vps - How to configure nginx for multiple site applications under one domain name?

Question

Like this
www.example.com
blog.example.com
But different applications, for example www.example.com is a static page, and blog.example.com is a nodejs application
Can it be done? How to configure it specifically?

Answer 1

Configure root for the static page and configure the reverse proxy for the application

server {
    listen      80;
    server_name blog.example.com ;    
    
    location  / {    
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-Ip $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect off;
    }
}

server {
    listen      80;
    server_name www.example.com;
    
    location  / {
        root E:/Example/public;        
     }
}

Answer 2

Configure the virtual host
Post the pseudo code for reference

Add at the end of the server section of the configuration file nginx.conf

include vhost/*.conf;

Create the vhost directory
Create files in the vhost directory, such as www.example.com.conf, blog.example.com.conf
Then make the following configuration

server
{
    listen 80;
    server_name www.example.com;
    index index.php index.html index.htm ;
    root /var/www/www.example.com;
    
    if ( $fastcgi_script_name ~ \..*\/.*php ) {
        return 403;
    }
    
    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Of course, nodejs does not rely on ng. ng specifies the nodejs application folder. Domain name access only triggers initialization, and other communication and explanations are returned to the node service
