Replicate data from one MySQL DB to another

Hi,

I have two servers, hosted by different companies.  Both running MySQL.  I was wondering if there's a script that could run automatically that would transfer all of the data in the DB from one server over to the other.  Preferable something that ran automatically, like every 4 hours.  The table structure would be the same on both servers.

Thanks

It depends on how you need to handle your data. What is the purpose of this scenario?
Usually one would go for a binary log and apply it to the second server (master/slave setup).

Do you have direct access to the mysql servers?
I.e. you would have an application/script running locally that will connect to each mysql server and perform the select/if exists update else insert into the other.
You can configure the frequency within your local system as well as add the logic to speedup the process by not retrieving unchanged data unnecessarily.

Both servers are on shared hosting plans, so  I don't know if I have the kind of access you're talking about.  I was hoping there would be a msysql script that could auto-run.

In the scenario you describe, you can not without using an external process i.e. on your local computer you setup a script that will access a special PHP page on one host to get the data and then use a special php on the other host into which you will insert the data.

I'd think most hosting firms include access to phpmyadmin that has the ability to export backup the datatabase.  Using phpmyadmin you can then import/restore the database on the other host.

You could as part of access to your php page trigger checks to the other to perform replicative tasks.
i.e. a php request is received. and a response is provided instead of the PHP exiting, it will query the remote site and further process data.  note that this will increase the load on your system.  Note futher, that your hosts may prevent outgoing requests from the web servers which is what is needed from one to be able to access the other.
