Install Confluence on a "JIRA core" server
Asked by mlevy5722:

We are looking for a REAL DETAILED setp by STEP install documents to help us install Confluence on a server where JIRA core is already up and running.

We cannot De-install jira core and start from beginning... This would really be counter-productive for us and would add all the data migraion head-aches....

We really need to dins th exact way and the most careful way it should be done.

HOW to :

install Confluence on a server where JIRA core is already up and running.

Thanks a million!!!

body: You are over-thinking this. The fact your server is running JIRA is irrelevant.

JIRA and Confluence are totally separate services. If I simplify your question down to the basics of what you need to ask, the answer is

1. Check the server has the resources needed to run JIRA and Confluence simultaneously

2. Install Confluence on it. (See [Installing Confluence](https://confluence.atlassian.com/doc/confluence-installation-guide-135681.html) )

Here is below why we are very confused.

After reading this article I got scared and confused:  
This is the article:

[installing-confluence-and-jira-together](https://confluence.atlassian.com/conf54/confluence-administrator-s-guide/integrating-confluence-with-other-applications/integrating-jira-and-confluence/installing-confluence-and-jira-together)

<br />

It says clearly on top and in BOLD:  
**Do not deploy multiple Atlassian applications in a single Tomcat container**

How to prevent this to happen?? We have no idea.

<br />

and then below it tells you the steps indoing JIRA core and COnfluence on same server:

Installing Confluence  
Running Confluence behind Apache  
Installing JIRA  
Integrating JIRA with Apache

We are alerady running JIRA core with Tomcat.  
So do we now have to de-install JIRA core and re-install it making sure it will use Apache instead of tomcat?

Thank you.

body: You do not have to reinstall JIRA. Confluence will install it's own Tomcat instance without interfering with JIRA's Tomcat.

An Apache proxy in front of the server is an optional mechanism for allowing access from friendly URLs (without port numbers).

body: @Ann,

Thank you for the reply.

Would you know why the documentation says in BOLD:

**Do not deploy multiple Atlassian applications in a single Tomcat container**

Does the Confluence installer does that ("use same Tomcat container" as the one used by JIRA core) by default and SO we have to somehow select an option to prevent that from happening?

IF NOT, then would an Atlassian document would try to warn us about something that can never really happen?


author: Nic Brough -Adaptavist-
body: The documentation is absolutely right, but I don't think you're quite seeing the concept of a "container".

Tomcat is an "application server", which can run many applications. It's usually referred to as a "container" when it does that.

You should not do that with JIRA and Confluence, but, more importantly, you don't need to think about it. It is now quite hard to do that. The installers all install \*independent\* containers, even on the same machine.

JIRA and Confluence are totally separate services.

1. Check the server has the resources needed to run JIRA and Confluence simultaneously

2. Install one or both on it.
