mysql8.0授权远程登录

之前一直用mysql5.6 远程授权登录，后来换mysql8.0原来的授权方式报错

mysql> grant all privileges on *.*  to  'root'@'%'  identified by 'root'  with grant option;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'identified by 'root'  with grant option' at line 1
mysql> create user 'brady'@'%' identified by 'brady';
Query OK, 0 rows affected (0.02 sec)

8.0授权方式不一样 

不能授权给自己

root@a21073c9b9f7:/# mysql -uroot -p

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

先创建一个其他用户

mysql> create user 'brady'@'%' identified by 'brady';
Query OK, 0 rows affected (0.02 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'brady'@'%';
Query OK, 0 rows affected (0.04 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> ALTER USER 'brady'@'%' IDENTIFIED WITH mysql_native_password BY 'brady'; 
Query OK, 0 rows affected (0.02 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

如果用Navicat连接的回报不支持caching_sha2_password验证方式的错误。

将远程访问用户的验证方式改为： msyql_native_password 

执行：

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

FLUSH PRIVILEGES;
