  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

  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.

  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_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/ |
  +--------------------------+----------------------------+
  8 rows in set (0.02 sec)
  mysql>
