to load mysql with a config file, is a switch needed or will it look for the config automatically?

also, is there a way to tell mysql to write an output file to a dir other than /usr/mysql/data/db_name? i need to set up a config to allow a client to output to file in a dir that is accessible by apache for download, but i cannot see how to make it happen.

thanks

n/m on this, worked around this by using the /tmp and pulling from there.

MySQL should find /etc/my.cnf automatically if it exists.

You can change the database location in /etc/my.cnf (I don't know the details, but I think it has to be server-wide) but putting it where it can be downloaded by apache? Wouldn't you be better off letting apache follow a link?
