## | This is a base configuration file containing the most frequently used |
## | settings with reasonably defined default values for configuring and   |
## | tuning MySQL. Note that these settings can likely be further tuned in |
## | order to get optimum performance from MySQL based upon the database   |
## | configuration and hardware platform.                                  |
## |                                                                       |
## | For many deployments, the only variables which need to be modified    |
## | below are max-connections and innodb-buffer-pool-size.                |
