在Linux机器上使用Mysql客户端访问获取中文有时候是乱码，如下：
mysql> select * from t_user;
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+
| id | user_name | user_phone | user_email | user_pwd | pwd_salt | create_time | modify_time | is_delete |
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+

+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+
3 rows in set (0.00 sec)
这时候，看一下Mysql的字符集，并且把它设成和数据库（表）一样的字符集：
mysql> select @variable like 'character_set_results';
+----------------------------------------+
| @variable like 'character_set_results' |
+----------------------------------------+
| NULL |
+----------------------------------------+
1 row in set (0.00 sec)mysql> set character_set_results='utf8';
Query OK, 0 rows affected (0.00 sec)
然后，再查询就能够得到正常的汉字了：
mysql> select * from t_user;
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+
| id | user_name | user_phone | user_email | user_pwd | pwd_salt | create_time | modify_time | is_delete |
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+
