@Chad nope. Redis and MongoDB are not comparable with MySQL first ahead as both are NoSQL. Additionally they also use a different port than MySQL. So basically you can install and run them without any issues.
The idea is they're compatible, although I think at the moment, it only works with 0.4.x of Ghost...
Thanks for your reply. I will try with ghost 0.4.x then.
Thank you very much.
UPDATE: I've just tested the plugin with version 0.4.2 of Ghost and all ran smoothly. The problem for me was the "Same Origin Policy" testing the plugin in my local instances of Ghost and Nodebb. I will now re-try the installation with the latest version of Ghost and let you now if i find any problem. Thanks again. 😃
UPDATE2: I've tested the plugin with version 0.5.8 of Ghost. I get an error related to the ghost API. Even logged in the api responds with 401 unauthorized. I think that is the step involved of publishing the post from ghost to nodebb (while fetching the blog entry content). Think this issue is already known by @psychobunny . Fun fact is that i can post comments en entries already published on nodebb and all works good.
