# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/var) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
#password = your_password
port  = 3306
socket  = /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# (using the "enable-named-pipe" option) will render mysqld useless!

实际上最主要的就是添加红色部分的设置。
