MySQL Encountering Error 1524: Plugin 'auth_socket' Not Loaded

When attempting to connect to a MySQL database, you may encounter an error message indicating that the 'auth_socket' plugin is not loaded. This issue can arise due to several reasons, and its resolution depends on the specific cause.

Error Cycle and Solutions

Step 1: Socket Issue

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

Solution: Restart the computer or run the commands:

sudo mkdir -p /var/run/mysqld
sudo chown mysql /var/run/mysqld

Step 2: Access Denied

ERROR 1698 (28000): Access denied for user 'root'@'localhost'.

Possible Solution: Reset the root password.

Step 3: Incorrect Auth Plugin

ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded

Solution with Auth Plugin

To resolve the incorrect auth plugin error:

1. Reset the root password.
2. Change the auth plugin to 'mysql_native_password':

use mysql;
update user set authentication_string=PASSWORD('') where User='root';
update user set plugin="mysql_native_password" where User='root';
flush privileges;
quit;

3. Run the following bash commands:

sudo /etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables &
mysql -uroot

4. Paste the following MySQL commands into the CLI:

use mysql;
update user set authentication_string=PASSWORD('') where User='root';
update user set plugin="mysql_native_password" where User='root';
flush privileges;
quit;

5. Run these bash commands:

sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
mysql -u root -p

Blind Paths and Possible Edge Errors

• Use 127.0.0.1 instead of 'localhost' when connecting to MySQL.
• Skip the socket issue by creating or linking 'mysqld.sock'.
• Skip the 'my.cnf' file if necessary.
