一、shell腳本 program.sh
#!/bin/sh
export LANG=zh_CN.GB2312
/bin/echo -e "start program!" >> /p2p.log
ps -ef|grep 'program' |grep -v grep |awk '{print $2}' |xargs -t -l kill -9
nohup /usr/java/jdk1.5.0_08/bin/java -jar /apps/program.jar 1>program.log&
啟動時sh program.sh即可
二、看門狗shell腳本 monitor.sh
#!/bin/bash
#注：本腳本需要以超級用戶身份運行。
# 監測的時間間隔，秒計
INTERVAL=60
# 重啟時間間隔
INTERVALRESTART=1
#==================================================================
PROGRAME=program
THREADNUMS=1
LOG=/apps/monitor.log
#SYSDATE=$(date)
while true
do
?? #echo " "
?? #echo "**********Now begin to monitor program's status , please wait.************"
?? #echo " "
?? #`ulimit -c unlimited`??
?? SYSDATE=$(date)
??
?? nowps1=`ps -e | grep $PROGRAME | grep -v grep | wc -l`
?? nowps1=`expr $nowps1`
???
?? #echo "ps = $nowps1"
??????
?? if? [? $nowps1 -lt $THREADNUMS ]; then
??
??????? /usr/bin/killall -9 $PROGRAME 1>/dev/null 2>/dev/null
??????? echo "======================================================" >> $LOG
??????? echo "Restart date:" $SYSDATE >> $LOG
??????? echo "Program name:" $PROGRAME >> $LOG
??????? echo "======================================================" >> $LOG
??#sleep $INTERVALRESTART????????
?????? # ./$PROGRAME 1>ucfile 2>ucfile
??????? /bin/sh /apps/server/p2pstart.sh
??????? echo " "
??????? echo "*******************************************************"
??????? echo "---------- Program $PROGRAME restart ----------------"
??????? echo "*******************************************************"
??????? echo " "
?? fi??
?? #echo "**********Now ended? monitor program's status !*************************"
?? #echo " "??
??
?? sleep $INTERVAL
??
done
#-----------------------------------------------------------
exit 0
如何在系統啟動時啟動看門狗程序：
將/bin/sh /apps/monitor.sh加入到文件/etc/rc.local中即可，這樣每次系統啟動都會運行該程序以監聽自己要監聽的程序
