the server can not connect to the web, please help me

I'm not surprised your getting an error, so am I... "Server not found", to be more precise.

Why are you still using CentOS 5.4? The latest version of CentOS is 7.4, I'd suggest you upgrade to it and use known **good** online software repositories instead.
