Change the output database

[GooseSteps]

hello，
I want to change the output database in the barnyard2.conf。
so,The host changed to an 192.168.2.92 instead of localhost, like this: output database: log, mysql, user=snort password=123 dbname=snort host=192.168.2.92 sensor name=sensor01
but snort prompt a warning about the database connection.
Is my idea wrong or there are other ways？
thank you
