START / STOP / RESTART MYSQL SERVER

MySql will start on boot time. You can also type manually (as root) to start / stop / restart the server:

# /etc/init.d/mysql start
# /etc/init.d/mysql stop
# /etc/init.d/mysql restart
# /etc/init.d/mysql status

or

# service mysql start
# service mysql stop
# service mysql restart
# service mysql status

MySql Server Configuration

The MySQL database server configuration file is located at /etc/mysql/my.cnf. Edit the file using a text editor such as vi, type:

# vi /etc/mysql/my.cnf
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
