@PitaJ thank you very much for the reply!
1.) Can you advice me which user should I use to go through the installation process? www-data? root? other?
I suggest creating a new
nodebb user with a home directory and installing NodeBB into a folder in
nodebb's home directory.
Please don't install or run NodeBB as root.
2.) Does it matter which user runs the command "./nodebb start" after successful setup?
Yes, due to file system ownership and permissions. You should run
./nodebb start as the
nodebb user if you follow my previous suggestions.
Does user mentioned in points nr (1) and (2) really matter as the service will be available anyway on http://localhost:4567?
Only in the "don't use root" sense. Otherwise it doesn't really matter.
