更新ubuntu之后无法登陆mysql

Posted 2021-01-31 robotech_erx

Ubuntu 14.04，更新一些软件之后莫名其妙的mysql无法登陆了，一直显示：“Access denied for user ‘root‘@‘localhost‘”

 

重置root密码后就好了，重置方法：

You have to reset the password! steps for mac osx(tested and working) and ubuntu

 

Stop MySQL

 

$ sudo service mysql stop

Start it in safe mode:

 

$ sudo mysqld_safe --skip-grant-tables

(above line is the whole command)

 

This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:

 

$ mysql -u root

 

mysql> UPDATE mysql.user SET Password=PASSWORD(‘password‘) WHERE User=‘root‘;

Start MySQL

 

sudo service mysql start

your new password is ‘password‘.

评论里说这么整不安全，帖子里还有更安全的方法，没有深究。
