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

### BEGIN INIT INFO

# Provides: mysql

# Required-Start: $local_fs $network $remote_fs

# Required-Stop: $local_fs $network $remote_fs

# Default-Start: 2 3 4 5

# Default-Stop: 0 1 6

# Short-Description: start and stop MySQL

# 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.
