Planck distribution in a Rindler spacetime has been calculated as an example of boson gas equilibrium under acceleration/gravitation. It is known that local temperatures of a matter in acceleration/gravitation are not uniform since energy (=mass) is subject to its effect. This causes difficulty in calculating a boson gas equilibrium since bosons are waves spread over the cavity and not localized. A global temperature is introduced, which is based on the conserved quantities resulting from the Killing flow, to overcome this difficulty in the present paper; the Planck distribution is successfully obtained.
