mysql5.7版本语法：SET PASSWORD FOR 'root'@'localhost' = PASSWORD('password123');

mysql5.7之后版本语法： ALTER user 'root'@'localhost' IDENTIFIED BY 'password1'

mysql> CREATE USER 'test'@'localhost' IDENTIFIED BY 'pwd123456';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'test'@'localhost' WITH GRANT OPTION;

mysql> CREATE USER 'test'@'%' IDENTIFIED BY 'pwd123456';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' WITH GRANT OPTION;

Navicat 无法连接

查看用户信息

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

mysql> ALTER USER 'test'@'%' IDENTIFIED WITH mysql_native_password BY 'pwd123456';

mysql> ALTER USER 'test'@'localhost' IDENTIFIED WITH mysql_native_password BY 'pwd123456';

ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';

 视频里面的修改 root 密码的sql会提示有语法错误，使用官方文档里面的sql语句是没有问题的

Navicat mysql客户端

docker exec -it mysql01 bash 进入容器命令

mysql 命令

mysql -u localhost root -p 登录mysql

user mysql

select user ,host from user
