Editing Hosting A PHP Web Application On AWS (section)

==== Database ====

Either select an existing snapshot, or create a new database. 

For example, MariaDB is not available from the list of database types when creating a new database. In order to link the EBS to a MariaDB database, first create the MariaDB instance in the AWS RDS Management Console. Then create a snapshot of the database. Then select that snapshot when selecting a database for the EBS.

Security group rules must be configured to allow the EB instance to make connections to the RDS database. 

* '''AWS Management Console''' > '''RDS''' > '''Instances''' > ''my instance'' > click for details
* Scroll down to the '''Connect''' pane to view a list of '''Security groups'''
* An inbound rule needs to exist for the VPC that was created for the EB instance.
* Scroll farther down on the RDS instance details page for the '''Details''' pane > '''Security and network''' > '''VPC''' > click on the VPC name to view its details, e.g. its IPv4 CIDR.
* Click on a '''CIDR/IP - Inbound''' security group to edit its settings.
* '''Security Groups listings''' page > Click on the row for the RDS's security group > '''Inbound''' tab > '''Edit''' button
** '''Type:''' e.g. MYSQL/Aurora, or appropriate database type
