设置MySQL设置字符集和排序方式

1. 编辑/etc/my.cnf文件, 在"[client]"下添加"default-character-set=utf8"
2. 编辑/etc/my.cnf文件, 在"[mysqld]"下添加"default-character-set=utf8"
3. 重新启动mysql服务
# sudo /etc/init.d/mysqld restart
* 查看系统字符集和排序方式

mysql> SHOW VARIABLES LIKE 'collation/_%'; +--------------------------+--------+ | 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 | +--------------------------+--------+ mysql> SHOW VARIABLES LIKE 'character/_set/_%'; +----------------------+-----------------+ | Variable_name | Value | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database | utf8_bin | | collation_server | utf8_general_ci | +----------------------+-----------------+

4. 设置数据库字符集
mysql> create database <database> default character set utf8 default collate utf8_bin;
或者修改已有数据库
mysql> alter database <database> default character set utf8 default collate utf8_bin;

* 查看mysql支持的所有的COLLATION
mysql> SHOW COLLATION;
