Unknown directive: "passenger_enabled" in nginx.conf server block

[daBee]

Question 1: What is the problem?
I cannot get nginx to start due to a directive:

nginx: [emerg] unknown directive "passenger_enabled" in /etc/nginx/conf.d/example.conf:22
nginx: configuration file /etc/nginx/nginx.conf test failed

That's in the server block:

passenger_enabled     on;

Question 2: Passenger version and integration mode:
Passenger processes:

rich        5581  0.0  0.0   3876  2024 pts/0    S+   20:27   0:00 grep Passenger

passenger status:

Now that I have passenger.conf loading, its first directive throws an error:

nginx: [emerg] unknown directive "passenger_root" in /etc/nginx/conf.d/passenger.conf:1

Here is that file:

passenger_root /usr/share/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /home/user3/.rbenv/shims/ruby;
passenger_instance_registry_dir /var/run/passenger-instreg;

Also this file does not exist:

load_module /usr/lib64/nginx/modules/ngx_http_passenger_module.so;

Is the passenger Nginx module package installed or just the passenger package?

[daBee]

It is not installed. But...

nginx version: nginx/1.20.1

That's due to a change to which nginx package we build against. Our users were very insistent that they didn't like us building against the default nginx, and would prefer the newest possible. The steps to migrate are here: #2485
