In order to use the Dolphin 7 RMS feature the service must either be available from your host, or you can use a 3rd party RMS stand alone provider in conjunction with whoever you host with. If you have a VPS or Dedicated Server with root access and privileges you can install your own RMS media server. You can't install RMS on standard shared hosting.
After you install Dolphin 7, you will need to turn on RMS in your administration if you intend to use it assuming your host provides RMS or you are using a 3rd party. In order to turn it on and enable it first login to your Dolphin 7 administration.
Find and navigate to:
Then, find and click on the "Settings" icon link on the right side of the screen.
A window will open or appear where you can enter the details that your host or RMS provider must give you. It looks like this:
To turn on and enable RMS you must tick or check the box "Use RMS"
The RMS Address will be an ip address that your provider gives you
The default RMS Port is 1935
The default HTTP Port is 5080
And you are done.
Unless your provider has changed the RMS and HTTP Ports the only thing you generally need to enter is an ip address and check the box that says enable RMS.
It would look something like this:
There are a few hosts and providers that occasionally use different RMS and HTTP Ports. If they do just enter what they tell you and save the changes.
There really isn't much to enabling RMS in Dolphin 7 Administration.
Installing RMS on your own VPS or Dedicated Server isn't too difficult if you have server administration experience. If you don't know that much about servers and administration it can be a bit on the confusing side. You can also find and pay someone to install it for you if you have a VPS or Dedicated server.
Check out the list of Dolphin Hosting providers. Some include RMS and others do not.
