mysql rpm安装后的密码修改_MySQL
由于在fedora下用 mysql官方源安装myslq后,root用户密码为随机生成,没找到默认密码文件在哪里,导致找不到方法进入数据库。
以下是解决过程,记录下来以备后患:
解决mysql“Access denied for user 'root'@'localhost'”
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)
还是不行。
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)'
悲剧啊!!
最后找到了解决方法,如下(感谢网络,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') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
输入mysql -u root -p
输入新修改的密码成功登录。
