linux下 mysql字符集的修改

1.查找/etc目录下是否有my.cnf文件；

#ls -l | grep my.cnf (在/etc下查找是否有my.cnf文件存在)

2.如果没有就要从/usr/share/mysql,拷贝一个到/etc 下，在/usr/share/mysql目录下有五个后缀为.cnf的文件，分别是 my-huge.cnf my-innodb-heavy-4G.cnf my-large.cnf my-medium.cnf my-small.cnf ；从中随便拷贝一个到/etc目录下并将其改为my.cnf文件

3.修改my.cnf文件

#vi /etc/my.cnf

[client]

default-character-set=utf8

[mysqld]

character-set-server=utf8

[mysql]

default-character-set=utf8

mysql> show variables like 'character_set%' ;
