MySQL主从备份总是不成功

我先贴下我的代码
主 192.168.0.32  版本5.1
被 192.168.0.128 版本5.5主my.cnf 添加代码
log-bin=/var/log/mysql/updatelog
　　server-id = 1
　　binlog-do-db=KAPAI
　　binlog-ignore-db=mysql从my.cnf 添加代码
server-id=2
log-bin=mysql-bin
master-host=192.168.0.32
master-user=testback
master-password=testback
master-port=3306
replicate-do-db=KAPAI  #需要备份的数据库名
replicate-ignore-db=mysql #忽略的数据库
master-connect-retry=60 #如果从服务器发现主服务器断掉，重新连接的时间差(秒)
log-slave-updates #这个参数一定要加上，否则不会给更新的记录些到二进制文件里
slave-skip-errors #是跳过错误，继续执行复制操作
错误表现：

求大神们看下  网上搜的都是 说添加 CHANGE MASTER TO MASTER_HOST='192.168.0.32',MASTER_USER='testback',MASTER_PASSWORD='testback',MASTER_LOG_FILE='log-bin.000018',MASTER_LOG_POS=106;  这段 但是我已经添加无数次了我看到状态 Last_IO_Error: error connecting to master '[email protected]:3306' - retry-time: 60  retries: 86400 这个有错误 这个是连接不上的问题？？
