我的mysql配置文件

# clients (those using the mysqlclient10 compatibility package).

# Disabling symbolic-links is recommended to prevent assorted security risks;

max_allowed_packet=10M

[mysqld_safe]

pid-file=/var/run/mysqld/mysqld.pid

[client]
default-character-set=utf8

MySQL5.5以后default-character-set=utf8替换成character-set-server=utf8

 

比较专业的配置：
