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 |
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+

|  2 | ???       | 15985250574 | 1198224554@qq.com | 98bd3a1bebde01ad363d3c5a0d1e56da | 656JHU   | 2016-07-15 23:39:01 | 2016-07-15 23:39:13 |         0 |
|  3 | ???       | 13685250574 | 1256221654@qq.com | 5470db9b63c354f6c8d628b80ae2f3c3 | 89UIKQ   | 2016-07-15 23:39:05 | 2016-07-15 23:39:16 |         0 |
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+
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 |
+----+-----------+-------------+-------------------+----------------------------------+----------+---------------------+---------------------+-----------+
