MySQL Recover password

1, first confirm the server out of security state, that is, no one can arbitrarily connect to MySQL database. Because the MySQL database is completely out of password-protected state during the reset of the root password of MySQL, other users can log in and modify the MySQL information arbitrarily. It is possible to implement the server's quasi-security state by enclosing MySQL's external ports and stopping Apache and all user processes. The safest state is to operate on the console of the server and unplug the network cable.
2, modify the MySQL login settings;

Vim/etc/my.cnf

Add one sentence to the paragraph in [mysqld]: Skip-grant-tables Save and exit Vim.
3. Restart mysqld;

Service mysqld Restart # or/etc/init.d/mysqld restart

4, log in and modify the root password of MySQL;

1.mysql>; Use MySQL;2.mysql>; UPDATE user SET Password = Password (' New-password ') WHERE user = ' root ';3.mysql>; Flush Privileges;4.mysql>; Quit

5, the MySQL login settings to change back;

Vim/etc/my.cnf

Delete the skip-grant-tables that was added in the paragraph of [mysqld] just now;
Save and exit Vim.
6, restart mysqld;

Service mysqld Restart # or/etc/init.d/mysqld restart

7, restore the normal working state of the server;
Reverse the action in step one. Restores the server's working status.
