Version

When configuring MySQL in your Boxfile, you can define which of the following versions you'd like to use.

• 5.5
• 5.6
• 5.7

Note: Due to version compatibility constraints, MySQL versions cannot be changed after the service is created. To use a different version, you'll have to create a new MySQL service and manually migrate data.

version

# default setting
data.db:
  image: nanobox/mysql
  config:
    version: 5.6

Plugins

This allows you to specify what MySQL plugins to load into your database service. The following plugins are available:

• archive
• blackhole
• federated
• audit_log

plugins

data.db:
  image: nanobox/mysql
  config:
    plugins:
      - federated

Note: When using the audit_log plugin, you must also specify a audit_log setting in your Boxfile.

Event Scheduler

This enables or disables MySQL's event scheduler.

Note: Even though event_scheduler's default is "Off", it can still be enabled through a SQL query in your database. Setting it to "On" just enables the event scheduler when the database is provisioned.

## Custom user config 2
data.db:
