Sub Domain with different ports in Plesk

Question

I am new to Plesk ( and virtual servers in general ). I have a server running CentOS and Plesk 12 and my domain and web site are working perfectly. At present I also have an instance of Dreamfactory running on port 82 (so access it at http://example.com:81 ) but I wondered if it were possible to setup a subdomain with plesk such as http://api.example.com that would load my dream factory instance without forwarding to http://example.com:81 (effectively masking the port number).

Answer 1

Open sub-domain's "Apache & nginx Settings" and add into "Additional directives for HTTP":

# for Apache
ProxyPass / http://example.com:81/

Or

# for Nginx
location ~ / {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_pass http://example.com:81;
}

Like this for Apache:

Or like this for nginx:
