首先停mysql服務(wù),編輯配置文件my.cnf

$?sudo?stop?mysql

$sudo?vim?/etc/mysql/my.cnf

[client]

default-character-set=utf8?#增加這一行，指定字符集

port????????????=?3306

socket??????????=?/var/run/mysqld/mysqld.sock

.............

[mysqld]

character_set_server=utf8?#增加這一行，指定字符集

user????????????=?mysql

pid-file????????=?/var/run/mysqld/mysqld.pid

重啟服務(wù)，字符集就成了UTF-8

$?sudo?start?mysql

$?sudo?mysql?-uroot?-p

mysql>?use?root

mysql>?show?variables?like?'%char%'?;#更改前存在的用戶字符集不會(huì)改變，以后新建的用戶字符集都變成了UTF-8
