Cpanel HA Configuration with Loadbalancer

[vanilla]

Hi there

Is there a known best practise for this setup?

• 2 Servers for the same service => seen in WHM as 1 Server
• Centralised WHM Change- and Configuration Management - Modules, Services, Server Version and cPanel Version

My Idea is, that i could place bofore the 2 Servers a Loadbalancer. And when i plan to maintnance on of them, the full trafic would i redirect to server 1, when i'm on server 2 updating/change stuff. Test everything and would then to the same for server 1.

So that i got no Downtime and everything would be online for the customer.

The strange part for me would be the Data Storage, since cPanel route everything to / home. It would be quiet cool, if the Server would be separate and use the same Data Storage.

I'm currently on Azure and HA is there a thing. but don't know if cPanel support this.

You could easily sync the /home and MySQL data to make the hosted websites High available, but to make WHM/cPanel itself High available, it should be supported by the cPanel daemon which I don't think it does as of now. You may use a Virtual IP address and achieve this and have the cPanel license active on the VIP.

Hey there! There's a lot of threads discussing this if you do a search, but it's not something that's supported through any official cPanel tools just yet.

yeah i'm also on azure and got the same problem.

Well, it would be quiet handy, if we could use "Azure Files" which has a lot of nice features with like soft delete. Also creating then froum our site an easy WORM Solution into a blob storage.

I tried so many times HA with cpanel, but can't go well. Would be great if this would be supported.

This must be the one single feature where cPanel is stuck. Feature requests 80 years old now ;-)

But why does cPanel not discuss the solution offered by A U T O M 8 N - active-active-redundancy-high-availability-and-native-nginx-cpanel-plugin

Is there an official comment from cPanel on this solution / plugin ?

Yeah it would be really cool, to have WHM Servers in a cluster Setup. So that we can do updates and stuff without any issues for the users.

Sad is, that Azure supports Shared Disks. So that a.e. 2 Servers or more have the same Data Disks + on the server site epherals Disk (low costs). With Workbooks i'm then able to make Backupjobs just on the Disk Layer. That would be such a cost saving feature.

When the Cluster Setup would be supported, then would be a Autoscale Server Setup also be possible based on the load.

All I can say is that it is definitely something in our long-term goals :D I'd really like to see this too!

yeah the lovely T-rex has spoken :D

I'm still so damn happy, that cpanel will be supported with Ubuntu LTS. Love that!
