A MySQL database stores information about subjects, studies, and analyses. The database needs to be set up either on a local computer, or on a server. This page contains installation and upgrade directions, and subpages below explain other actions.
Install MySQL
Search for mysql community server, and download and run the installer. Choose a custom setup, and select the 64-bit MySQL server, the workbench, and the Connector/J.
2014-10-02: Australia: The installer crashes when the date format is not US (for details see down page). To run the installer, go to Control Panel, Region, and under formateselect on one computer, so I downloaded the installation files directly.
Upgrading from previous version
Sometimes prior versions can cause problems. It is best to export the database, uninstall the MySQL server and other components, and restart so the services are removed. Make a note of any MySQL users (other than root), as you may want to re-create these to ensure consistency.
If you have trouble upgrading (there is one step where an old password is requested, which can be difficult to figure out), you should delete the MySQL data, which is the MySQL folder under C:\ProgramData\ in Windows 7. The fodler is hidden, so you need to type it into the address line of Explorer.
If you upgraded without uninstalling, and had problems
You may need to delete services
Command Prompt, Run As Administrator, sc delete "service name".
If the service status is "Starting" then you need to kill the process.
Command Prompt, Run As Administrator, sc ??? "service name" to get PID; then taskkill /F /PID <the PID>
Crashing win Australia
When you select the product ("MySQL Server 5..21 below), the installer crashes with something about a strong and datetime error.
Go to Region as below (Control Panel); change the Location to United States, then the Format to English (United States). Click Apply to keep the Window open, so you can easily change it back when done.
