Nginx VM

@black3dynamite Yes. Minimal. I could not find anything that gave a "best practice" on what size disk was needed. I would have been guessing honestly. What about ram?

There isn't one. NGinx just needs a few MB over the base OS. The base OS will account for 99.99% of the disk usage, and Nginx for a trivially small additional amount. You won't even really notice.

Our Fedora 29 Nginx box uses about 3.3GB of disk. If you used only 4GB, you'd be fine. But why cut it so close in this day and age?

My Nginx proxy on Vultr runs on 512MB RAM no problem. Minimal install.

It's faster if you have more. It'll cache. Here is a unit with excess RAM. I would give 1GB if you have it. Maybe not on cloud, but in a VM...

# free -m
              total        used        free      shared  buff/cache   available
Mem:           3942         392        2038           1        1511        3304
Swap:          1335           0        1335

So pretty much my minimal starting point is 20GB storage, 2GB RAM and 1 vCPU.

That's what we do. 24GB of storage thin provisioned.

512MB will work. 1GB is better. 2GB is ideal.

I think the worst part about running with 512MB is installing Fedora. That was painful, even in text mode.

Really? Been a while since I did it with that little RAM, but I do from time to time and don't remember it being any different.

Idk if it was just the process on Vultr with the custom ISO, or what, but it was bad. I think the last time I did it was Fedora 27, so it's definitely been a while.

Oh, custom ISO. Maybe I've not tried that in a few versions.

That's the only way to get true minimal right?

brandon220

Thanks for the info. I normally use 2G of ram and 2vCPU on most Fedora installs. I will give it a go. I was mostly unsure of how much resources were used between the proxy and the back-end server. Seems like it would be more but that is why I'm asking.

That's a lot. We use 1 vCPU for most installs, even in production. 2GB of RAM if you have lots of spare, maybe. But might be a little high for all systems.

Correct. The only way to get a true "anything" that isn't the cloud hosts' custom install.

brandon220

@scottalanmiller Ok. I'll try scaling back a bit and see how it goes.

Yes, using the ISO (any) of fedora 28+ is slower than hell on 512 RAM.

How do you get text mode on Fedora 28+ I don't see the menu choice.

Note: I never bothered to even Google. I just let the install chug along and do something else.

brandon220

I always use the NetInstall and do minimal. Don't see any reason not to.

So do I. But there is no text install option in the menu.

There is no difference between the ISO versions on the ungodly slow speed during the install when using 512MB RAM.

The reason to do NetInstall is to not have to turn around and do a major update right after you install. I mean you would never install from the full ISO and then not immediately run dnf upgrade would you?

Hit tab while Install Fedora 28/29 is selected, and add inst.text

Thanks. Told you I never bothered to even check the Google.

I've been giving a vm 2GB of ram to get through the install, and dropping it down to where I actually want it after it's done.

Of course, I normally deploy by cloning a snapshot, so I rarely need to go through the entire install process.
