Re: Multiple Server on one Windows machine

[Barry Galbraith]

MySQL installer will only install one instance on Windows.
You need to install the second instance manually.
You don't need a 2nd copy of the binaries, only a second my.ini file, a second datadir (specified in the 2nd my.ini) and install the 2nd mysql service from Windows commandline.

https://dev.mysql.com/doc/refman/8.0/en/windows-start-service.html

The commandline will include the name of the 2nd service, and the name of the 2nd my.ini file. The 2nd my.ini file will have the port and datadir details for the 2nd instance.

Good luck,
Barry.
