（运行如下命令即可查看编码方式）
# mysql -u root -p
Enter password:
mysql > show variables like "character%";
编码显示：
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
1.要修改编码方式则找到mysql安装目录下的配置文件（.cnf文件），一般至少有四个配置文件：mysql-huge.cnf mysql-medium.cnf mysql-small.cnf mysql mysql-large.cnf 这四个配置文件我们只需拷贝其中一个文件到目录/etc下并重命名为my.cnf，若不拷贝到此目录下则重启Mysql后编码方式又回到默认方式，就是因为这个我整了半天。只要拷贝到/etc目录下就永久的修改了编码方式。
2.修改文件my.cnf：
init_connect=SET NAMES 'utf8'
3.重启Mysql：
# service mysql restart
再查看编码方式即改为了所需编码方式，如下：
+--------------------------+----------------------------+
| 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/share/mysql/charsets/ |
