:/lib64:/usr/lib64

export LANG

export SUPPORTED

export LD_LIBRARY_PATH

WEBLOGIC1=`ps -ef|grep -c Dweblogic.Name=zjgpwebnode1`

WEBLOGIC2=`ps -ef|grep -c Dweblogic.Name=zjgpwebnode2`

WEBLOGIC3=`ps -ef|grep -c Dweblogic.Name=zjgpwebnode3`

WEBLOGIC4=`ps -ef|grep -c Dweblogic.Name=zjgpwebnode4`

WEBLOGIC5=`ps -ef|grep -c Dweblogic.Name=zjgpwebnode5`

WEBLOGIC6=`ps -ef|grep -c Dweblogic.Name=myserver` 

if [ $WEBLOGIC1 != "2" ] ; then

date >> /home/resetlog.log

echo "Now Node1 is down!" >>/home/resetlog.log

locale >> /home/resetlog.log

set >> /home/resetlog.log

echo "Restart Node1 start" >>/home/resetlog.log

cd /home/weblogic/bea/user_projects/domains/webcluster/

nohup ./startManagedWebLogic.sh zjgpwebnode1 >1.out &

else

echo "Node3 is OK!" >>/home/resetlog.log

fi

if [ $WEBLOGIC4 != "2" ] ; then

date >> /home/resetlog.log

echo "Now Node4 is down!" >>/home/resetlog.log

locale >> /home/resetlog.log

set >> /home/resetlog.log

echo "Restart Node4 start" >>/home/resetlog.log

cd /home/weblogic/bea/user_projects/domains/webcluster/

if [ $WEBLOGIC6 != "2" ] ; then

date >> /home/resetlog.log

echo "Now TimerNode is down!" >>/home/resetlog.log

echo "Restart Timer Node start" >>/home/resetlog.log

cd /home/weblogic/bea/user_projects/domains/zjgpwebtimer

nohup ./startWebLogic.sh >> /home/logs/timer-web.log &

echo "Restart Timer Node end" >>/home/resetlog.log

else

date >> /home/resetlog.log

echo "Timer Node is OK!" >>/home/resetlog.log

fi

exit

請注意，該文件必須采用UltraEdit來編輯，并且保存時必須選擇為unix格式進行保存，主要是回車換行符的問題，否則匯報“syntax error: unexpected end of file”錯誤；

在實際執行時發現，采用crond系統計劃任務的方式進行運行時，環境變量與原來的root用戶登錄時不一致，導致系統有亂碼產生，故在腳本中增加了業務系統運行所需的環境變量；

二、創建好monitor.sh文件后，必須在計劃任務中添加該執行任務：

執行：crontab -e，添加

*/20 * * * * /home/monitor.sh

注：意思為每20分鐘執行一次監控程序monitor.sh

三、添加完成后重啟計劃任務程序以使計劃任務生效：

/sbin/service crond restart
