I have done a silly job. I want to add a new online card to the Server, but it has never been possible,

Therefore, it is natural that CentOS 6 has additional requirements,

Therefore, I checked the materials for the past two days and found many ways, but they were not effective.

This morning, I tried my best to show it in the simplest way,

As a result, the process is completed ~~~~ Not to mention .....

As a result, you may be alert to yourself and smile.

1. Confirm after adding a network card

A. ifconfig

After a new network card is added, it will not be automatically triggered, so there will be no IP addresses

B. ls/etc/sysconfig/network-scripts

Normally, no preset timeout

C. dmesg | grep-in eth

There is a network card eth1, but there is no Up

2. Set

A. Network Configuration

Click "setup" and select "Network Configuration 』

B. Device Configuration

C. New Device

I should have known this. I also want to laugh ~~~

D. Ethernet

E. Name & Device

Because I am using the internal network, I use DHCP to allocate IP addresses after the domain name is entered and the domain name is changed.

3. Confirm

A. confirm that the database has been added and stored.

B. dmesg | grep-in eth1

The network card has been Up

C. ifup eth1

D. ls/etc/sysconfig/network-scripts

This is the completion of such a ticket. I keep thinking about it in my workshop. The result is displayed in a ticket ~~
