MySQL 8.0 配置mysql_native_password身份验证插件的密码

mysql8.0的默认密码验证不再是password。所以在创建用户时，create user 'username'@'%' identified by 'password'; 客户端是无法连接服务的。

方法一：

登录MySQL后输入：

ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

FLUSH PRIVILEGES;

方法二：

编辑my.cnf文件，更改默认的身份认证插件。比如说：

vim /data/mysql/mysql_3306/my_3306.cnf

# 在[mysqld]中添加下边的代码
default_authentication_plugin=mysql_native_password

这个需要重启服务才生效。

mysql> select user,host,plugin from mysql.user;
