Question

Loadbalancer + cPanel/WHM always error 404

i have 2 droplet, 1 domain + cloudflare, 1 loadbalancer Droplet A with IP 111.111.111.111 Droplet B with IP 222.222.222.222 Loadbalancer with IP 333.333.333.333 Domain name abc.com

when i acces my domain abc.com i always get error 404, but if i point the domain to my droplet, i can access it without any error. am i missing something?

here is what i do.

Part 1 => Result in 404 (i turn off droplet B) abc.com => A 333.333.333.333 WHN in droplet A setting => current address of abc.com 111.111.111.111

Part 2 => Result in 404 (i turn off droplet B) abc.com => A 333.333.333.333 WHN in droplet A setting => current address of abc.com 333.333.333.333

Part 3 => Result in 200 OK (i turn off droplet B and ofc i didn’t use LB) abc.com => A 111.111.111.111 WHN in droplet A setting => current address of abc.com 111.111.111.111

Part 4 => Result in 404 OK (i turn off droplet B and ofc i didn’t use LB) abc.com => A 111.111.111.111 WHN in droplet A setting => current address of abc.com 333.333.333.333

Hello,

Could you please share more information about the current setup? Did you configured the cPanel/WHM servers manually or using the marketplace? Are you using any replication to sync the data/files and the database as well?

Keep in mind that load balancing, replication and high availability is not natively supported on cPanel/WHM. You can also check this link on their requested features page:

@yggitteam thank you for your valuable information.

So lsync for the files - are you using a cpanel / WHM plugin, or have you configured this manually?

How did you set up / use the database? Is it the managed DO database? or have you set up something else ?

but with email service, i don’t know much coz i dont use it…

I see - do you mind explaining what you use instead? Are you using external mail provider or you mean, you don’t worry about replicating email?

Hello @yggitteam

I would be very grateful to learn exactly how you make the two cPanel servers synchronise together.

Having a loadbalancer in front of a cluster of cpanel servers has been my wish for some time, but I am not sure how to sync the data / databases and / or email services that are all part of cpanel servers.

Thanks for sharing :-)
