Hardware crashed. How to build a active-passive redundancy with Confluence ?

Michael Regelin

Hello,

Our Server has just crashed two days ago.

This situation shows the limit of our environment.

We would like to build a new environment where server A is active (up) and server B is asleep (down all the time).

When server A crash. I turn on server B.

This process puts a lot of questions in mind:

What about the datastorage ? can I switch from server A to B transparently?

What about licence ? can I switch from server A to B without having problem ?

As Confluence is not a critical application, we dont wont to have an active cluster configuration, despite it would only be a high availability solution...

I would appreciate for help about this situation.

Thanks.

Michael

Hi,

I have just done this for Confluence and JIRA - but of cause with a running standby server, simply with rsync for files in /pack/confluence-data and /pack/confluence - and mysqlsump for the database.

Then a simple script on the standby server to:

1. Drop and create new database

2. Import mysqldump file

3. Start Tomcat on the server

The frequency of the rsync and mysqldump desides how close to real-time data You have. A master-slave MySQL solution is also possible.

Other posibilities could be have Veeam doing it (as You server is virtual I suppose)

Thanks Normann,

Sorry for answering so late. I had read your post before but forgot to mark your response.

Thanks also for the Veeam solution.

The Rsync is what we have choosen and a simple oracle restore from our backup solution.

Works great.

It does, primary things we need to "change" is the server.xml files as there is no Load Balancer or public URLs for the copy version, it is contacted direcly on hostname with http.

Besides that, is pretty KISS :-)
