解决mysql中无法显示中文的一个实例

1 登录数据库

amp1:~ # mysql -uroot -pmysql.rzrk
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2132
Server version: 5.0.95-log SUSE MySQL RPM
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

2 使用xiaobing库

mysql> use xiaobing;
Database changed

3 查xiaobing库中的表

mysql> show tables;
+--------------------+
| Tables_in_xiaobing |
+--------------------+
| luzhi          |
| t1            |
+--------------------+
2 rows in set (0.00 sec)

4 查表luzhi的表结构

mysql> desc luzhi;
+-------+----------+------+-----+---------+-------+
| Field | Type    | Null | Key | Default | Extra |
+-------+----------+------+-----+---------+-------+
| id   | int(10)  | YES  |   | NULL   |     |
| name  | char(30) | YES  |   | NULL   |     |
+-------+----------+------+-----+---------+-------+
2 rows in set (0.00 sec)

5 查看表luzhi的数据

mysql> seclect * from luzhi;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'seclect * from luzhi' at line 1
mysql> select * from luzhi;
+------+-------+
| id  | name  |
+------+-------+
|   2 | o`    |
|    4 | f    |
+------+-------+
4 rows in set (0.00 sec)   ##发现输出为乱码

6 查当前数据库所使用的字符编码

mysql> show variables like "character%";
+--------------------------+----------------------------+
| Variable_name        | Value                 |
+--------------------------+----------------------------+
| character_set_client    | gbk                 |
| character_set_connection | gbk                |
| character_set_database  | gbk                |
| character_set_filesystem | binary              |
| character_set_results   | gbk                 |
| character_set_server    | gbk                 |
| character_set_system    | utf8                |
| character_sets_dir     | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

7 临时性的更改当前的数据编码

set names utf8;

相当于：

SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;

mysql> set names utf8;
Query OK, 0 rows affected (0.00 sec)

8 查看是否成功修改了

mysql> show variables like "character%"
-> ;
+--------------------------+----------------------------+
| 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    | gbk                |
| character_set_system    | utf8                |
| character_sets_dir     | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
9 再次查询表luzhi的数据，发现可以正常显示
mysql> select * from luzhi;
+------+---------+
| id  | name   |
+------+---------+
|   2 | 你好   |
|   4 | 甪直   |
+------+---------+
4 rows in set (0.01 sec)

10 上面的方法只是临时的更改，当退出mysql再次进入的就会失效了。
永久更改：

#vim /etc/my.cnf

[client]
#password       = your_password
port            = 3306
socket          = /var/lib/mysql/mysql.sock
default-character-set=gbk  #这里可以设置你所需要定义的编码 utf8
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
port            = 3306
socket          = /var/lib/mysql/mysql.sock
datadir = /home/rzrk/mysql
skip-locking
key_buffer = 16M
max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
default-character-set=gbk  #这里可以设置你所需要定义的编码 utf8

修改完成后必须重启mysql才能生效

#service mysql restart
#mysql uroot -p
> show variables like "character%";
