Overview

The /usr/local/cpanel/scripts/auto-adjust-mysql-limits script updates MySQL® configuration values for the following cPanel & WHM settings:

  • Allow cPanel & WHM to determine the best value for your MySQL open_files_limit configuration?
  • Allow cPanel & WHM to determine the best value for your MySQL max_allowed_packet configuration?
  • Allow cPanel & WHM to determine the best value for your MySQL innodb_buffer_pool_size configuration?

You can configure these settings in the SQL section of WHM’s Tweak Settings interface (WHM >> Home >> Server Configuration >> Tweak Settings).

This script runs when whenever you update the MySQL-related tweak settings and when you transfer or restore an account.
