When I removed the old porch light, I found there was no ground wire
from the house and the ground from the light fixture was just loose.
There are just a white wire and a red wire coming from the house. The
new fixture has a black wire, a white wire and a ground.

How do I proceed?

Thanks.

Black to red, white to white.

You have no ground available so leave it as the old fixture was unless
you want to pull a ground from the house panel.

If it's an older house and the light and wiring were put into place
before grounding was required by code, you can just replace it
without ground by hooking up the white wire to white and red to
black. If ground was required by code at the time and it was put in
incorrectly, then it should be corrected by running a wire with ground
to it.

Yes, it's a concrete block house almost 50 years old..

Thanks to both posters for the info.

You might want to consider installing a fixture that doesn't have any
exposed metal parts. It will be marginally safer.

Obvioiusly, the best approach is to replace the cable with a grounding
cable. Alternatively, you can install a GFCI on the circuit. This will
provide protection against electrocution that's superior to that provided by
a "proper" ground connection.
