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

解决用navicat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;
