chmod 777 domain.key

This does not look like a good idea ..?

Maybe it would be better to change the owner of domain.key instead of opening its permissions, right?

Instead of cat cert.pem chain.pem > domain.crt, I think you can just do cp fullchain.pem domain.crt. I'd love it if someone else could confirm this though!
