VPS cheap multistream setup

With this practical guide, you will create a server that forward the received stream to services like YouTube ad Facebook, as a self-hosted alternatives to services like Restream.
If you want to dive deeper on a multistream setup, look at the article on my blog.

Initial server setup

Follow the guide at Initial VPS setup

Install required packages

Install nginx:
```
$ apt-get install nginx
```
Install the RTMP module:
```
$ apt-get install libnginx-mod-rtmp
```
Update the firewall and check if the setup is OK:
```
$ ufw allow 1935
$ ufw status verbose
```
Reboot

Setup NGINX

Edit NGINX config:
```
$ nano /etc/nginx/nginx.conf
```
At the end of the file add the following:

rtmp {
	server {
		listen 1935;
		chunk_size 4096;

		application live {
			live on;
			record off;
			
			push rtmp://a.rtmp.youtube.com/live2/<your-youtube-key>;
			push rtmp://127.0.0.1:19350/rtmp/<your-fb-persisten-key>;
		}
	}
}

Restart NGINX
```
$ systemctl restart nginx
```

(Only if you use Facebook) Setup Stunnel

Install Stunnell:
```
$ apt-get install stunnel4
```
Enable Stunell auto boot:
```
$ nano /etc/default/stunnel4
```
Change ENABLE to 1:
```
ENABLE=1
```
Edit Stunnel configuration:
```
$ nano /etc/stunnel/stunnel.conf
```
Enter the following config:

pid = /var/run/stunnel4/stunnel.pid
output = /var/log/stunnel4/stunnel.log

setuid = stunnel4
setgid = stunnel4

# https://www.stunnel.org/faq.html
#socket = r:TCP_NODELAY=1
#socket = l:TCP_NODELAY=1

debug = 4

[fb-live]
client = yes
accept = 127.0.0.1:19350
connect = live-api-s.facebook.com:443
verifyChain = no

Enable Stunell on boot:
```
$ systemctl enable stunnel4.service
```
Restart Stunnell
```
$ systemctl restart stunnel4.service
```

Ready to test!

Test setup with OBS.

OBS Stream configuration

Go to Settings»Stream

Service: Custom Server: rtmp://<ngnix server IP address>/live Stream Key: test

Setup scripts

I have created some scripts to execute the setup automatically. You can find them here with all the instructions. I suggest you to execute the setup manually the first time, to understand better what is going on.
