ubuntu 批量添加 IP

针对整个C段IP一次性添加的方式
新建批量IP脚本文件
sudo vi /opt/ip1.sh

#!/bin/bash
for ((i=0;i<=254;i=i+1))
do
echo "auto enp2s0:$i">>/etc/network/interfaces
echo "iface enp2s0:$i inet static">>/etc/network/interfaces
let j=$i+1
echo "address 192.168.1.$j">>/etc/network/interfaces
echo "netmask 255.255.255.0">>/etc/network/interfaces
#echo "gateway 192.168.1.1">>/etc/network/interfaces
echo " ">>/etc/network/interfaces
done
# end

ubuntu 批量添加
针对多C段的IP添加方式，i填入网卡不重复起始数字，j填入IP的开始数字
#!/bin/bash
#i is iface, j is ip
j=162
for ((i=194;i<=223;i=i+1))
do
echo "auto enp2s0:$i">>/etc/network/interfaces
echo "iface enp2s0:$i inet static">>/etc/network/interfaces
echo "address 192.168.1.$j">>/etc/network/interfaces
echo "netmask 255.255.255.0">>/etc/network/interfaces
#echo "gateway 192.168.1.1">>/etc/network/interfaces
echo " ">>/etc/network/interfaces
let j=$j+1
done
# end

执行批量IP脚本文件
sudo bash /opt/ip1.sh

重启网卡绑定IP
sudo  /etc/init.d/networking restart

查看已添加的IP
