Running Proxmox for web application server (multiple mysql databases + php)

[promoxer]

I used to get a 2nd exact same motherboard (typically 2nd hand too) as a backup, i.e. "fallback" and basically have a spare set HDD (now SSD) since they are the part that degrade fastest. Monitors too.

Thanks for the replies.
We are thinking about having 2 additional servers.

1 main server on the office,
1 server in my college's home
1 server in my home

If the main server goes down, one of the other servers can be used as fallback and if that goes down the 3rd can be used as fallback.
Is this correct?

And how does it work with ip addresses. The webdomain goes to my office IP address. If that server goes down (or the network goes down), do i manually need to update my ip address in the DNS record?

Also i am thinking of installing 3CX on the server for my phone connection.
Could this be synced as well, so if 1 server goes down my phone system stays online?

Keep in mind that you want a low latency for your cluster. So a node at home may not work in case the latency is too high. Recommended would be <1ms but might work a bit higher.

But having 3 servers in my office wouldn't help if internet or power goes down.
A UPS could help with power outage but that can't keep the system running for hours

What would happen if latency is too high?

It may corrupt corosync synchronization, quorum lost, etc.

I run everything in my house. I have never been hosted and have always self-hosted since 1995.

My advice is to do it yourself. you may even end up provisioning for others. Experience is the best teacher. Do not be put off by those hyper.

I have about six servers like your specs e.g. Dell R720, R620, some 128GB, some 64GB, etc...

I have been running all my online teachings, website, self-hosted git, CVS, etc... for many decades.

You have made the best and right decision by going self-hosted.

Get Servers with H310 card or HBA for your storage.

Don't look back, go for it and take from there.

God blesses!!!
