NOTE: The following steps need to be done for each server instance to be used as Red5 Pro nodes (origins and edges).
NOTE #2: We recommend a minimum of 2 CPUs and 4GB RAM for Red5 Pro node servers.

Install Red5Pro on the Instance

• Follow the Installing Red5Pro on a Linux Server instructions
• Make sure that Red5 Pro service is set to auto-start on launch
• Connect to your instance using the private key from the key pair that you created
• ssh -i ~/.ssh/keys/red5prokey ubuntu@<server_ip_address>
• Red5 Pro Clustering does not work without a license. You will need to purchase a Red5 Pro Professional license from https://account.red5.net. 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)

If you haven’t already, Install NTP (network time protocol). NTP is necessary to ensure that the Stream Manager and all nodes are in sync. sudo apt-get install ntp The service should start automatically once installed.

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 a unique value. Make a note of this password, to be used in the Stream Manager red5.properties file.

Enable Red5 Pro Server API and Set Management Password

Configure the Server API per this document. Modify the security.accessToken value in {red5pro}/webapps/api/WEB-INF/red5-web.properties, and make a note of it. You will need this value for your Stream Manager.

### CORE SECURITY PROVIDER SETTINGS
security.hostSecurity=true
security.tokenSecurity=true
security.accessToken=

Add the Stream Manager’s public IP address to the {red5pro}/webapps/api/WEB-INF/security/hosts.txt file (or add * to make the API accessible from anywhere).

localhost
*

Remove Unnecessary Webapps

To ensure a faster startup time for your server, we suggest deleting any webapps that you will not be using from the {red5pro}/webapps directory (for example: template, streammanager; do not remove root). For ease of setup for the Stream Manager, leave a zipped copy of the server distribution on the server.

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

The following incoming ports need to be open on the Red5 Pro node servers

Verifying Red5 Pro on Instance

Start Red5 Pro service

sudo 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.

The Red5 Pro service must be running on the nodes in order for the Stream Manager to provision them/
