First step - check the engine oil level and refill as necessary. Be sure the check with the engine cold and turned off.
Once the engine oil level is full, and if the knocking is still there, then investigate the source. Open the hood and with a helper - start the engine, to determine the noise location.

Too many possibilities to list without further investigation - almost impossible to give any direction via the internet until more information is known and testing is performed.
