Install Nginx as a Reverse Proxy on Fedora 27

brandon220

What is a good "size" for a VM that is strictly a reverse proxy? Would 20Gb be sufficient as it is not storing any data other than log files?

Yes. 15-20 GB is enough to run with a minimal install.

Likely just fine. I use 24GB for small servers like this. And 32GB for the big ones.

scottalanmiller

I thin provision, so a little extra is no problem for me.

wirestyle22

@scottalanmiller Yeah, thin provisioning makes sense for something like this for sure

@scottalanmiller Yeah, thin provisioning makes sense for something like this for sure

For almost everything thin provisioning makes sense. I'm sure there is an exception to the rule but I can't think of one off the top of my head.

Databases?

That would generally be it. HOWEVER, I normally put my DB on thin provisioning and have a separate, dedicated storage just for the data (DB files) which is thick provisioned.

Or if on Scale, the main storage gets a low HEAT score and the dedicated DB files gets set to 11.

It depends on how much your database grows. Then provisioning is still just fine if the database size is fairly stable

Before you can request your SSL certificate, you have to have a valid configuration file in place listening on port 80.
Nginx stores the configuration files in /etc/nginx/conf.d/, so let's make our nextcloud.conf.
I am not going to go aver all the pieces here. If you want ot know more about what all these settings mean, go look them up.
Finally, this is a sample base don Nextcloud. Change it to fit your application needs.
The structure may look strange at first, but there is a method to my madness. It is based on how certbot --nginx works.

You've got the same thing in both the server { and location / { sections. If that's not a copy/paste error, remove them from the server { section.

I figured out that step. Somehow it only pasted some of the arguments in there. I am still waiting on the DNS A record before I can move on

Why do you need an A record?

I need an external DNS record. Certbot failed because it said it needed an A record.

I've got to wait for my DNS provider to put in the record for me, which I am told will be done "sometime today". We will see, but I kinda doubt it.

How long would it take to move to a good DNS provider?

scottalanmiller

Rhetorical question, answer is "about two hours."
