The gunman, thought to have been acting alone, is reported to have killed himself.
Authorities said there was no further threat to public safety.
Police say several of the injured are in hospital. Flights from the nearby airport are not affected.
“As officers arrived, they came into contact with an active shooting incident,” city police spokeswoman Genae Cook said, adding that it had taken place at around 23:00 local time (03:00 GMT).
“After a preliminary search of the grounds, inside and out, we have located eight people at the scene with injuries consistent to gunshot wounds. Those eight were pronounced deceased here at the scene.
A FedEx statement said the company was aware of the shooting and co-operating with the authorities.
“Safety is our top priority, and our thoughts are with all those who are affected,” it said.
Local media quoted FedEx worker Jeremiah Miller as saying he had seen the gunman firing.
“I saw a man with a sub-machine gun of some sort, an automatic rifle, and he was firing in the open. I immediately ducked down and got scared,” he said.
Last week, President Joe Biden announced his first steps since taking office to tighten gun controls following a series of mass shootings.
