070514 18:07:28 [Warning] No argument was provided to --log-bin, and --log-bin-index was not used; so replication may break when this MySQL server acts as a master and has his hostname changed!! Please use '--log-bin=/usr/local/mysql-max-5.1-bk-20060217/var/flute-bin' to avoid this problem.
mysqld: File '/usr/local/mysql-max-5.1-bk-20060217/var/flute-bin.index' not found (Errcode: 13)
