MySQL 1165: Error reading from file.

  1. Verify the MySQL error log for any additional error messages that can provide more context. You can find the error log location by running:


SHOW VARIABLES LIKE 'log_error';

  1. Check the file and directory permissions of the file mentioned in the error to ensure MySQL has read access. Use the command:


ls -l /path/to/problematic/file

  1. Confirm there is enough disk space on the drive where the MySQL data directory and the problematic file are located:


df -h

  1. Ensure the file mentioned in the error actually exists at the specified path. If not, you may need to restore it from a backup.



  1. If running in a replication setup, and the error relates to reading a binary log or relay log file, consider showing binary/relay log status:


SHOW BINARY LOGS;
SHOW RELAYLOG EVENTS;


  1. If the error persists and is related to a specific table, attempt to verify and repair the table using:


CHECK TABLE yourtablename;
REPAIR TABLE your
tablename;

  1. Restart the MySQL service to clear any temporary file-related issues that might have arisen during runtime:


sudo systemctl restart mysql

8. If the problem is related to not being able to read a file required for a MySQL upgrade or system table, consult the specific MySQL version upgrade documentation for troubleshooting steps related to your version.
