LOL... this thread is funny. A computer illiterate person complaining about not having support on a free product. Try buying a 2nd-hand cisco switch and calling cisco to help set that up for you... good f*cking luck XD
How about I help you? for a fee of course... my field is IT, but I don't do it for free. Hence it is called a job, where people pay for my knowledge and expertise. I am not a developer though, so that is why I reserve those types of questions for them. However, I am learning to become a full stack developer... just for kicks.
OOOORRRRR.... learn how to use the OS first, before going on a pointless hissy-fit and hoping to get support from people. If it is about setting up nodebb as a service on linux... the instructions work. Unfortunately one will have to do the hard work (aka reading and following the instructions). A couple of modifications here and there (if you know what you are doing) and presto, it works beautifully. Haven't had it crash once... except for nginx... but I fixed that.

took me 2 seconds to search it on this forum...
