linux脚本后台监控执行指定程序的状态(假设程序是死的重新启动程序)

#!/bin/sh

while true

do

ps | grep "main_3g" | grep -v "grep" > /dev/null

if [ "$?" -ne 0 ]

then

ls /root/main_3g > /dev/null

if [ "$?" -eq 0 ]

then

chmod 777 /root/main_3g

/root/main_3g &

echo "main_3g restart"

else

echo "main_3g is not exist."

fi

fi

ps | grep "main_4g" | grep -v "grep" > /dev/null

if [ "$?

" -ne 0 ]

then

ls /root/main_4g > /dev/null

if [ "$?" -eq 0 ]

then

chmod 777 /root/main_4g

/root/main_4g &

echo "main_4g restart"

else

echo "main_4g is not exist."

fi

fi

sleep 5

done

把上面的脚步执行命令加入到/etc/rc.d/rc.local里即可了，在后面加入

ls /root/mymonitor.sh > /dev/null

if [ "$?

" -eq 0 ]

then

chmod 777 /root/mymonitor.sh

/root/mymonitor.sh &

echo "run /root/mymonitor.sh"

else

echo "/root/mymonitor.sh is not exist."

fi
