mysql5.5双节点互为主从遇到的问题

Question

问题:
当我在一个节点上
create database php_db;
show databases;
这个时候是有php_db的
但是slave stop;
start slave;
flush privileges;
show databases;
这个php_db就没有了
跑到对面节点去了
究竟是哪里出了问题呢?!配置情况如下
节点一(在这个节点执行的创建php_db命令)

Answer 2

mysqlbinlog解析一下binlog和relaybinlog就知道原因了

Answer 3

问题解决了
方法是清理掉日志
就可以正常同步了
无论是创建database还是table还是dml操作
都可以
