Windows下
mysqld -nt --skip-grant-tables
mysqladmin -u root flush-privileges password "newpassword"
----------------------------------------
提示:1045 access denied for user 'root'@'localhost' using password yes
前几天都好好的,昨天没弄,结果今天晚上过来提示上面的这个错误,重启mysql还是不可以
网上的方法看了几个但是不知道怎么弄
方法一:
# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit
# /etc/init.d/mysql restart
# mysql -uroot -p
Enter password:
mysql>
方法二:
直接使用/etc/mysql/debian.cnf文件中[client]节提供的用户名和密码:
# mysql -udebian-sys-maint -p
Enter password:
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit
# mysql -uroot -p
Enter password:
mysql>

另一个方法
Windows:
1. 管理员登陆系统,停止mysql服务或者结束mysqld-nt进程
2. 进入命令行,来到mysql的安装目录.假设安装目录为 d:/mysql/ , CMD进入命令行
3. 运行 d:/mysql/bin/mysqld-nt --skip-grant-tables 启动mysql,关闭权限的检查
4. 运行 d:/mysql/bin/mysqladmin -u root flush-privileges password "newpassword" 重设root密码
5. 重新启动mysql服务
第4步也可以直接修改mysql表,所用到的SQL语句同linux部分,这里就不再重复了.
