ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES) 的解决方案

目前博主解决这个问题的主要是以下两张方法。方法二来得快，有时间的话还是推荐方法一。

方法一：

#1.停止mysql数据库
/etc/init.d/mysqld stop#2.执行如下命令
mysqld_safe --user=mysql --skip-grant-tables --skip-networking &#3.使用root登录mysql数据库
mysql -u root mysql#4.更新root密码
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
#最新版MySQL请采用如下SQL：
mysql> UPDATE user SET authentication_string=PASSWORD('newpassword') where USER='root';#5.刷新权限
mysql> FLUSH PRIVILEGES;#6.退出mysql
mysql> quit#7.重启mysql
/etc/init.d/mysqld restart#8.使用root用户重新登录mysql
mysql -uroot -p
Enter password: <输入新设的密码newpassword>

方法二：

直接输入mysql回车就好了，不要加-u -p参数，就会使用默认的root@localhost登录。
