Otherwise it's an efficient way to split your system resources in half. The OP could look at /etc/init.d/mysqlmanager which seems to support the idea of instances, but I'm not sure it would be useful outside running the same binary on a different port. > Isn't MySQL slotted, so you can run different major versions (4 and 5, > for example) at the same time? > Not slotted in any meaningful within the system. You have to chroot. There was an attempt to do it within Gentoo a few years back, but it overly complicated for the average user and poorly implemented. kashani -- gentoo-user@lists.gentoo.org mailing list
