MySQL Replication Between Major versions
Posted on 2009-07-01
I have a rather interesting problem (or at least it is interesting to me). I have a MySQL 4.1 server I am restricted to that version because it is required by our POS (point of sales) software. See i want to utilize triggers to aid in some integration with our website and email marketing company. Though the fact that triggers aren't available unless your using version 5.0 or newer sort of hurts things.
Now that's what I'm wanting to do and here is what i've tired:
I figured for giggles i would just setup a master/slave replication between 4.1 and 5.0. Unfortunately the servers weren't replicating. I can only assume that they were because of a skip-name-resolve defined in the 4.1 server config file. Now the reason that is there is because the server was throwing a fit by the fact there is second network attach to the machine with no gateway it's just a cross over cable between it's self and it's network based raid 1 server for fail over.
So at this point i'm at a loss. on how i can achieve my end result. There are things i need to do instantly when a row is updated/inserted into certain tables with in our POS database. Anyone have ideas?
