I have a default Laravel application running on port 80. It use PHP 7 default setup. Now I want to add another nodejs apps which usually running on port 3000 and use reverse proxy on Nginx from port 8000 to 3000. But it turn out to be 502 bad gateway. Here is my pm2 status

┌──────────┬────┬─────────┬──────┬───────┬────────┬─────────┬────────┬─────┬───────────┬──────┬──────────┐
│ App name │ id │ version │ mode │ pid │ status │ restart │ uptime │ cpu │ mem │ user │ watching │
├──────────┼────┼─────────┼──────┼───────┼────────┼─────────┼────────┼─────┼───────────┼──────┼──────────┤
│ FAM │ 0 │ 1.0.0 │ fork │ 16073 │ online │ 0 │ 97m │ 0% │ 48.4 MB │ root │ disabled │
└──────────┴────┴─────────┴──────┴───────┴────────┴─────────┴────────┴─────┴───────────┴──────┴──────────┘
 Use `pm2 show <id|name>` to get more details about an app

I suspect the real reason of 502 is because the user is root so I change all my js files ownership to

I have expose the 8000 port on firewall-cmd as well add it to /etc/service. But it all failed.

Here is the nginx default conf (/etc/nginx/nginx.conf)

For your information, this VPS has no domain name set yet. So it all run on regular http.

And here is conf for 8000 port

upstream fam-app 
 server <VPS_IP>:3000;


server 
 listen 8000;
 location / 
 proxy_set_header X-NginX-Proxy true;
 proxy_pass http://fam-app/;
 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_set_header X-Real-IP $remote_addr;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_redirect off;
 proxy_max_temp_file_size 0;
 proxy_read_timeout 240s;

 

Most solution shows how to run pm2 and nginx on Ubuntu but not much about Centos 7. What do you think?
