7# Installation Instructions
8# ----------------------------------------------------------------------
9#
10# On Linux you can copy this file to /etc/my.cnf to set global options,
11# mysql-data-dir/my.cnf to set server-specific options
12# (@localstatedir@ for this installation) or to
13# ~/.my.cnf to set user-specific options.
14#
15# On Windows you should keep this file in the installation directory 
16# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
17# make sure the server reads the config file use the startup option 
18# "--defaults-file". 
19#
20# To run the server from the command line, execute this in a 
21# command line shell, e.g.
22# mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
23#
24# To install the server as a Windows service manually, execute this in a 
25# command line shell, e.g.
26# mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
27#
28# And then execute this in a command line shell to start the server, e.g.
29# net start MySQLXY
30#
31#
32# Guidelines for editing this file
33# ----------------------------------------------------------------------
34#
35# In this file, you can use all long options that the program supports.
36# If you want to know the options a program supports, start the program
37# with the "--help" option.
38#
39# More detailed information about the individual options can also be
40# found in the manual.
