ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

问题描述:

[root@11203ora ~]# mysql -uroot -parcerzhang

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

解决方法:

# /etc/init.d/mysqld 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/mysqld restart 
# mysql -uroot -p 
Enter password: <输入新设的密码newpassword> 
mysql>

注意：PASSWORD('newpassword')函数中的newpassword要修改成实际的newpassword.
