过程:

Open two shell sessions, logging in to one as the Linux root user and the other as a nonroot user with access to the mysql command. In your root session, stop the normal mysqld listener and start a listener which bypasses password authentication (note: this is a significant security risk as anyone with access to the mysql command may access your databases without a password. You may want to close active shell sessions and/or disable shell access before doing this): # systemctl stop mysqld # /usr/sbin/mysqld --skip-grant-tables -u mysql & In your nonroot session, log in to mysql and set the mysql root password: $ mysql mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass'); Query OK, 0 rows affected, 1 warning (0.01 sec) mysql> quit; In your root session, kill the passwordless instance of mysqld and restore the normal mysqld listener to service: # kill %1 # systemctl start mysqld In your nonroot session, test the new root password you configured above: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. ... mysql>

根据MySql版本的不同，该过程有所不同。按照您的版本所描述的步骤进行操作:

HINTS - Read before the instructions page for your version of MySql* In step 5: Instead of run CMD, create a shortcut on your desktop calling CDM.exe. Then right-click on the shortcut and select "Execute as Administrator". In step 6: Skip the first proposed version of the command and execute the second one, the one with the --defaults-file parameter Once you execute the command, if everything is ok, the CMD window remains open and the command of step 6 continues executing. Simply close the window (click 'x'), and then force close MySQl from the Task Manager. Delete the file with the SQL commands, and start again MySQL. The password must be changed now.

…只需在链接中更改版本(5.5,5.6,5.7)

这里提供的答案似乎对我不起作用，事实证明，诀窍是: ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password

(完整的答案在这里:在MySQL 5.7用" plugin: auth_socket "修改用户密码)

我用另一种方法解决了这个问题，这对一些人来说可能更简单。

我这样做是因为我尝试在安全模式下启动，但无法连接到错误: ERROR 2002 (HY000):无法通过socket '/var/run/mysqld/mysqld连接到本地MySQL服务器。袜子”(2)

我所做的就是以root用户正常连接:

$ sudo mysql -u root

然后我创建了一个新的超级用户:

mysql> grant all privileges on *.* to 'myuser'@'%' identified by 'mypassword' with grant option;
mysql> quit

然后以myuser身份登录

$ mysql -u myuser -p -h localhost

尝试更改密码没有给我任何错误，但对我没有任何帮助，所以我放弃并重新创建根用户

mysql> drop user 'root'@'localhost;
mysql> mysql> grant all privileges on *.* to 'root'@'localhost' identified by 'mypassword' with grant option;

根用户现在正在使用新密码

使用Debian / Ubuntu mysql包，可以使用Debian -sys- maintenance用户登录，该用户拥有所有的权限，密码保存在/etc/mysql/ Debian .cnf文件中
