How to retrieve the mysql password (linux/windows)

We often forget the password of mysqlroot, so how can we find it? re-installation is too difficult to configure, next, let me introduce two methods to retrieve passwords in linux and mysql.

Like * UNIX version:

The following is an incorrect answer:

First stop the MySQL service and start it with the skip-grant-tables parameter:

The Code is as follows:
Shell>/etc/init. d/stop Shell> mysqld_safe -- skip-grant-tables & in this case, you can access the MySQL command line without authorization and use SQL to reset the MySQL password: UPDATE mysql. user SET Password = PASSWORD ('... ') WHERE User = '... 'AND Host = '... ';

Flush privileges; why is it an incorrect answer? After you simply use the skip-grant-tables parameter to start the service, unless the server shields Internet access, other users except themselves may also access the database, although it takes a short time to reset the password, as the saying goes, if you are not afraid of thieves, you will be afraid of thieves. Any leaks may cause a big disaster.

The following is the correct answer:

The key point is to add the skip-networking parameter while using the skip-grant-tables parameter:

The Code is as follows:
Shell> mysqld_safe -- skip-grant-tables -- skip-networking

& After using SQL to reset the password, remember to remove skip-networking and restart the MySQL service in a normal way:

The Code is as follows:
Shell>/etc/init. d/mysqld restart

The above method needs to restart the service twice. In fact, it is more elegant. Restart the service once:

First, save the SQL statement used to a text file (/path/to/init/file ):

The Code is as follows:
UPDATE mysql. user SET Password = PASSWORD ('...') WHERE User = '...' AND Host = '...'; Flush privileges; then, use the init-file parameter to start the MySQL service, Shell>/etc/init. d/mysql stop Shell> mysqld_safe -- init-file =/path/to/init/file

& In this case, the password has been reset. Do not forget to delete the file to avoid leaking the password.

Tip: the parameters used in this article are passed through the command line mysqld_safe, and can also be passed through my. cnf.

Windows version:

1. log on to the system as a system administrator.
2. Open cmd ----- net start to check whether mysql is started. If it is enabled, the net stop mysql will be stopped.
3. Install mysql in d: mysql5bin.
4. Skip the permission check and start mysql.
D: mysql5binmysqld-nt -- skip-grant-tables -- skip-networking
5. Open cmd again. Enter d: mysql5bin:
D: mysql5binmysqladmin-uroot flush-privileges password "newpassword"
D: mysql5binmysqladmin-u root-p shutdown prompts you to re-enter the password.
6. net start mysql in cmd
7. You have done it.
