When installing the .rpm, a message is printed describing how to use another mysql server. The message is:
To use a remote MySQL server and disable the local MySQL server,
add the connection information to this file:
The default contents of my.cnf.setup are:
user = root
host = localhost
port = 4406
Update the contents of my.cnf.setup with your MySQL server information.
If you set a password in my.cnf.setup, then the install script assumes an already configured MySQL server is available, and uses the values in my.cnf.setup. Additionally, the built-in MySQL server is disabled.
