[align=left]问题所在：[/align]
[align=left]1.服务器进行授权访问权限问题，解决方法：[/align]
[align=left] mysql> grant replication slave on *.* to slave@10.11.5.170 identified by ‘123‘；[/align]
[align=left]2.master_log_file和binlog_log_pos不一致，解决方法：[/align]
[align=left]在主服务器上show master status;看下日志文件名和位置[/align]
[align=left]在从服务器上slave stop;[/align]
[align=left] mysql> stop slave;[/align]
mysql> change master to master_log_file='mysql-bin.000008',master_log_pos=98;

mysql> start slave;
3.互为主从的服务器有一台slave未正常启动，解决方法：
change master to master_host='10.11.5.170';
4.两台服务器是否在同一网段，iptables是否把3306端口关了。本文出自 “tonylinux” 博客，请务必保留此出处http://tonylinux.blog.51cto.com/2268300/874761
