Also, a few things I noticed:
If you leave port=5984 on [httpd] then mochiweb crashes with eaddrinuse. I guess it's try to setup 2 web servers? Commenting out the port=5984 on httpd fixes that.
If you try to change the ssl port to 443, couchdb crashes with this error:
[error] 2017-05-08T15:59:47.105266Z couchdb@localhost <0.213.0> -------- Failure to start Mochiweb: eacces
It works fine on port 6984 though
I am trying to change the port because I'm trying to use LetsEncrypt for my SSL, which requires 443
