mysql字符集设置[摘]

linux下/etc/mysql/my.cnf(windows下my.ini)

[client] 下添加
default-character-set=utf8 默认字符集为utf8
[mysqld] 添加
default-character-set=utf8 默认字符集为utf8
#character-set-server=utf8
collation-server=utf8_general_ci
init_connect='set collation_connection=utf8_general_ci'
init_connect='set names utf8' (设定连接mysql数据库时使用utf8编码，以让mysql数据库为utf8运行;
注意该参数对于连接数据库的用户是超级用户组的用户将被忽略，这样是为了避免该参数导致数据库致命错误，而无法使用任何一个用户连接上修改该项配置)

修改好后，重新启动mysql 即可，查询一下show variables like 'character%';
