How to setup Nginx+RTMP live stream server

IMPORTANT UPDATE! These guide may be outdated. Please see the new guide here:
http://www.ustoopia.nl/featured/nginx-rtmp-hls-ssl-videojs-on-ubuntu-18-04/
AN EVEN MORE IMPORTANT UPDATE! This is the most recent guide I've put together: https://livestream.puntenel.nl/knowledge-base/create-a-secure-adaptive-bitrate-hls-stream-with-nginx-rtmp-ffmpeg-videojs-on-ubuntu-20-04/

I made a couple of Youtube video's with some instructions on how to setup your own private live-stream server using Nginx running on Ubuntu 18.04. . Click on the CONTINUE READING link below to see a copy of the variables that I used in the video's. You can also find it on my Pastebin if you prefer.

I'm assuming you have already installed Ubuntu 18.04. If not, please have a look at this following video first.

FIRST INSTALL THESE USEFUL / REQUIRED PACKAGES

sudo apt-get install wget unzip software-properties-common dpkg-dev git make gcc automake build-essential zlib1g-dev libpcre3 libpcre3-dev libssl-dev libxslt1-dev libxml2-dev libgd-dev libgeoip-dev libgoogle-perftools-dev libperl-dev pkg-config autotools-dev gpac ffmpeg mediainfo mencoder lame libvorbisenc2 libvorbisfile3 libx264-dev libvo-aacenc-dev libmp3lame-dev libopus-dev unzip

ADD THE NGINX REPOSITORY AND UPDATE

sudo add-apt-repository ppa:nginx/stable
apt update

INSTALL NGINX

sudo apt install nginx

INSTALL THE RTMP MODULE

sudo apt install libnginx-mod-rtmp

CLONE THE RTMP GIT

cd /usr/src
git clone https://github.com/arut/nginx-rtmp-module

COPY THE STAT.XSL FILE TO YOUR WEB FOLDER

cp /usr/src/nginx-rtmp-module/stat.xsl /var/www/html/stat.xsl

CREATE A NEW FILE CALLED CROSSDOMAIN.XML IN YOUR WEB FOLDER

nano /var/www/html/crossdomain.xml

PASTE THIS IN THE NEW FILE AND SAVE IT

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*"/>
</cross-domain-policy>

EDIT THE NGINX CONFIG FILE

nano /etc/nginx/nginx.conf

AT THE END OF THE FILE ADD THIS

rtmp {
	server {
	listen 1935;
	chunk_size 4096;

	application live {
		live on;
		record off;
		interleave off;
		wait_key on;
		meta on;
		wait_video off;
		idle_streams off;
		sync 300ms;
		session_relay on;
		#allow publish 127.0.0.1;
		#allow publish 192.168.2.0/24;
		allow publish all;
		#deny publish all;
		allow play all; 

# EDIT THESE SO THE LIVESTREAM_KEY IS REPLACED BY YOUR PERSONAL KEY THAT YOU CAN LOOK UP ON THE SITE OF THE PLATFORM.
# push rtmp://live-ams.twitch.tv/app/LIVESTREAM_KEY;
# push rtmp://a.rtmp.youtube.com/live2/LIVESTREAM_KEY;
# push rtmp://ingest-ams.mixer.com:1935/beam/LIVESTREAM_KEY;
		}
	}
}

EDIT THE DEFAULT SITE CONFIG

nano /etc/nginx/sites-enabled/default

SEARCH FOR THE FOLLOWING LINES:

#location ~ /\.ht {
# deny all;

AND DIRECTLY UNDER IT PASTE THE FOLLOWING

location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root /var/www/html/;
}
#location /control {
# you'll need a htpasswd auth file, that's outside the scope of this doc but any apache one will work
# auth_basic "stream";
# rtmp_control all;
#}

SO THAT IT WILL LOOK SOMETHING LIKE THIS AFTER PASTING:

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}

location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root /var/www/html/;
}
#location /control {
# you'll need a htpasswd auth file, that's outside the scope of this doc but any apache one will work
# auth_basic "stream";
# rtmp_control all;
#}
}

# Virtual Host configuration for example.com
