乌班图配置多个ip
首先要创建一个脚本
vi 1.sh
脚本语言开始：
# !/bin/bash
touch /ip.txt
echo  "Please put in the ip ranges: "
cat>ip.txt
read -p "Please put in the network name: " WW
CC=-1
while read ips;
do
a1=`echo $ips|awk -F'/'+ '{ print $2 }'`
a2=`echo $ips|awk -F'/'+ '{ print $1 }'`
a3=`echo $a2 | awk -F. '{print $1"."$2"."$3}'`
a4=`echo ${a2##*.}`
let CC=$CC+1
let n=$a4+2

if [[ $a1 -eq 24 ]];then
for ((m=0;m<=252;m=m+1))
do
    let k=253*$CC+$m
    let y=$n+$m
    let f=$a4+1
    echo "auto $WW:$k
iface $WW:$k inet static
address $a3.$y
netmask 255.255.255.0
gateway $a3.$f
  ">>/etc/network/interfaces
  done

elif [[ $a1 -eq 26 ]]; then
for ((m=0;m<=60;m=m+1))
do
    let k=61*$CC+$m
    let y=$n+$m
    let f=$a4+1
    echo "auto $WW:$k
iface $WW:$k inet static
address $a3.$y
netmask 255.255.255.192
gateway $a3.$f
  ">>/etc/network/interfaces
  done

elif [[ $a1 -eq 27 ]]; then
for ((m=0;m<=28;m=m+1))
do
    let k=29*$CC+$m
    let y=$n+$m
    let f=$a4+1
    echo "auto $WW:$k
iface $WW:$k inet static
address $a3.$y
netmask 255.255.255.224
gateway $a3.$f
  ">>/etc/network/interfaces
  done

elif [[ $a1 -eq 28 ]]; then
for ((m=0;m<=12;m=m+1))
do
    let k=13*$CC+$m
    let y=$n+$m
    let f=$a4+1
    echo "auto $WW:$k
iface $WW:$k inet static
address $a3.$y
netmask 255.255.255.240
gateway $a3.$f
  ">>/etc/network/interfaces
  done

elif [[ $a1 -eq 29 ]]; then
for ((m=0;m<=4;m=m+1))
do
    let k=5*$CC+$m
    let y=$n+$m
    let f=$a4+1
    echo "auto $WW:$k
iface $WW:$k inet static
address $a3.$y
netmask 255.255.255.248
gateway $a3.$f
  ">>/etc/network/interfaces
  done
fi

done < ip.txt
rm -rf ip.txt
echo "*********************************************
The ips have been added successfully!
Please run "/etc/init.d/networking restart".
*********************************************"
#end
脚本语言结束
给执行权限
chmod +x 1.sh
执行：
bash 1.sh
安装服务器的ip复制进去.
(从小到大复制)

ps:ip段就不给大家详细说明
回车后， 按Ctrl-D结束
然后重启网卡即可

暂时还不知适不适用于debian
