MySQL Error 3525: Security Table Access Failure
Description
This error indicates that the MySQL server process could not access or open its critical internal security system tables. These tables store essential user authentication, authorization, and role management data. It typically occurs during server startup or when security-related operations are attempted, preventing the database from functioning correctly.
Error Message
Failed to open the security system tables
Known Causes
4 known causesInsufficient File Permissions
The operating system user running the MySQL server process lacks the necessary read and write permissions for the files corresponding to the security system tables in the data directory.
Corrupted Security Tables
The internal security system tables (e.g., `mysql.user`, `mysql.db`) or their underlying data files have become corrupted, making them unreadable by the server.
Incorrect Data Directory
The MySQL server is configured with an incorrect `datadir` path, causing it to look for system tables in the wrong location where they do not exist or are inaccessible.
Underlying Storage Problems
Issues with the physical disk or storage system hosting the MySQL data directory prevent the server from accessing or opening the required table files.
