Deploying multiple Go applications using Nginx

Question

The are two web applications (websites) written on Go. One is turalasgar.pro (here I am using Go built-in server). Another is engossip.com (for now it displays the same ip as former). I have a vps. I know I should use Nginx, but have no idea how? I have heard of Caddy. Please, I need only nginx server, not Caddy. What I need is run two (or more) applications by using my same vps. How should I configure Nginx configuration? Whether by listening to different ports or to the same port. Practical advices and examples highly appreciated.

Answer 1

It's called reverse proxy. Each application uses it's own port to listen. And then you just point to them in nginx config:

server {
    listen 80;
    server_name turalasgar.pro;
    location / {
        proxy_pass http://localhost:8080;
        ...
    }
}

server {
    listen 80;
    server_name engossip.com;
    location / {
        proxy_pass http://localhost:8081;
        ...
    }
}

Answer 2

Well is really easy.

follow this guide:

After you achieved one application working with martini+nginx just add another server block for the other app.

In case you need more information about server blocks:

Answer 3

Above solutions I tried but didn't work for me

https://gist.github.com/soheilhy/8b94347ff8336d971ad0

server {
listen       ...;
...
location / {
    proxy_pass http://127.0.0.1:8080;
}

location /blog {
    rewrite ^/blog(.*) /$1 break;
    proxy_pass http://127.0.0.1:8181;
}

location /mail {
    rewrite ^/mail(.*) /$1 break;
    proxy_pass http://127.0.0.1:8282;
}
...
