由于服务器上一些进程莫名的挂掉,需要些一个monitor的bash脚本来监控这些进程:

#! /bin/bash
#chkconfig info
### BEGIN INIT INFO
# Provides:
# Default-Start:
# Default-Stop:
# Description:
### END INIT INFO
MYSQL_NAME='mysql'
APACHE_NAME='http'
function check_process {
search_string=$
search_result=`nmap localhost|grep -P $'$'|awk '{print $3}'|grep $search_string`
echo $search_result
if [ "$search_result" = "$search_string" ]
then
echo $"Still exist!"
else
echo $"Not exist!"
/opt/lampp/lampp start >> /dev/null
echo $"Lampp restart!"
echo $"Lampp stop unexpectedly, now it restart by cron!" | mail -s "Breamweb error!" @.com
fi
}
case "$1" in
start)
/opt/lampp/lampp start
;;
stop)
/opt/lampp/lampp stop
;;
monitor)
check_process $MYSQL_NAME
check_process $APACHE_NAME
;;
esac
exit 0
crontab:
*/1 *  * * * /etc/init.d/ monitor >> /var/log/cron..monitor.log 2>&1
