Caution the mysql driver has known timeout issues. See #257.

MySQL

Drone comes with support for MySQL as an alternate database engine. To enable MySQL, you should specify the following environment variables:

DATABASE_DRIVER="mysql"
DATABASE_CONFIG="root:pa55word@tcp(localhost:3306)/drone"

MySQL configuration

The following is the standard URI connection scheme:

[username[:password]@][protocol[(address)]]/dbname[?options]

The components of this string are:

• username optional. Use this username when connecting to the MySQL instance.
• password optional. Use this password when connecting to the MySQL instance.
• protocol server protocol to connect with.
• address server address to connect to.
• dbname name of the database to connect to
• ?options connection specific options

This is an example connection string:

root:pa55word@tcp(localhost:3306)/drone

MySQL options

See the official driver documentation for a full list of driver options.

MySQL Database

Drone does not automatically create the database. You should use the command line utility or your preferred management console to create the database:

mysql -P 3306 --protocol=tcp -u root -e 'create database if not exists drone;'
