MySQL主从复制“未知数据库”错误

Question

I'm trying to setup master-slave replication between 2 mysql servers on CentOS. Once setup if I create a database called 'fakeDB' on the master it creates it on the slave. Awesome! But if I then try to create a table on the master I get this error on the slave:

Last_Errno: 1049
Last_Error: Error 'Unknown database 'fakeDB'' on query. Default database: 'fakeDB'. Query: 'create table tmp (name varchar(100))'

But the database exists on the slave! So I then started over and created the database and tmp table on both servers. I reset everything and then tried to insert a row on the master. I then got this error on the slave:

Last_SQL_Errno: 1146
Last_SQL_Error: Error 'Table 'fakeDB.tmp' doesn't exist' on query. Default database: 'fakeDB'. Query: 'insert into tmp values ('asdf')'

But again that database exists and so does the table on both servers. I can access them manually. Here is the variables I set in the my.cnf file on both servers.

server-id = 1 #set as 2 for master
log_bin = /var/lib/mysql/mysql-bin.log
relay-log  = /var/lib/mysql/mysql-relay-bin.log
binlog_do_db = fakeDB

What am I doing wrong?

Ok. I figured it out. Turns out it was something stupid. I had this option set in my configuration file on the slave:

lower_case_table_names=1

So when I created the database on the master as fakeDB it created it on the slave as fakedb . So on the slave I can issue use fakeDB; and it works because the command is case insensitive but then the queries issued from the master weren't so insert into fakeDB.tmp failed because the database name is fakedb .
