Environment Variables

This section lists all the erwironment variables that are used directly or indirectly by MySQL. Most of

these can also be found in other places in this manuał.

Notę that any options on the command linę take precedence over values specified in option files

and environment variables, and values in option files take precedence

over values in environment

variables.

In many cases, it is preferable to use an option file instead of environment variables to modify the

behavior of MySQL. See Section 4.2.3.3, “Using Option Files”.
