mysql的字码设置方法

我是按照这篇文章来的https://www.linuxidc.com/Linux/2016-09/135273.htm

但是看样子觉得https://www.cnblogs.com/xiaoluo501395377/archive/2013/05/14/3077880.html这篇文章也像是靠谱的样子

最后放上我的my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
character-set-server = utf8
collation-server = utf8_general_ci
# skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[client]
default-character-set = utf8
