MySQL 清密码:专治-----ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

时间:2022-08-08 19:22:47

/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: <输入新设的密码newpassword>
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: <输入[client]节的密码>
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
mysql>

创建数据库,冒出这一句:
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
mysql>  SET PASSWORD = PASSWORD('123456');
Query OK, 0 rows affected (0.03 sec)

mysql> create database yan1;
Query OK, 1 row affected (0.00 sec)

NND !
