本文介绍如何通过编辑MySQL配置文件my.cnf来设置服务器的默认字符集为UTF-8，并展示了如何验证字符集设置是否成功。

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 -p
mysql> use root
mysql> 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
