mac mysql password forgotten

In the daily use of computers, it is inevitable that you will encounter the situation of forgetting your password. For example, when using a Mac system, we often need to use a MySQL database. But what if you forget your password for that database? Below I will introduce you in detail how to solve the problem of forgotten Mac MySQL password.

First, we need to determine the MySQL installation path on Mac. Run the following command in the terminal:

which mysql

After executing the above command, if the terminal outputs the following similar information:

/usr/local/bin/mysql

, it means that the MySQL installation path is/usr/local/bin/mysql.

Next, enter the following command in the terminal to restart the MySQL service:

sudo /usr/local/mysql/support-files/mysql.server restart

After executing this command, the system will prompt you to enter the administrator password. Just enter your administrator password.

When the MySQL service restarts successfully, we can try to reset the password in the following way:

sudo /usr/local/mysql/bin/mysql -u root

Here is a little tip: If you cannot access MySQL, please add the port to the above command Number:

sudo /usr/local/mysql/bin/mysql -u root -h 127.0.0.1 -P 端口号

If you don’t know the port number, you can find it in/etc/my.cnfor/etc/mysql/my.cnf.

After you enter the above command, the system will prompt you to enter your password. Since we have forgotten the password, we can do this in the following ways:

1. Enter a blank password to try to log in, or try to log in with an old password.

If neither of these two methods is successful, you can continue with the following operations.

2. Enter the MySQL database through the following command:

use mysql;

3. Clear the password of the existing user:

update user set password=null where user='root';

4. Settings New password:

update user set authentication_string=password('new_password') where user='root';

Replace "new_password" with the new password you want to set.

5. Enter the following command for the password change to take effect:

flush privileges;

After completing the above steps, you should be able to regain access to the MySQL database and log in with the new password. If you still cannot access the database, you can try restarting the system and performing the above operations again.

If you want to avoid the problem of forgetting MySQL passwords, it is recommended that you create a note or notepad to record all passwords, or use a password manager to save passwords. This can effectively avoid the problem of forgetting passwords and better protect your personal information.

In short, when we encounter the problem of forgetting the Mac MySQL password, we should try to reset the password according to the above steps. During the processing, we should operate with caution to ensure that no unnecessary impact is caused to the entire system.
