安装时MySQL默认的字符集是latin1，插入表中的中文会显示异常，所以需要修改字符集。
1、修改Mysql字符集为UTF-8的方法：
在/etc/my.cnf加入如下命令，重启MySQL服务即可：
[client]字段里加入 default-character-set=utf8
[mysqld]字段里加入 character-set-server=utf8
[mysql]字段里加入 default-character-set=utf8
2、查看字符集命令：show variables like '%char%';
修改前：
mysql> show variables like '%char%';
+--------------------------------------+----------------------------+
| Variable_name | Value |
+--------------------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
| validate_password_special_char_count | 1 |
+--------------------------------------+----------------------------+
9 rows in set (0.00 sec)
修改后：
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/share/mysql/charsets/ |
| validate_password_special_char_count | 1 |
+--------------------------------------+----------------------------+
9 rows in set (0.01 sec)
