Setting up Nginx on CentOS 7 as a reverse proxy

Obsolesce

You use multiple server config areas in your example code, and then server_name and proxy_pass for each site using different ports.

@tim_g So essentially what I did above, correct?

I'll find a good link to reference, I can't do this on my phone... gimme a few mins.

@tim_g Np. Thanks

I prefer to have each server block for each domain/subdomain in it's own config file.

Like this, this is a good example of what I meant...

@jaredbusch Understood. Thanks. I bet multiple configs makes it easier organizationally and also when troubleshooting so you have less to go through.

That is my preference, yes.

Not really. Just everything is broken out.

So I ran into this

but the nginx documentation here points to this: https://nginx.org/en/docs/http/server_names.html

Is there an error here I'm not seeing? I mean, there must be. Each time I make a change I systemctl reload nginx

Actually I think I figured it out. made a mistake with the .conf files

@wirestyle22 Share your resolution if you will. I was trying to install nginx on a server with wiki.js the other day and was running into the same error.

I never run certbot with one of the specific switches like --nginx or --apache. Ever.

Fuck letting some 3rd party script edit my configuration files.

I run in standalone mode and edit the conf files myself.

I also include multiple SAN on my certs, so the same SSL file is in multiple conf files.

But doesn’t ‘certonly’ keeps it from editing the files?

LOL - JB doesn't trust scripts from LE or whomever made them, but he for some reason trusts other people's scripts.... LOL
