How to load website on port 80 with nginx?

Question

Nginx

I upload the site to the vps server, use pm2 to launch the site, domain_name:3334 will open, how to make it open just by the domain name, tell me the algorithm of actions please. Tried to edit /etc/nginx/conf.d/domain_name.conf folder, add proxy_pass. Did not work out.

Answer 1

server {
    listen 80;
    server_name site.example.ru;
     location / {
        proxy_pass http://127.0.0.1:3334/;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;


        proxy_buffer_size          128k;
    	proxy_buffers              4 256k;
    	proxy_busy_buffers_size    256k;
    }

}
