# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M – 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# 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]
#character-set-server=utf8
#password = your_password
#host = localhost
port = 3306
socket = /tmp/mysql.sock
# Here follows entries for some specific programs

内存太小，加点SWAP:
dd if=/dev/zero of=/swapfile bs=1M count=1024 #增加1G的SWAP进去
mkswap /swapfile
swapon /swapfile
free
添加这行： /swapfile swap swap defaults 0 0 到 /etc/fstab
