5.12.1. Running Multiple Servers on Windows
You can run multiple servers on Windows by starting them
manually from the command line, each with appropriate operating
parameters. On Windows NT-based systems, you also have the
option of installing several servers as Windows services and
running them that way. General instructions for running MySQL
servers from the command line or as services are given in
Section 2.3, “Installing MySQL on Windows”. This section describes
how to make sure that you start each server with different
values for those startup options that must be unique per server,
such as the data directory. These options are described in
Section 5.12, “Running Multiple MySQL Servers on the Same Machine”.
