Since the Ghost 1-click image is based on nginx, you should be able to follow an article that walks you through setting up Wordpress with nginx:

Let me know how it goes :]

Sorry, just to clarify:
Im not necessarily looking for easier options for the "Ghost 1-Click with nginx" compatibility,
just BEST ways/practices to do it.

Any advice here would be appreciated!

In my opinion, the best/most efficient way would be hosting Wordpress on nginx with php5-fpm. That's how I would do it personally.

Alright, thanks again Kamal. I had a look at the link you suggested.
After searching around a bit more I found some other people with similar situations as mine.
That helped me see the problem a little more clearly, I hope:

1) I have an existing wordpress website (with a lot of important content, archives etc. that needs to get transferred over to DO from my old shared host, without any hitches or screw ups by me. Ideally in the next week or so, if I can learn this stuff quickly enough.

2) I have a plan to start using Ghost for some new blogs, but no real content or anything to share as of now on those sites.

So (perhaps mistakenly?) I set up my droplet with the Ghost 1-Click install first. When I should have started with a 1-Click install of Wordpress first >>> then figured out how to set up Ghost later on...?

Would you say that the best way forward is to kill the droplet, start from scratch with a 1-Click WORDPRESS install? Then set up Ghost, nginx stuff afterwards?

Thanks for any help or suggestions you can offer.

The Ghost 1 Click image uses nginx, while the Wordpress 1 Click image uses Apache. nginx's performance is much better than Apache's so I recommend sticking with the Ghost 1 Click image and then adding in Wordpress to that droplet.

You can take a snapshot of your working droplet and then follow the article I linked. If that doesn't work, you can always restore your droplet to its "working" state from the snapshot.

Thank you, I will give it a try this weekend.
Let you know how it goes then!

@whatspo Hi I had exactly the same problem as you, this is my solution

@davsmile wow, that is a great write up, thanks!

I was able to run Ghost and Drupal in one droplet each with their own domain. I'm planning to add a wordpress site just to see how it works out.

This can be used as a reference to run Wordpress instead of Drupal. Everything was a manual install. The Digital Ocean community library was a very big help.
