Liunx环境下MySQL字符集的修改方法

MySQL字符集的修改在不同的环境下有不同的方法，下面为您介绍的是在Liunx环境下MySQL字符集的修改方法，如果您对此方面感兴趣的话，不妨一看。

Liunx下修改MySQL字符集：

1.查找MySQL的cnf文件的位置

find / -iname '*.cnf' -print  
 
/usr/share/mysql/my-innodb-heavy-4G.cnf  
/usr/share/mysql/my-large.cnf  
/usr/share/mysql/my-small.cnf  
/usr/share/mysql/my-medium.cnf  
/usr/share/mysql/my-huge.cnf  
/usr/share/texmf/web2c/texmf.cnf  
/usr/share/texmf/web2c/mktex.cnf  
/usr/share/texmf/web2c/fmtutil.cnf  
/usr/share/texmf/tex/xmltex/xmltexfmtutil.cnf  
/usr/share/texmf/tex/jadetex/jadefmtutil.cnf  
/usr/share/doc/MySQL-server-community-5.1.22/my-innodb-heavy-4G.cnf  
/usr/share/doc/MySQL-server-community-5.1.22/my-large.cnf  
/usr/share/doc/MySQL-server-community-5.1.22/my-small.cnf  
/usr/share/doc/MySQL-server-community-5.1.22/my-medium.cnf  
/usr/share/doc/MySQL-server-community-5.1.22/my-huge.cnf

2. 拷贝 small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4G.cnf其中的一个到/etc下，命名为my.cnf

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

#p#3. 修改my.cnf

vi /etc/my.cnf

在[client]下添加

default-character-set=utf8

在[mysqld]下添加

default-character-set=utf8

4.重新启动MySQL

[root@bogon ~]# /etc/rc.d/init.d/mysql restart  
Shutting down MySQL                                        [ 确定 ]  
Starting MySQL.                                            [ 确定 ]  
[root@bogon ~]# mysql -u root -p  
Enter password:  
Welcome to the MySQL monitor. Commands end with ; or \g.  
Your MySQL connection id is 1  
Server version: 5.1.22-rc-community-log MySQL Community Edition (GPL)  
 
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

#p#5.查看MySQL字符集设置

mysql> show variables like 'collation_%';  
+----------------------+-----------------+  
| Variable_name        | Value           |  
+----------------------+-----------------+  
| collation_connection | utf8_general_ci |  
| collation_database   | utf8_general_ci |  
| collation_server     | utf8_general_ci |  
+----------------------+-----------------+  
3 rows in set (0.02 sec)  
 
mysql> show variables like 'character_set_%';  
+--------------------------+----------------------------+  
| Variable_name            | Value                      |  
+--------------------------+----------------------------+  
| character_set_client     | utf8                       |

| character_set_filesystem | binary                     |  
| character_set_results    | utf8                       |

| character_set_system     | utf8                       |  
| character_sets_dir       | /usr/share/mysql/charsets/ |  
+--------------------------+----------------------------+
