Ok - so the one server{} block that is used is either the one that has
server_name blog.koshie.fr, or is the default one.

Yes, and that error log shows that:

it is using the server "koshie.fr", not the server
"blog.koshie.fr". Presumably the server "koshie.fr" is the default,
and the server "blog.koshie.fr" does not exist.

So the configuration that is running, is *not* the configuration that
you are showing here.

But based on your later mail, this configuration file does not exist.

If you want to get this configured correctly, your best bet is probably
to simplify the configuration significantly.

Leave /etc/nginx/nginx.conf as it is.

Let /etc/nginx/conf.d have exactly one file in it, this one.

Then run your test and see if it works or fails.

No.

That configuration file does not result in this error.

Your test case is:

* you run "curl -i http://blog.koshie.fr/wordpress/info.php"
* you expect to see some useful content
* you actually see a 502 error.

Then do whatever it takes to get the expected output.

I think that one part of the problem is that you have only half-changed
from an old system to a new system.

You new system has nothing listening on 127.0.0.1:9000, so any
configuration that mentions that ip:port is broken. It should be removed,
or replaced with the unix socket.

And your new system does not actually include all of the files that you
want it to.

When your nginx starts, it reads exactly one configuration file:
/etc/nginx/nginx.conf.

That file then uses "include" to read some other files. Those other
files do not seem to be the ones you want, for some reason.

I suggest: stop nginx. Make sure it is stopped, and not running, and
has nothing listening on port 80 or port 443. Then look at the files
in /etc/nginx/conf.d, and make sure that they are exactly the ones that
you want. Then start nginx, access the info.php url, and see if it works.

Good luck,
