一、查看字符集编码：
登录mysql
show variables like '%character%';
二、修改编码：
编辑/etc/my.cnf ，设置后的配置文件如下：
[root@node03 /]# cat /etc/my.cnf [mysql]default-character-set=utf8[mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysql# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0default-character-set=utf8character_set_server=utf8#lower_case_table_names=1 忽略大小写
[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.piddefault-character-set=utf8[mysql.server]default-character-set=utf8[client]default-character-set=utf8
三、重启MySQL服务：
service mysql restart
四、如果上面的都修改了还乱码，那剩下问题就一定在connection连接层上。解决方法是在发送查询前执行一下下面这句（直接写在SQL文件的最前面）：
SET NAMES 'utf8';
它相当于下面的三句指令：SET character_set_client = utf8;SET character_set_results = utf8;SET character_set_connection = utf8;
执行show variables like 'character%' 跟下面一样说明修改成功
