nginx -T

will provide you with the config that is used for the delivered version of 
nginx 1.18.0 under fedora. That's a good starting point.

  Thank you Thomas. Much appreciate this, it sounds promising. Appreciate your 
clarity.  So if I:  1. Compile nginx via `dnf install nginx` and that becomes 
my system's Nginx, installed usually in `/etc/nginx`
  2. In a totally separate folder, say, `/usr/src`, I then download a tarball 
of Nginx and compile it along with the dynamic modules -- which will produce 
the .so files for said modules
  3. Copy over the modules into the usual `/etc/nginx/modules` folder from Step 
1   ....in this sequence of steps, how do I make sure that:   A. The 
compilation in Step 2 does not become my "system's nginx" (so when I do an 
`nginx -v` at the command prompt it should be refer to the nginx installed in 
Step 1 above, and *not* the one compiled via Step 2)  B. The compile in Step 2 
will use the "same libraries" that DNF used? In the DNF version of life I 
didn't pick any libraries manually...DNF found what was on my system. Will the 
manual compile not do the same?  Many thanks!

        I'm fairly familiar with the 'compiling process' for dynamic modules - 
the process is the same for NGINX Open Source as wel as NGINX Plus. 

        You would need to compile the modules alongside NGINX and then harvest 
the compiled .so files and put them into corresponding locations on the system 
you want to load the dynamic modules. In Ubuntu, we do this (or at least, I do) 
by using the same OS and libraries as installed on the target system (as well 
as the same NGINX version). 

        This being said, **compiling** NGINX is different than **installing** 
NGINX - you can *compile* the nginx version 1.18.0 with the dynamic modules and 
the same configuration as the Fedora version, and then **take the compiled 
module** and load it up in your installed nginx instance. Compiling NGINX to 
make the dynamic module does NOT require you to then install that NGINX 
version, provided that you match the `make` steps and installed/available 
libraries to those used in the original nginx compile done in Fedora.

Thank you Miguel. But you misunderstood the question. This suggestion... 
  nginx blog as a great guide on it though 
https://www.nginx.com/blog/compiling-dynamic-modules-nginx-plus/ 
(https://www.nginx.com/blog/compiling-dynamic-modules-nginx-plus/)    
 ...misses the very first question in this thread: we cannot compile nginx from 
source on our server. At least not in a way that that compiled version would 
become the nginx installed in our *system*. We need to install nginx via the 
default Fedora dnf package manager, which at this time installs 1.18.0.  Now, 
what I don't mind doing is to compile nginx in some self-contained folder 
somewhere, then use that compilation to create the .so or whatever the module 
file for that version is....if all of this module compiling does *not* affect 
the system-installed dnf version of nginx. Is this possible?  If so, the 
instructions do not help with this. The first step in that official tutorial is 
to compile nginx and that compiled nginx then becomes the system's main nginx. 
It replaces whatever was installed via "dnf install nginx". Yes?  Hope this 
makes sense. Have I correctly understood how nginx compilation works? 
Appreciate any pointers.   Thank you.
