Configure multiple IP addresses in linux

Configure multiple IP addresses in linux

The Red Hat Linux is used as an example. Assume that the original system has configured an IP Address: 192.168.0000140, the configuration file path/etc/sysconfig/network-script/ifcfg-eth0. Now you need to configure an IP address with the network segment 192.168.1.

STEP (root user permission required ):

1, cp/etc/sysconfig/network-script/ifcfg-eth0/etc/sysconfig/network-script/ifcfg-eth1

2, vi/etc/sysconfig/network-script/ifcfg-eth1 to modify the black part, colon plus 1

DEVICE = eth0: 1
BOOTPROTO = none
ONBOOT = yes
HWADDR = 00: 0c: 29: ee: a6: 11
NETMASK = 255.255.255.0
IPADDR = 192.168.1.140
TYPE = Ethernet
USERCTL = no
IPV6INIT = no
PEERDNS = yes

3. The service network restart takes effect for the modified configuration.

4. View through ifconfig. Then, you will see an additional eth1 IP configuration.
