Crowd data center: Add a new Crowd node to the cluster ?

G'day guys,

we are planning to install Crowd Data centre and I am not clear on step 5: add a new Crowd node to the cluster

https://confluence.atlassian.com/crowd030beta/installing-crowd-data-center-907281680.html/

When installing the second server (node), do I need to install a fresh (empty) version of Crowd and then overwrite the Install and Home directories as specified by Atlassian ... or do I only need to get a server and copy / mount the relevant directories?

Quid of the reverse proxy configuration ?

 

Many thanks for your replies.

Cheers, Fred

Hi Frederic!

Thank you for asking this question.

When installing another node, you can use a fresh version of Crowd and then mount shared home directory, which should be visible to all the nodes in your cluster. The location of the shared directory mount point is $CROWD_HOME/shared (where $CROWD_HOME is the location of local crowd home directory as specified in the crowd-init.properties file or in the crowd.home system parameter)

The reason why we mentioned to copy whole installation directory from the previous node to another, was that there are certain configuration options stored in files in the installation directory, such as:

  • crowd home location
  • logging configuration (log4j.properties)

and we recommend that those options should remain the same for each node in a cluster.

I hope that this answers your question. Shall you have any further questions please do not hesitate to post them here or report an issue here or contact me directly via an email.

Your feedback about Crowd Data Center is greatly appreciated!

Hi Marcin,

Many thanks for your crystal clear reply. Your explanations make sense and we will kick off the evaluation real soon.

Cheers, Fred

Great to hear that you are now on a direct path to evaluate Crowd Data Center.

On a side note, we are also working on improving the Crowd Data Center installation documentation.

Marcin,

Are you still working on Crowd? I know this post is 2 years old but I have a question.

I have followed your instructions and I have 2 nodes running, the only small issue I have is that if I use my main URL crowd.company.com I can't tell which node I'm running on. Is there an crowd cluster gui? Or a config file I need to change in order to see which node is active for the current session. I could not find any info on that. Let me know please. Thanks.
