这篇文章主要介绍了Shell脚本检查IP格式及mysql操作实例,本文直接给出脚本代码,需要的朋友可以参考下

还是cronjob的一部分,就是在Rails的定时任务里,后台交互运行

CheckIPAddress()
{
    echo $1 |grep "^[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}$" > /dev/null
    if [ $? = 1 ];  then
        return 1
    else
        a=`echo $1 | awk -F. '{print $1}'`
        b=`echo $1 | awk -F. '{print $2}'`
        c=`echo $1 | awk -F. '{print $3}'`
        d=`echo $1 | awk -F. '{print $4}'`
        #echo $a $b $c $d

        for loop in $a $b $c $d
        do
            if [ $loop -ge 255 ] || [ $loop -lt 0 ]; then
                return 2
            fi
        done
    fi  

}


ConfigureDefaultRegion() {
  echo "Please input Region ip"
  ret=1
  while [ $ret != 0 ]
  do
   read region_ip
   CheckIPAddress $region_ip
   ret=$?
   #echo $ret
   if [ $ret = 1 ]; then
    echo "Wrong IP address, please reinput Region IP:"
   fi
  done
  /usr/bin/mysql -u root realworx_production -e "update regions set ip='$region_ip' where id=1" 1>/dev/null 2>/dev/null
  if [ $? = 0 ]; then
          /usr/bin/mysql -u root realworx_production -e "update config_params set val=1 where ident=55" 1>/dev/null 2>/dev/null
          echo "set '$region_ip' as Default and Admin Region IP"
  else
          val=`/usr/bin/mysql -u root realworx_production -e "select id from regions where ip='$region_ip'" | awk '{if ($1 != "id") print $1}'`
          /usr/bin/mysql -u root realworx_production -e "update config_params set val='$val' where ident=55" 1>/dev/null 2>/dev/null
          region_name=`/usr/bin/mysql -u root realworx_production -e "select name from regions where ip='$region_ip'" | awk '{if ($1 != "name") print $1}'`
          echo "IP already exists. So set '$region_name' as Admin Region. "
  fi
  echo "Region Setting Successfull."
}
