Question

If I restart the mysql server, it changes the value to default value automatically.

mysql> show global variables like 'log_bin_trust_function_creators';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| log_bin_trust_function_creators | OFF   |
+---------------------------------+-------+
1 row in set (0.00 sec)

mysql> SET GLOBAL log_bin_trust_function_creators = ON;
Query OK, 0 rows affected (0.00 sec)

I would like to make this function ON no matter what happen.

Is there way to make it the my value to default value?

Answer 1

Specify the log-bin-trust-function-creators option in an option file (or use the --log-bin-trust-function-creators argument to mysqld on the command-line if you prefer).
