I’m building RTC video call with janus gateway through websockets.
Need some suggestion about how to proxy pass 3 server.
I don’t know if port forwarding is the correct name for this case
I have 3 server: A -> B -> C
Janus gateway installed on server C on port 8080
then I configure Nginx on server B to proxy pass that C:8080
like this
location /janus {
proxy_pass http://C:8080;
}
then on server A the configure should be like this:
location /janus {
proxy_pass http://B/janus;
}
Then I can access C:8080 with this url: http://A/janus
It works.
Can I use same approach to run websocket through proxy pass?
the configure should be like this on server B:
map $http_upgrade $connection_upgrade{
default upgrade;
'' close;
}
upstream Cwebsocket{
server C:8188;
}
server {
listen 443 ssl default_server;
listen [::]:443 ssl default_server;
location /Bwebsocket{
proxy_pass https://Cwebsocket;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
}
Then I configure this on server A:
server {
listen 443 ssl default_server;
listen [::]:443 ssl default_server;
location /Awebsocket{
proxy_pass http://B/Bwebsocket;
}
}
Is it the correct way to proxy_pass between servers specially for websocket?
Or I have to use different approach with this case? CMIIW
Actually its not efficient to use 3 server but this topology kinda policy on my place.
Need help guys
Thanks in advance 🙂
