MySQL8.0新特性

1、修改密码
修改root密码以前要先flush privileges;
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'fanjinbao_%@!';

2、添加用户
CREATE USER `fansik`@`%` IDENTIFIED BY 'fanjinbao_%@!';GRANT ALL ON *.* TO `fansik`@`%` WITH GRANT OPTION;
FLUSH PRIVILEGES;
若是添加的用户在用navicat登陆是报client does not support authentication错误
ALTER USER 'fansik'@'%' IDENTIFIED WITH mysql_native_password BY 'fanjinbao_%@!';
FLUSH PRIVILEGES;
