suggestion needed about du command run on PHP

["Mark Lo (3)" <mark 3dsources com>]

Hi,

     I would like to run a du command to find out how many bytes of each
databases is consuming under PHP+ Apache.  But, the problem is I am not able
to count the bytes of the databases in MySQL, because the user and group is
set to MySQL.  On the other hand, My Web server is running on user nobody
and group nobody.  So, What suggestion will you give me in order to count
the bytes of each database is consuming using apache + PHP.

Should I change the apache's user and group to mysql or Should I make the
mysql database world readable.

Any Suggestions is helpful.


Thanks in Advance

Mark
