即使我使用以下命令重置了超级用户密码,我也无法登录到MySQL:(列出的其他命令提供了更多信息)
# sudo dpkg-reconfigure mysql-server-5.1
# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
# telnet 127.0.0.1 3306
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
# ps -Aw |grep mysql
26522 ? 00:00:00 mysqld
# /etc/init.d/mysql start
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql start
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start mysql更新:
# sudo mysqladmin -u root password 123
mysqladmin: connect to server at 'localhost' failedMySQL似乎没有正常运行
更新:我使用的是Ubuntu下的MySQL 5.1。在我对my.cnf进行了一些更改以启用远程访问之前,它是可以使用的。我撤消了我的更改,但问题没有解决!(也许我忘了撤消某些事情!)
更新:
# service mysql status
mysql start/running, process 26650
# /etc/init.d/mysql status
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql status
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the status(8) utility, e.g. status mysql

要设置root密码,请执行以下操作:
mysqladmin -u root password NEWPASSWORD要恢复它:http://www.cyberciti.biz/tips/recover-mysql-root-password.html

我最好的猜测是,如果您重新配置/重新安装了MySQL,则需要在没有密码的情况下登录,例如:
mysql -u root
甚至是
mysql
Edit:要查看服务是否正在运行,您可以尝试:
service mysqld status
如果它没有运行,请尝试:
service mysqld start然后再次检查状态。

看起来MySQL肯定没有运行。您可以使用/etc/init.d/mysqld status或service mysqld status验证这一点(不要直接链接到服务命令)。
我敏锐的感觉告诉我,你的or或MySQL安装执行得不正确。了解更多关于(linux?)您正在运行的环境,以及它是如何配置的(或者是谁配置的,在PaaS的情况下)。
