I have spend the last couple of days trying to find out a solution for migrating changes from a development database to the productive. I was looking for a clean, simple and reliable solution that (ideally) runs on Linux.
My first attempt was to to use the official MySQL
mysqldiff command. It turned out that in my case, the only suggestion I got was to recreate indexes and drop primary keys every time there was a record number mismatch between tables. I also run into Windows GUI's with a 30 day evaluation period and a cost ranging from $90-$150.
My lack changes when I run into Schema Sync written in Python by Mitch Matuson. The page has everything you need and the setup (if you already have python) takes less that a minute.
Quoting from the utility's examples page,
Sync the production db with the changes from the development db
schemasync mysql://user:pass@dev-host:3306/dev_db mysql://user:pass@prod-host:3306/production_db
This will give you two files in your home directory, one to do the patching and one to revert back the changes if requested. A excellent piece of work, that I am very happy to use. Thumbs up for mr Matuson.
