Optional - Load Balance Stream Managers

Optional - Load Balance Multiple DO Stream Managers


  • Create the first Stream Manager per the above instructions, then create an image from that instance. Build subsequent stream managers from that image. It is essential that the config files be identical between the two stream managers with one exception:
  • Edit red5pro/webapps/streammanager/WEB-INF/red5-web.properties and modify ## LOADBALANCING CONFIGURATION streammanager.ip=, adding the Assigned IP address of the individual Stream Manager instance you are modifying.
  • IMPORTANT make sure to give any stream manager instances access to the PostGres database before you start the Red5 Pro service on them. Then you can add them to the load balancer.

Add Wildcard Certificate

If you can download a wildcard certificate from your DNS provider, then that is recommended. If you can't, then you can generate one through Let's Encrypt as long as you have access to your DNS management, as it requires adding a TXT record.

  • Navigate to Account, Settings, Security tab.
  • Under Certificates click on Add Certificate
  • If you are hosting your domain on Digital Ocean, you can "Search for a domain on Digital Ocean", otherwise, click on the "Bring your own certificate" tab. You will need the cert.pem, privkey.pem, and chain.pem files from Let's Encrypt.
  • Name the SSL certificate (for example *.mydomain.com)
  • In the Certificate field, copy & paste the full text from the cert.pem
  • In the Private key field, copy & paste the full text from the privkey.pem
  • In the Certificate chain field, copy & paste the full text from the chain.pem
  • Save the certificate to use below
