CentOS Add Network card

I did a stupid thing to add a new Web card to the server, but because it couldn't be initiated,

So it's natural that CentOS 6 has many other set requirements,

So we looked up two days's information and tried many ways, but it didn't work.

This morning, I wanted to try it in the simplest way,

The result is that this is done ~ ~ ~ ~ .....

So the process is put on, one side of the vigilance of themselves, one side also let oneself smile.

1. Add a network card to confirm

A. Ifconfig

New network card will not be self-activating, so there is no IP

B. ls/etc/sysconfig/network-scripts

It's normal, no setup.

C. dmesg | Grep-in ETH

There is a network card eth1, but not up

2. Setting

A. Network Configuration

Enter setup and select "Network Configuration"

B. Device Configuration

C. New Device

See here, should know, I also want to laugh ~ ~ ~

D. Ethernet

E. Name & Device

Because I am using the Internet, I use DHCP to assign IP after I enter the name and the name of the device.

3. Finish confirming

A. Confirm that the installation has been added and stored

B. dmesg | Grep-in eth1

The network card is up

C. ifup eth1

D. ls/etc/sysconfig/network-scripts

Complete, it is so simple to complete, has been to the difficult place to think, the results in a simple way to get out ~ ~
