5. Prepare RDS MySQL Database
NOTE: For Optimal performance, the Stream Manager and Database should be in the same Region
- Open the AWS RDS console
First - create a new
parameter groupso that you can define a higher maximum connection count:
- From the left-hand navigation, choose Parameter Groups
- Click on Create parameter group
- Parameter group family: mysql8.0
- Set a group name (something you'll remember - like red5proautodb), then click on create
- Select your new group from the list, then click on the Parameter group actions pull-down, and select Edit
- Using the filter, search for
- Change the value from
100000(the highest allowed)
- Save changes
- From the left-hand navigation, under RDS Dashboard, click on Instances
- Click on Launch DB Instance
- Step 1: Select Engine - Click on the MySQL tab and click Select
- Step 2: Production? - Select MySQL for production environment use and click the “Next Step” button.
- Step 3: Specify DB Details - Set the DB Instance Class as per your traffic needs, keeping in mind that higher configurations account for higher billing charges by AWS. For Storage Type, anything other than magnetic helps in a performance boost. Stream Manager doesn't require much storage, but depending on your use case you may want to allocate more or less space accordingly. The default settings will likely be sufficient for your autoscaling solution. For DB Engine Version, choose 8.0.
- Finally set a database instance identifier and database credentials for access by the Stream Manager. Make a note of the username and password.
- Step 4: Configure Advanced Settings -
- VPC - select the VPC that you created for autoscaling
- Subnet Group: Create a new DB Subnet Group (or use default)
- Publicly Accessible: Yes
- Availability Zone: No Preference
- VPC Security Group(s): Create a new Security Group (We will be configuring the security group for RDS next)
- Database Name: cluster
- DB parameter group: choose the parameter group that you created above
- Leave other options as their default values.
- Backup, Monitoring, and Maintenance options should be configured per your operations' requirements.
- Click Launch DB Instance
- Click on the View your DB Instances.
- You should now be able to see your DB instance being created. It will take several minutes (you can stretch your legs now) for the initialization process to be completed.
- When Status has changed from "creating" to "available" select your database instance and click on the configuration details tab icon (middle icon).
- Make a note of the Endpoint URL (will be something like streammanager-db.abcdefghijk123.us-west-1.rds.amazonaws.com) of the MySQL database since this will be used for the config.dbHost variable in the stream manager red5-web.properties file.
- On this tab, locate and click on the Security Group for this instance to navigate to the security group configuration page.
- Select the security group (Description will be "Created from the RDS Management Console") and click on “Actions” => “Edit inbound rules” option.
- Click Add Rule
- Select - “MySql/Aurora” for Type (port 3306)
- Select - “Custom IP” in the source and enter the stream manager's elastic IP address with its CIDR. (typing a “ / ” after the IP address will auto-suggest CIDR values for you to select)
- Additionally, you will need to add the private IP address of the Stream Manager to the security group - this will be assigned after the Stream Manager instance is associated with the reserved IP address. Alternatively, you can add the stream manager security group id.
- Alternatively, if you choose "custom" you can also enter the security group ID (
sg-#####) used by your stream manager (or load-balanced stream managers)
- For source, select “My IP” to add your IP address to the whitelist of the RDS security group. This will ensure that you can connect to MySql from your desktop and populate the database schema using an RDS client. When you select My IP in source amazon will auto-fill in your CIDR too. (note: AWS may have already added this by default)
- Click “Save” to apply changes to this security group. Your stream manager instance will now be able to connect to the MySQL instance after it has been deployed.
