mysql 默认编码改utf8

vim /etc/mysql/my.cnf

执行以下操作：

1、在[client]字段里加入default-character-set=utf8，如下：

[client]

port = 3306

socket = /var/lib/mysql/mysql.sock

default-character-set=utf8

2、在[mysqld]字段里加入character-set-server=utf8，如下：

[mysqld]

port = 3306

socket = /var/lib/mysql/mysql.sock

character-set-server=utf8

3、在[mysql]字段里加入default-character-set=utf8，如下：

[mysql]

no-auto-rehash

default-character-set=utf8

show variables like 'character%' 可查看mysql编码方式，修改完成后是这样的：
