刚使用mysql, 就老是碰到这个问题,真是郁闷, 终于找到原因..
C:Program FilesMySQLMySQL Server 5.0in>mysql
ERROR 1045 (28000): Access denied for user
'ODBC'@'localhost' (usingpassword: N
O)
解决方法:
Step 1:
C:Program FilesMySQLMySQL Server 5.0in>mysql -u root-p
Enter password: ******
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 28 to server version:5.0.24a-community-nt
Type 'help;' or 'h' for help. Type 'c' to clear thebuffer.
Step 2:
C:Program FilesMySQLMySQL Server 5.0in>mysql
mysql>status
正常使用....
------------------------------------------------
我的系统是ubuntu6.06,最近新装好的mysql在进入mysql工具时,总是有错误提示:
# mysql -uroot -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost'(using password: NO)
使用网上介绍的方法修改root用户的密码:
# mysqladmin -uroot -p password 'newpassword'
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password:YES)'
现在终于被我找到了解决方法,如下(请先测试方法三,谢谢!):
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') whereUSER='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') whereUSER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
mysql>
方法三:
这种方法我没有进行过测试,因为我的root用户默认密码已经被我修改过了,那位有空测试一下,把结果告诉我,谢谢!!
# mysql -uroot -p
Enter password:<输入/etc/mysql/debian.cnf文件中[client]节提供的密码>
至此,困惑多时的问题解决了!
