Duda con SET GLOBAL log_bin_trust_function_creators = 1;

[huesos52]

To relax the preceding conditions on function creation (that you must have the SUPER privilege and that a function must be declared deterministic or to not modify data), set the global log_bin_trust_function_creators system variable to 1. By default, this variable has a value of 0, but you can change it like this:

mysql> SET GLOBAL log_bin_trust_function_creators = 1;
You can also set this variable by using the --log-bin-trust-function-creators=1 option when starting the server.

If binary logging is not enabled, log_bin_trust_function_creators does not apply. SUPER is not required for function creation unless, as described previously, the DEFINER value in the function definition requires it.

Al momento de iniciar el servidor puedes levantarla y quedará por defecto.
