Mysql配置可插入中文

默认情况下，MySQL的字符集是latin1，因此在存储中文的时候，会出现乱码的情况，所以我们需要把字符集统一改成UTF-8。

用vi打开MySQL服务器的配置文件my.cnf

~ sudo vi /etc/mysql/my.cnf

#在[client]标签下，增加客户端的字符编码
[client]
default-character-set=utf8

#在[mysqld]标签下，增加服务器端的字符编码
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci

 重新登陆服务器

~ mysql -uroot -p
Enter password:

# 再次查看字符串编码
mysql> show variables like '%char%';
