How to redirect a subdomain to the main server address along with a port?
I want to redirect subdomain.domain.tld to my IPaddress:port . The domain.tld is already pointed to the server IP address. Can I do it just by adding an srv record? I am using apache2 and ubuntu. Do I need to redirect, use virtual host ? Since I am a newbie would be really thankful to the precise process. If thats too much to ask can someone point me to the relevant information page.
Thanks in advance
Redirecting a subdomain to a specific port on the your main server can be done by creating an SRV record in addition to your A record, but there is also a method that can be performed using a Virtual Host file.
The SRV record will define the transport protocol, port number, priority, and target for a specific service running on your domain.
You can use the Linode DNS Manager to set up your SRV record.
Service: _service. Protocol: tcp Priority: 10 Weight: 30 Port: 5060 Target: .example.com TTL: Default
Depending upon your desired port and priority, you SRV record will resemble something like this:
_service._tcp.example.com SRV 10 30 5060 service.example.com
For more information on how to set up an SRV record, you can review the SRV section of Linode's DNS Records Guide Page.
Virtual Host File
It is also possible for you to redirect your subdomain to a specific port on the server using a Virtual Host file. Similar to the SRV record method, you'll need to specify the service, target, and port number in the VH file:
<VirtualHost *:80> ServerAdmin [email protected] ServerName subdomain.example.com ServerAlias subdomain.example.com ProxyRequests Off #ProxyPass / http://localhost:8080/ <Location /> ProxyPreserveHost On ProxyPass http://example.com:8080/ ProxyPassReverse http://example.com:8080/ </Location> # Uncomment the line below if your site uses SSL. #SSLProxyEngine On </VirtualHost>
For more information on how to configure a Virtual Host file for subdomain redirects, I'd recommend checking out this Q&A site Subdomain to Port redirect. Good luck!
