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 ~ ~

Finally perfect: After the above forwarded article described the operation after the virtual machine can increase the network card, but you will find that when the virtual machine restarts after the new network card will disappear, at this time you only need to

-----------VI ifcfg-eth1 Modify Onboot=yes save and restart the Network Services service network restart
