Make a shell script in /etc/cron.daily that does this:
mysql -u youruser --password=yourpassword -h yourdatabase server -e
'DELETE FROM session_mysql WHERE (last_accessed + INTERVAL 7 DAY) < NOW()'
(disclaimer, haven't tested the script, we have a perl script that's way
more complicated than this, but thats the query we run)
7 days is a long time but allows for some debugging of old sessions.
Otherwise 1 day is plenty (it only has to be greater than the expiretime
on your sessions)
Another note: Either use myisam as the table type, or if using innodb
turn off the primary key on code (make it a unique index instead).
Innodb is very slow when using random primary keys (which I found out
the hard way over the christmas rush :-/ )
