MYSQL主从同步数据库版本不一致问题

原文链接： https://blog.csdn.net/czh500

主库：5.6
从库：5.5

报错： Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: ‘Slave can not handle replication events with the checksum that master is configured to log; the first event ‘mysql-bin.000001’ at 451, the last event read from ‘./mysql-bin.000001’ at 451, the last byte read from ‘./mysql-bin.000001’ at 120.’

主库：
set global binlog_checksum='NONE';
show variables like '%checksum%';
查看之后重新配置从库连接主库，问题得以解决。

ps:这样的话每次重启数据库需要重新输入命令。
也可以在my.cnf中加入binlog_checksum=none
