Because the company requires centos to install some panels, so when bored, I tried to install a centos, so the following error occurred.

When installing the host name, I configured ip, because eth2 was in front, I thought the NIC was above eth2 first (because there was this situation before, eht1 was before eht0, but I configured eth0, after the system installation, I found that the NIC was above 1, check the NIC command mii-tool)

After the completion of the system, I tried to ping Baidu first. After failure, I still failed after matching dns. I started to check the network card above that, but the following message appeared:

Not on cards 1 and 2, and I was instantly stunned. I want to see you." But afterwards, I also knelt down to this kind of thinking. Internet Baidu also did not find this problem, so asked our company after the technology of beautiful woman field he said to configure eth2 configuration to eth0 above to see. So change the ONBOOT of eth 2 above eth2 to no, configure eth0, restart the network card and perform a query to show the following figure.

It actually appeared! The following is a review of the 0.1 network card to see that the network card is indeed above 0

The next time this problem occurs, you can debug the network configuration, and you won't be so ignorant that you don't know where the error is..
