MySQL Error: Missing Socket File `/var/run/mysqld/mysqld.sock` - How to Reconnect?

Error Connecting to MySQL: Missing Socket File

When attempting to run mysqld_safe --skip-grant-tables to reset a MySQL password, some users encounter an error indicating that the socket file /var/run/mysqld/mysqld.sock is missing. This prevents the connection to the local MySQL server, resulting in failure to reset the password.

The error message reads:

error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'

Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

To resolve this issue, follow these steps:

1. Verify MySQL Status: Ensure MySQL is running by using the command:

sudo service mysql status

2. Create Socket File: If the socket file is missing, manually create it using the command:

sudo touch /var/run/mysqld/mysqld.sock

3. Set File Permissions: Grant necessary permissions to the socket file:

sudo chmod 777 /var/run/mysqld/mysqld.sock

4. Restart MySQL: Restart the MySQL service to recognize the new socket file:

sudo service mysql restart

5. Reconnect: Once MySQL is restarted, try connecting again using the -u root flag to provide root user authentication.

If the issue persists, consider additional troubleshooting steps such as checking firewall settings, verifying database configurations, or seeking professional assistance.
