cPanel/WHM droplet clustering?

December 9, 2014 2.6k views

Is anyone using cPanel/WHM to cluster multiple droplets? I cannot seem to find anything more than references to it being done, but no details on how to do it or discussions about it.

I'd be interested in pros and cons of doing this. Does the cluster end up being a master/slave set? Does each droplet maintain its independence? What else should I be considering if I go down this road?

My main reason for wanting to do this is to simplify management of only TWO droplets at this point - but planning on perhaps adding several more in the near future.

Primary use of current droplet running cPanel/WHM is MySQL and Wordpress sites. The other droplet is running zPanel and is used for Icecast and Shoutcast streaming audio. Future droplets will likely be more WP sites.

Thanks for any input.

  • cPanel/WHM provides DNS and configuration cluster options built in which just require configuration within the control panel and the exchange of remote access keys. To the best of my knowledge there is no method available to directly make cPanel/WHM and zPanel cooperate.

  • Thanks ryanpq. To clarify, I will cease using zPanel if this configuration works. Not interested in controlling zPanel.

    Do you know if each droplet needs its own cPanel install?

  • Yes. cPanel/WHM's clustering allows you to manage multiple servers with WHM installed from a single interface. A cPanel/WHM license would be required for all of them and the cPanel/WHM software would need to be installed on each droplet in your cluster.
