How to configure centos6.5 Bridging Mode for Internet access in virtualbox

I remember that I was able to access the Internet right away when I installed the Bridge Mode for Linux. After I reinstalled the system on the virtual machine, I couldn't access the internet. After several times, I kept installing the system. How should I configure it, I have forgotten it. I am too old to be confused! Record it here so that you do not forget it next time.

 

1. install Linux and configure the IP address. Set the virtual machine to the bridging mode. For example, select the host Nic in the red box. Here is the NIC of my win7 computer.

2. Modify the network connection attributes. For example, check the settings and click OK.
