What should I do if I forget mysql password?

When you forget your MySQL password, don't panic, there are several methods to help you restore access to the database. In this article, I will introduce you to some common methods so that you can regain access to your MySQL database.

1. Use the mysqladmin command to reset the password: This is a simple and fast method. Open a terminal (or command line window) and enter the following command:

mysqladmin-uroot-ppassword'new_password'
Copy after login

Be sure to replace 'new_password' with the new password you want to set. Then press Enter key to prompt for the old password. If the old password is correct, the system will automatically change the password and display a successful password change message.

2. Use mysqld_safe to reset the password: This method is only applicable if you have system administrator rights. First, stop the MySQL service. Then, enter the following command in the terminal:

mysqld_safe--skip-grant-tables&
Copy after login

This will start the MySQL service and skip access control. Next, open another terminal window and enter the following command to connect to the database server:

mysql-uroot
Copy after login
Copy after login

Then, use the following SQL command to reset the password:

FLUSHPRIVILEGES;
ALTERUSER'root'@'localhost'IDENTIFIEDBY'new_password';
Copy after login
Copy after login

Remember to replace 'new_password' with The new password you want to set. Then, shut down MySQL by entering the "quit" command.

3. Modify the MySQL configuration file: This method is suitable for situations where you have system administrator rights and can directly access the MySQL configuration file. First, stop the MySQL service. Then, enter the following command in the terminal to open the configuration file:

sudonano/etc/mysql/my.cnf
Copy after login

Find the following line in the file:

[mysqld]
Copy after login

Add the following line below it:

skip-grant-tables
Copy after login

Then Save the file and close the editor. Restart the MySQL service. Now, you can use the following command to access the database and reset the password:

mysql-uroot
Copy after login
Copy after login

Then, use the following SQL command to reset the password:

FLUSHPRIVILEGES;
ALTERUSER'root'@'localhost'IDENTIFIEDBY'new_password';
Copy after login
Copy after login

Remember to replace 'new_password' with what you want to set new password. Finally, by typing "quit" The command shuts down MySQL and removes the added lines from the configuration file. Restart the MySQL service.

Please note that these methods require corresponding permissions to execute. If you do not have the appropriate permissions, contact your system administrator or database administrator for help.

In order to avoid forgetting your password in the future, we strongly recommend that you keep your password properly and change it regularly.
