Prepare Red5 Pro Node Instance

Linode Instance for Node Image

  • Click on Create and select Linode from the Linodes section.
  • Choose Image – red5-optimized-disk-image (Optimized Linode Image)
  • Select Region from the drop-down list.
  • Use dedicated CPU 8GB Plan (You can also use 4 GB depending upon your load)
  • Provide a Linode Label as per your choice For Example – red5pro-autoscaling-sm-nodes
  • Add tags, For Example – node-image.
  • Enter a Strong root password and select the SSH key added in the previous step.
  • Click on Create Linode.

Install Red5 Pro on the Instance

  • Connect to your instance over ssh as the root account.
  • Follow the Installing Red5Pro on a Linux Server instructions.
  • Make sure that Red5 Pro service is set to auto-start on launch.
  • Red5 Pro Clustering does not work without a license. You will need to purchase a Red5 Pro Professional license from Red5 Pro. Add a file named LICENSE.KEY with your Pro license key (16 characters, plus dashes, like: YOUR-LIC-ENSE-KEY1) to the root of the Red5 Pro Server installation ({red5prohome}/LICENSE.KEY).

Configure Autoscaling on the Instance

Navigate to the location where you extracted the red5pro files, and edit the file {red5prohome}/conf/autoscale.xml

  • Change the active value from “false” to “true”
  • Replace http://0.0.0.0:5080 with https://your-streammanager-url
  • Save and close the file

example:

    <bean name="config" class="com.red5pro.clustering.autoscale.Configuration" >
        <property name="active" value="true"/>

        <!--Stream manager hosted uri. use the host of your stream manager.  -->
                <property name="cloudWatchHost" value="https://red5autoscale.red5pro.com/streammanager/cloudwatch"/>

Set a Unique Cluster Password

Edit the file {red5prohome}/conf/cluster.xml and replace the default <!-- edge/origin link cluster password --> password from changeme to sometime unique. Make a note of this password, to be used in the Stream Manager red5.properties file.

Remove Unnecessary Webapps and Plugins

To ensure a faster startup time for your server, we suggest deleting any webapps that you will not be using from the {red5prohome}/webapps directory (for example: secondscreen, template, vod, streammanager). For ease of setup for the Stream Manager, leave a zipped copy of the server distribution on the server. If you are running a custom webapp, then you would want to include that on your node servers.

In addition, it is recommended that you remove any plugins (found in the red5pro/plugins directory) which you will not be using, from the following list:

  • red5pro-mpegts* -- HLS
  • red5pro-restreamer* -- restreamer
  • red5pro-socialpusher* -- social media restreaming

Verifying Red5 Pro on Instance

Start Red5 Pro service

systemctl start red5pro

Once you have started the Red5 Pro Server, you can verify that it is running and available by opening a web browser and navigating to http://<server-ip>:5080, where is the Public address value of your Red5 Pro server.
