nginx did not start upon system reboot. tried to manually start it in the terminal. received the following errors. what do they mean, and how do I fix it so that nginx starts?

Found the answer:

In /var/log/ there wasn't an nginx folder.

I added an nginx folder to /var/log/ so that the /var/log/nginx folder is present and usable.
