# Description: MySQL is a very fast and reliable SQL database engine.
### END INIT INFO
# If you install MySQL on some other places than /usr/local/mysql,
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.
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.
