Re: Need To Get "Localhost" Back.
To have two versions of MySQL server on your machine, they'll need to have separate /data folders, separate my.ini files, and run on different ports if you want to run them at the same time.
Did you install 5.6 as a service? If so,
start
Run
services.msc
Look for mysql service(s). Find the 5.6 service. Right click, Properties
The Path to executable will have -defaults-file=path\to\my.ini_file on the end of it.
V5.6 defaults to puttting the my.ini file in c:\ProgramData\MySQL\MySQL Server 5.6\ folder
If MySQL 5.6 is not a service, when you start the server with a command line, you'll need to provide the -defaults-file= option to tell MySQL where to find your my.ini file.
Good luck,
Barry.
