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.
