Installing in a UNC Share

You can install mysql on one server and point both webserver to this mysql installation.

Or you can install mysql on both servers and do a “master-slave” configuration.

Last you can install mysql on both servers and do a “master-master” configuration.

If you have multiple’s mysql, you should consider using hyperdb to configure wordpress access to database

Thanks for the reply, apologies for the delayed response.

MySQL is now installed on both servers, I am now ready to install WordPress properly.

However – whereas MySQL is installed on both servers, WordPress will be installed on the UNC Share, which obviously has a different IP address. This is where I am unsure, what would I specify as the Database Host during installation – localhost, or a specific IP?

Is localhost the IP of the server executing the request, or is it the IP of the current storage location? (I feel like an idiot even asking this!)

Thanks
