云服务器：linux系统添加和删除IP，批量添加IP

time

首先输入root,密码进入

再查看IP网卡，命令：ifconfig

xinknat# ifconfig

显示：

eth0 Link encap:Ethernet HWaddr 00:30:18:A1:A9:4A

inet addr:98.126.33.66 Bcast:98.126.33.71 Mask:255.255.255.248

输入:" ifconfig eth0:2 98.126.33.69 netmask 255.255.255.248 up "

再输入:“vi /etc/sysconfig/network-scripts/ifcfg-eth0:2 "

DEVICE=eth0:2

ONBOOT=yes

BOOTPROTO=static

IPADDR=98.126.33.69

保存，按Esc退出，输入" : wq "在输入"shift+! "然后回车成功。

重启网络让IP生效： service network restart

cat /etc/sysconfig/network-scripts/eth0:2 查看更改生效了不

附删除ip方法

代码:

ifconfig eth0:2 98.126.33.69 netmask 255.255.255.248 down

rm /etc/sysconfig/network-scripts/ifcfg-eth0:2

------------------------------------

1.添加虚拟ip

ifconfig eht0:1 192.168.100.22 netmask 255.255.255.0

2. 删除刚才添加的虚拟IP

ip addr del 192.168.100.22/24 dev eth0

--------------------------------------------------

单网卡批量添加不同IP段

70.39.112.194 添加IP:70.39.112.195-222/70.39.83.226-254

代码:

vi /etc/sysconfig/network-scripts/ifcfg-eth0-range0

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR_START=70.39.112.195

IPADDR_END=70.39.112.222

CLONENUM_START=0

GATEWAY=70.39.112.193

NETMASK=255.255.255.224

NO_ALIASROUTING=yes

service network restart #重启网卡

-------------------------------------------------------------

ifconfig 后 看到 IP:70.39.112.195-222 对应网卡号:eth0:0-eth0:27,

所以再批量添加IP，网卡从eth0:28以后开始就行,

网卡eth0不变，创建新文件:ifcfg-eth0-range1

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

vi /etc/sysconfig/network-scripts/ifcfg-eth0-range1

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR_START=70.39.83.226

IPADDR_END=70.39.83.254

CLONENUM_START=28

GATEWAY=70.39.83.225

NETMASK=255.255.255.224

NO_ALIASROUTING=yes

重启网络让IP生效： service network restart
