查看和设置MySQL数据库字符集 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> 其他的一些设置方法： 修改数据库的字符集 mysql>use mydb mysql>alter database mydb character set utf-8; 创建数据库指定数据库的字符集 mysql>create database mydb character set utf-8; 通过配置文件修改: 修改/var/lib/mysql/mydb/db.opt default-character-set=latin1 default-collation=latin1_swedish_ci 为 default-character-set=utf8 default-collation=utf8_general_ci 重起MySQL: [root@bogon ~]# /etc/rc.d/init.d/mysql restart 通过MySQL命令行修改: mysql> set character_set_client=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_connection=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_database=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_results=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_server=utf8; Query OK, 0 rows affected (0.00 sec) mysql> set character_set_system=utf8; Query OK, 0 rows affected (0.01 sec) mysql> set collation_connection=utf8; Query OK, 0 rows affected (0.01 sec) mysql> set collation_database=utf8; Query OK, 0 rows affected (0.01 sec) mysql> set collation_server=utf8; Query OK, 0 rows affected (0.01 sec) 查看: 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 (0.03 sec) 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 (0.04 sec) [@more@] （编辑：昌吉站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
