转载自廖雪峰-->在Mac或Linux上，需要编辑MySQL的配置文件，把数据库默认的编码全部改为UTF-8。MySQL的配置文件默认存放在/etc/my.cnf
或者/etc/mysql/my.cnf：
[client]
default-character-set = utf8
[mysqld]
default-storage-engine = INNODB
character-set-server = utf8
collation-server = utf8_general_c
重启MySQL后，可以通过MySQL的客户端命令行检查编码：
sudo service mysql restart
mysql -u root -p
Enter password:
Welcome to the MySQL monitor...
...
mysql> show variables like '%char%';+--------------------------+--------------------------------------------------------+| Variable_name | Value |+--------------------------+--------------------------------------------------------+| character_set_client | utf8 || character_set_connection | utf8 || character_set_database | utf8 || character_set_filesystem | binary || character_set_results | utf8 || character_set_server | utf8 || character_set_system | utf8 || character_sets_dir | /usr/local/mysql-5.1.65-osx10.6-x86_64/share/charsets/ |+--------------------------+--------------------------------------------------------+8 rows in set (0.00 sec)
看到utf8
字样就表示编码设置正确。
