In brief: Cytokines

Inflammatory processes cause release of cytokines that reset the thermostat in the brain to a higher level causing fever.
Rigor/chills/shivering are body's effort to raise the temperature by generating heat from working the muscles. So rigor and fever are both driven by cytokines.
