# 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.  

#  

# MySQL programs look for option files in a set of  

# locations which depend on the deployment platform.  

# You can copy this option file to one of those  

# locations. For information about these locations, see:  

# http://dev.mysql.com/doc/mysql/en/option-files.html  

#  

# 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]  

default-character-set=utf8
