Set up a local MySQL database for use with heat.
This script will create a 'heat' database that is accessible
only on localhost by user 'heat' with password 'heat'.
Usage: heat-db-setup <rpm|deb> [options]
Options:
select a distro type (rpm or debian)
--help | -h
Print usage information.
--password <pw> | -p <pw>
Specify the password for the 'heat' MySQL user that will
use to connect to the 'heat' MySQL database. By default,
the password 'heat' will be used.
--rootpw <pw> | -r <pw>
Specify the root MySQL password. If the script installs
the MySQL server, it will set the root password to this value
instead of prompting for a password. If the MySQL server is
already installed, this password will be used to connect to the
database instead of having to prompt for it.
--yes | -y
In cases where the script would normally ask for confirmation
before doing something, such as installing mysql-server,
just assume yes. This is useful if you want to run the script
non-interactively.
