Install Nginx as a Reverse Proxy on Fedora 27

Donahue

So far, all of that external stuff has been under the "marketing" department, and I have no part of it. It also predates me at this company, probably by a decade. The marketing lady can be a PITA sometimes, so I don't want to step into that fire until I actually have to.

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?

The problem is that his entire domain is apparently outsource and not in theri control. Or this would be trivial.

It's cutting off the outsourcing that I'm trying to fix

client_max_body_size 40M;

One thing I just ran into was having to up this limit to be able to sync larger files. I would suggest flagging that in the first post so someone like me would know to change this if they work with larger files. I set mine to 16G. For some reason, this only effected the NC sync client, the browser upload as increased by other means.

Trying to get this to work tonight. The nextcloud.conf is copied on the Nginx server. I changed the server_name and the proxy_pass. Everything else is unchanged. When I run the nginx-t to verify, it returns

nginx: [emerg] invalid number of arguments in "proxy_set_header" directive in /etc/nginx/conf.d/nextcloud.conf:4
nginx: configuration file /etc/nginx/nginx.conf test failed

I have researched for a few hours and cannot "see" where the issue is. I am in need of some guidance.

You likely missed a semicolon to close a line.

@JaredBusch I looked at the config till my eyes went cross and didn’t notice that. I’ll check again later and see. I looked at the logs and they don’t really give any clues.

That error you posted tells you that. On that line you didn’t close it, so it thinks you next line is another parameter of the command.

The problem was the items such as $remote_addr did not copy at all. They were missing. The config passed. Did the certbot and all went fine. If I go to https://nc.domain.com the site loads properly. If I go to http://nc.domain.com the site redirects and loads fine. Both work and cert loads in browser. However, if I go to nc.domain.com, it returns a blank page and shows https://localhost in the browser. I have the fqdn set up on the NC server and the Nginx. Not sure where this is coming from.

Another question:
When you access Nextcloud with https and the site check shows that everything passes

But, when you place it behind Nginx, it "breaks"

I am trying to understand what is happening behind the scenes to cause the error. Is anyone else seeing this happen on their instances?

This is not broken. it is simply a warnign about something..

What do you mean broken?

brandon220

@JaredBusch I should not have said "broken". It is not causing any issues that I can see. Just not sure what changes that makes it give the warning. Is this one to ignore?

Read the message.

It says that it does not see a configuration related to LetsEncrypt.

If you are using a proxy, the proxy handles the cert.

Purely a warning, and not really a good one. It doesn't apply to you, so that makes it a bad warning.

If you want to remove that warning, add the following in the server block

location = /.well-known/carddav {
      return 301 $scheme://$host/remote.php/dav;
    }
    location = /.well-known/caldav {
      return 301 $scheme://$host/remote.php/dav;
    }

It's now 2/15/2024 with Fedora 39, and this is still working.

Just setup a new reverse proxy.
