I just used the IRFP044 as picture shows but it gets extremely hot at
8A DC. It buzzed and I saw a sine wave stacked DC at Gate. Is't
caused by the linear region resistance?

got a picture from other website:

or any other reasons?

Hard to tell without more info but why have you got a 10k resistor in the
gate drive circuit ? You should be using a few hundred ohms at most.
