How to set up URL forwarding in nginx ubuntu?

Current env is ubuntu server 20, nginx installed.

port info is stored in a csv file , like

c1234=8081
c5678=8082

is it possible to use grep to get that port ?

What keyword I should search? Proxy or forwarding or rewrite? Any web link is welcomed.

Thank You

Solution

Nginx Reverse Proxy would help with this.

This setup allows you to redirect incoming requests from Nginx to backend servers based on the path.

location ~ ^/c1234(.*)$ {
    proxy_pass http://127.0.0.1:8081/web$1;
}

location ~ ^/c5678(.*)$ {
    proxy_pass http://127.0.0.1:8082/web$1;
}

The ~ ^/c1234(.*)$ is a regular expression matching the path that starts with /c1234
proxy_pass is the directive to redirect the traffic.
Just change the 127.0.0.1 IP address to the needed IP address.

Test the configuration and reload NGINX

sudo nginx -t
sudo systemctl reload nginx

You should be able to achieve

http://192.168.1.5/c1234 --> http://192.168.1.5:8081/web

http://192.168.1.5/c5678 --> http://192.168.1.5:8082/web
