Linux configuration IP Address instance description

Linux configuration IP address method;

Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Ipaddr= "192.168.x.x"
Netmask= "255.255.255.0″
Gateway= "192.168.x.x"
Vi/etc/resolv.conf

NameServer 8.8.8.8

Service Network restart

It feels a little bit messy, I'll rearrange it now.

The process of organizing the configuration is as follows:

Configuration steps:

1, run ifconfig add a ip:192.168.10.22

Command format:: Ifconfig+eth0:x + ip+netmask (subnet mask)

Ifconfig eth0:0 192.168.10.22 netmask 255.255.255.0

Note: If you want to add more, X plus 1 is OK, can support up to 255!

2, in the #cet/sysconfig/network-scripts directory to establish a corresponding eth0:0 directory and the corresponding, and modify the relevant data can!

Here we can use the CP command to do this operation

CP Ifcfg-eth0 ifcfg-eth0:0

Modify the device name, and IP corresponding! Here is a change I have a profile, you can refer to the red for the modified part!

device=eth0:0

Bootproto=static
broadcast=192.168.1.255
Hwaddr=00:00:12:62:45:16
ipaddr=192.168.1.22
netmask=255.255.255.0
network=192.168.1.0
Onboot=yes
Type=ethernet

3. Re-entry into force

Add the way the gateway operates

Modify the default gateway

Immediate effect:

Route add default GW 192.168.1.1

Start in effect:

Vim/etc/sysconfig/network-scripts/ifcfg-eth0

Join

gateway=192.168.1.1
gateway=192.168.1.1

The final results are as follows:

Device=eth0
Bootproto=static
ipaddr=192.168.1.102
netmask=255.255.255.0
geteway=192.168.1.1
Onboot=yes
Type=ethernet
