mysql主从同步时，由于意外的操作，可能会出现下面的错误：

Could not execute Update_rows event on table confluence.AO_92296B_AORECENTLY_VIEWED; Can’t find record in ‘AO_92296B_AORECENTLY_VIEWED’, Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event’s master log mysql-bin.000101, end_log_pos 711518695

或者

Coordinator stopped because there were error(s) in the worker(s). The most recent failure being: Worker 1 failed executing transaction ‘ANONYMOUS’ at source log mysql-bin.000003, end_log_pos 1271796. See error log and/or performance_schema.replication_applier_status_by_worker table for more details about this failure or others, if any

此时需要查看end_log_pos对应的是什么数据操作，就需要把binlog二进制文件解释成可读的文件。

使用 mysqlbinlog 命令可以解释binlog文件，查询mysql数据库所有数据包括表和字段的操作记录。

binlog文件保存在mysql的data目录中。

mysqlbinlog命令保存的mysql的bin目录中。

进入mysql/bin目录，执行

./mysqlbinlog --no-defaults --base64-output=decode-rows -v /opt/mysql/data/binlog.000003 --result-file=binlog0003.sql

–no-defaults 参数是为了避免出现错误：

unknown variable ‘default-character-set=utf8mb4’

-v 参数可以解释出具体的sql：

找到错误信息里对应的end_log_pos，即可找到具体的sql。
