#
|
||
# Installation Instructions
|
||
# ----------------------------------------------------------------------
|
||
#
|
||
# On Linux you can copy this file to /etc/my.cnf to set global options,
|
||
# mysql-data-dir/my.cnf to set server-specific options
|
||
# (@localstatedir@ for this installation) or to
|
||
# ~/.my.cnf to set user-specific options.
|
||
#
|
||
# On Windows you should keep this file in the installation directory
|
||
# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
|
||
# make sure the server reads the config file use the startup option
|
||
# "--defaults-file".
|
||
#
|
||
# To run the server from the command line, execute this in a
|
||
# command line shell, e.g.
|
||
# mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
|
||
#
|
||
# To install the server as a Windows service manually, execute this in a
|
||
# command line shell, e.g.
|
||
# mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
|
||
#
|
||
# And then execute this in a command line shell to start the server, e.g.
|
||
# net start MySQLXY
|
||
#
|
||
#
|
||
# Guidelines for editing this file
|
||
# ----------------------------------------------------------------------
|
||
#
|
||
# In this file, you can use all long options that the program supports.
|
||
# If you want to know the options a program supports, start the program
|
||
# with the "--help" option.
|
||
#
|
||
# More detailed information about the individual options can also be
|
||
# found in the manual.
