加粗的地方是我重点要解决的，此服务器为主服务器，我在从服务器上show slave status得到的 Slave_IO_Running和Slave_SQL_Running都是YES，真不知道哪里错了


------解决方案--------------------
slave的数据已经跟上master的数据了吗？主服务器重启的时候怎么会connecting to master，难道你这个主服务器又是某一台mysql服务器的从服务器？
------解决方案--------------------
主库上不允许从库访问 在主上开下这个用户的复制权限
------解决方案--------------------
可能是启动当时的网络环境不好，导致连接失败，然后记录了一个错误，随后又连上了，所以IO线程是YES。

主从看IO和SQL线程，都是YES，就行了。
------解决方案--------------------
你用的是mysql5.5的版本吧，这个版本不支持master这样的语法，看下这篇文章http://webteam.blog.51cto.com/863355/738310
