解决用navicat远程连接数据库出现1045 access denied for user 'root'@'localhost' using password yes

 

在mysql命令行中执行

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456XXX'); 

GRANT ALL PRIVILEGES ON *.* TO 'root' @'%' IDENTIFIED BY '123456XXX' WITH GRANT OPTION;

flush privileges;

 

若以上方法行不通则用：

use mysql; 

UPDATE user SET Password=PASSWORD('123456') where USER='root';

flush privileges;
