what do I have to write in these fields

[bblu]

hi guys, I want to know how do I have to complete these:

• RL used to access this NodeBB (http://localhost:4567) : ¿my domain or my droplet ip? ¿which port?
• Host IP or address of your MongoDB instance (127.0.0.1): ¿my droplet ip?
• Host port of your MongoDB instance (27017): ¿and here?

ps. I have an ubuntu droplet in digital ocean + domain.
