binlog_checksum
Introduced5.6.2System VariableNamebinlog_checksumVariable ScopeGlobalDynamic VariableYesPermitted Values (<= 5.6.5)TypestringDefaultNONEValid ValuesNONECRC32Permitted Values (>= 5.6.6)TypestringDefaultCRC32Valid ValuesNONECRC32When enabled, this variable causes the master to write a checksum for each event in the binary log. binlog_checksum supports the valuesNONE (disabled) and CRC32. The default is CRC32 as of MySQL 5.6.6, NONE before that.
When binlog_checksum is disabled (value NONE), the server verifies that it is writing only complete events to the binary log by writing and checking the event length (rather than a checksum) for each event.
Changing the value of this variable causes the binary log to be rotated; checksums are always written to an entire binary log file, and never to only part of one.
This variable was added in MySQL 5.6.2.
In MySQL 5.6.6 and later, setting this variable on the master to a value unrecognized by the slave causes the slave to set its own binlog_checksum value to NONE, and to stop replication with an error. (Bug #13553750, Bug #61096) If backward compatibility with older slaves is a concern, you may want to set the value explicitly to NONE.
通过官网得知，MySQL版本5.6.5之前跟5.6.5之后版本binlog_checksum默认的值不同。
所以在主服务器的my.cnf添加下面代码
[mysqld]
binlog_checksum=none
在主服务器上重启MySQL
