我要做个mysql 双机热备，主服务器配置如下：
server-id=1
log-bin="C:/Program Files/MySQL/MySQL Server 5.1/mysqllog"
binlog-do-db=project_gis配置完成了能正常启动，日志也生成了。从服务器配置如下：
server-id=2
master-host=192.168.0.101
master-user=dbback
master-passWord=dbback
master-port=3306
master-connect-retry=60
replicate-do-db=projectdbback用户我都授权了，数据库版本都是5.1.30
但是我的从服务器现在起不来，不知道为什么，删除掉上面的配置就好了。
