Ubuntu
首先停mysql服务,编辑配置文件my.cnf
$ sudo stop mysql$sudo vim /etc/mysql/my.cnf
[client] default-character-set=utf8 #增加这一行，指定字符集port = 3306 socket = /var/run/mysqld/mysqld.sock .............[mysqld] character_set_server=utf8 #增加这一行，指定字符集user = mysql pid-file = /var/run/mysqld/mysqld.pid
重启服务，字符集就成了UTF-8
$ sudo start mysql$ sudo mysql -uroot -pmysql> use rootmysql> show variables like '%char%' ;#更改前存在的用户字符集不会改变，以后新建的用户字符集都变成了UTF-8+--------------------------+----------------------------+| Variable_name | Value |+--------------------------+----------------------------+| character_set_client | utf8 || character_set_connection | utf8 || character_set_database | latin1 || character_set_filesystem | binary || character_set_results | utf8 || character_set_server | utf8 || character_set_system | utf8 || character_sets_dir | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+mysql> create database mydb;mysql> use mydbmysql> show variables like '%char%';+--------------------------+----------------------------+| 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/ |+--------------------------+----------------------------+
