How to add nginx HTTP Push Stream module through LEMP droplet

Hi,

Does anyone has successfully installed the nginx-push-stream-module in a LEMP droplet?

I need to implement a push / stream service. I decided to get an ubuntu LEMP server and install the nginx push stream module hosted by Wandenberg. I followed the Install it by yourself tutorial section written in official nginx documentation here. But the example builds a completely new nginx instance. It also does not work. I followed the instruction properly. Built and run properly. But I got an error unknown directive “push_channel_group”, which is the first “push stream” instruction nginx interprets in server config.

Is there a cleaner way to add nginx-push-stream-module in my LEMP nginx droplet’s instance, or I have to re-build nginx like it says in the documentation? Does building a new nginx instance would interfere with the default nginx instance in my droplet?

I’m a bit confused. And also relatively new with linux OS.

Thank you for your help
