Linux系统在线增加多个ip

Linux系统在线增加多个ip

 

首先查看ip
代码:
linuxedu.net# ifconfig

eth0 Link encap:Ethernet HWaddr 00:50:BA:EF:21:E2
inet addr:192.168.1.1 Bcast:192.168.1.255 mask:255.255.255.0

添加ip

代码:
ifconfig eth0:0 192.168.1.2 netmask 255.255.255.255 up

在查看.
代码:
linuxedu.net# ifconfig

eth0 Link encap:Ethernet HWaddr 00:50:BA:EF:21:E2

最后写到文件里,使从新启动时生效.
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
代码:

DEVICE=eth0:0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.2


去掉ip
代码:
ifconfig eth0:0 192.168.1.2 netmask 255.255.255.255 down
rm /etc/sysconfig/network-scripts/ifcfg-eth0:0
