How to add Confluence to my existing self-hosted JIRA instance?

[Brogan Beard]

I have JIRA Service Desk.  How do I add Confluence to my self-hosted instance of JIRA?

Do I need to deploy a new server to host Confluence and connect it to the JIRA database on the server where Service Desk is hosted?

Edit: typo.

JIRA and Confluence are two separate systems. 

You will need to install Confluence as a separate thing to JIRA.

(Technically, you could run them in the same Tomcat server.  But never do that - it *will* break, in bad ways)

My dev setup has JIRA and Confluence running as two independent installations, but on the same physical server (if you're going to do that, make sure it has enough CPU and memory for both).  You could just as easily run them on totally separate machines, and most people do that.

Running them separately has no bearing on how you connect them with each other with application links and so-on.

On the database side, it's more common to see one database server behind the two services.  But they must be run in separate databases.  My PostGres server is running a single database service, but I've got the JIRA, Confluence, Crowd and Bitbucket databases (and others) all inside it.

Thanks for the information that is very helpful.  In this case, I plan to have Confluence run on its own separate VM from JIRA, but I am still a bit confused and I think it's just me not understanding the difference between the systems.

When I purchased and installed JIRA Service Desk, I thought I installed JIRA, then installed Service Desk.  Are JIRA (core) and JIRA Service Desk two separate systems? Meaning just because I purchased JIRA Service Desk doesn't mean I purchased JIRA?
