# When this is done the mysql server will be started when the machine is

# If you install MySQL on some other places than @prefix@, then you
|
|
# have to do one of the following things for this script to work:
|
|
#
|
|
# - Run this script from within the MySQL installation directory
|
|
# - Create a /etc/my.cnf file with the following information:
|
|
# [mysqld]
|
|
# basedir=<path-to-mysql-installation-directory>
|
|
# - Add the above to any other configuration file (for example ~/.my.ini)
|
|
# and copy my_print_defaults to /usr/bin
|
|
# - Add the path to the mysql-installation-directory to the basedir variable
|
|
# below.
|
|
#
|
|
# If you want to affect other MySQL variables, you should make your changes
|
|
# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
