After investigation, the root cause is because my company uses a proxy to access the network, so the proxy also needs to be added CentOSin the configuration file :VirtualBox

(1) Add the following lines /etc/environmentin and restart the computer:

http_proxy="http://proxysrv:8080/"  
https_proxy="https://proxysrv:8080/"

or add them to the bashconfig file.

(2) also need to be added to /etc/yum.conf:

proxy="http://proxysrv:8080/"
