MySQL Error 1018: Failed to Read Directory
Description
MySQL Error 1018 indicates that the MySQL server was unable to read the contents of a specified directory. This typically occurs when the server attempts to access data files, temporary files, or other system-related directories crucial for its operation, but encounters an access restriction or an invalid path.
Error Message
Can't read dir of '%s' (errno: %d - %s)
Known Causes
4 known causesInsufficient Directory Permissions
The operating system user running the MySQL process lacks the necessary read and execute permissions for the specified directory or its parent directories.
Missing or Invalid Directory Path
The directory MySQL is trying to access does not exist at the specified path, has been moved, or is somehow unreadable/corrupt.
Incorrect MySQL Configuration
MySQL's configuration files (e.g., `my.cnf` or `my.ini`) specify an incorrect or inaccessible path for data, temporary, or plugin directories.
Security Policy Restrictions
Operating system security modules like SELinux or AppArmor are preventing MySQL from accessing the directory, even if file system permissions seem correct.
