You could setup a local DNS service, and make users use a hostname (in normal cases pointing to the master) to access your service.
In case of failure, you simply change the DNS record of that hostname to point to the slave machine.
Users wouldn’t notice the change if you change the IP that hostname resolves to.

Thats Genius ! , Although i’ll have to change the way the users connects to the database in order to make a seamless transition in the event of a failure.

Dear Robert,
What about running multiple MySQL services on the slave host? Each would be running on a different port and would be dependent on a different master.

Great, just what i needed. Now … Is it possible to set several Master devices to replicate in just one Slave Server ?. I’m asking this because im trying to set up an Active-Stanby topology in which, if one of the Masters Fails it could be replace temporarily by the Slave server. Thanks
