MySQL 3225

This error occurs when an invalid character is used in the host name for the MySQL audit log. MySQL 3225 indicates that the host name contains an invalid character.

How It Affects Your App

This error indicates that the host name used for the audit log contains an invalid character. This can prevent the application from properly logging audit events, which can lead to a lack of visibility into the application's activity. This can make it difficult to troubleshoot issues, identify security risks, and ensure compliance with regulations. Additionally, it can lead to data loss or corruption if the application is unable to properly log changes to the database.

How To Fix

1. Check the error log for the MySQL 3225 error:

SELECT query_text FROM pg_stat_activity WHERE state = ‘error’;

2. Check the MySQL configuration file for any misconfigurations:

$ cat /etc/mysql/my.cnf

3. Check the MySQL process list for any suspicious activity:

$ mysqladmin -u root -p processlist

4. Check the MySQL user table for any suspicious users:

$ mysql -u root -p -e "SELECT * FROM mysql.user;"

5. Check the MySQL grant tables for any suspicious grants:

$ mysql -u root -p -e "SELECT * FROM mysql.db;"

6. Check the MySQL system variables for any misconfigurations:

SELECT query_text FROM pg_stat_activity WHERE state = ‘error’;

7. Check the MySQL system status for any misconfigurations:

$ mysql -u root -p -e "SHOW STATUS;"
