Why Am I Getting 'ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded' When Connecting to MySQL?

Troubleshooting MySQL Authentication Failure: "ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded"

When establishing a connection to a MySQL database, users might encounter the error message "ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded," indicating an authentication plugin issue.

To resolve this specific error and successfully log into MySQL, it's important to address the following steps:

1. Reset the Root Password with 'mysql_native_password' Plugin:

   • Reset the root password using the command provided in the provided solution, but ensure to set the authentication plugin to "mysql_native_password." This prevents conflicting plugin errors later on.

2. Restart MySQL Service:

   • Stop the MySQL service using "/etc/init.d/mysql stop."
   • Start MySQL without using password authentication by executing "mysqld_safe --skip-grant-tables &."

3. Execute MySQL Commands:

   • Connect to MySQL as root without a password ("mysql -uroot").
   • Update the root user's authentication plugin to "mysql_native_password" using the provided SQL commands.

4. Restart MySQL Service Again:

   • Stop MySQL using "/etc/init.d/mysql stop."
   • Start MySQL by executing "/etc/init.d/mysql start."

5. Log In to Database:

   • Attempt to log in to MySQL using "mysql -u root -p." Since the password is now blank, simply press 'Enter.'

6. Address Socket Issues (Optional):

   • Should a socket error be encountered, you can try creating the directory "/var/run/mysqld" with appropriate owner permissions or using the alternative provided commands in the solution.

By following these steps, you can effectively resolve the "ERROR 1524" plugin not loaded error and establish a successful connection to your MySQL database.
