MySQL 8.0 Reference Manual  /  ...  /  Server Configuration Defaults

Pre-General Availability Draft: 2017-09-21

5.1.2 Server Configuration Defaults

The MySQL server has many operating parameters, which you can change at server startup using command-line options or configuration files (option files). It is also possible to change many parameters at runtime. For general instructions on setting parameters at startup or runtime, see Section 5.1.4, “Server Command Options”, and Section 5.1.5, “Server System Variables”.

On Windows, MySQL Installer interacts with the user and creates a file named my.ini in the base installation directory as the default option file.

Note

On Windows, the .ini or .cnf option file extension might not be displayed.

On any platform, after completing the installation process, you can edit the default option file at any time to modify the parameters used by the server. For example, to use a parameter setting in the file that is commented with a # character at the beginning of the line, remove the #, and modify the parameter value if necessary. To disable a setting, either add a # to the beginning of the line or remove it.

For additional information about option file format and syntax, see Section 4.2.6, “Using Option Files”.
