log_bin_trust_function_creators生产中参数设置？

log_bin_trust_function_creators主从的生产中大家如何环境设置的；

在MySQL主从复制机器的master的数据库中创建function，报出如下错误：
　　Error Code: 1418. This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you might want to use the less safe log_bin_trust_function_creators variable)

是在my.cnf中配置的是1吗？？
