linux进程监控，monitor脚本

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:
