how to make replication without taking master down

i have a production mysql server which can't be taken down even for one sec. i know the basic step to make a replication, but i have trouble making a consistent snapshot without taking down mysql server or do a READ LOCK.
i dump my master DB with the following command(it uses innodb): mysqldump -q -A -F --single-transaction --no-autocommit
--master-data=1 > test.sql

then rsync the test.sql to slave server,import it: mysql < test.sql

then i tried to "start slave",soon after the slave try to catch up with master,it runs into an duplicated key error. I've also tried to dump the DB with "-B AAA BBB" instead of "-A",but it still ran into the same error.
If I bring down the master server and do the same thing,i dont get any error and sucessfully have the slave catch up with my master.

does any one have idea how to achieve the goal? thx a lot!
