升級到Mysql8 后的連接問題和允許遠程訪問

1.Navicat連MySql8報錯的問題

用mysql命令行登陸mysql，執行以下命令，修改加密方式

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
mysql> FLUSH PRIVILEGES;

2.允許遠程連接Mysql8

mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'root';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
mysql> flush privileges;
