=head1 mysqlsetup
This is script is called after the installation or upgrade of MySQL
on xCAT. It will automate the setup of the MySQL and xCAT to run
xCAT on the MySQL DB.
Note: if will setup an xcatdb,a xcatadmin, and a MySQL root password.
It will interact for the
password to assign, unless the XCATMYSQLADMIN_PW and the XCATMYSQLROOT_PW
env variables are set to the admin and mysql root password, resp.
Setups up AIX and Linux, but most work needs to be done on AIX.
See man mysqlsetup for more information and the xCAT2.SetupMySQL.pdf
documentation.
