mysql主从不同步问题 Error_code: 1197
首先查看从的状态
mysql> show slave status \G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 10.120.141.228 Master_User: sys_repl Master_Port: 3306 Connect_Retry: 10 Master_Log_File: mysql-bin.000247 Read_Master_Log_Pos: 39320676 Relay_Log_File: mysqld-relay-bin.000064 Relay_Log_Pos: 213210879 Relay_Master_Log_File: mysql-bin.000242 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1197 Last_Error: Coordinator stopped because there were error(s) in the worker(s).

提示已经很明显了，让查看performance_schema.replication_applier_status_by_worker这个表看详细的问题
mysql> select * from performance_schema.replication_applier_status_by_worker\G *************************** 1. row *************************** CHANNEL_NAME: WORKER_ID: 1 THREAD_ID: NULL SERVICE_STATE: OFF LAST_SEEN_TRANSACTION: ANONYMOUS LAST_ERROR_NUMBER: 1197 LAST_ERROR_MESSAGE: Worker 1 failed executing transaction 'ANONYMOUS' at master log mysql-bin.000242, end_log_pos 347537149; Could not execute Delete_rows event on table pipeline.m_orderitem; Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage; increase this mysqld variable and try again, Error_code: 1197; handler error HA_ERR_RBR_LOGGING_FAILED; the event's master log mysql-bin.000242, end_log_pos 347537149 LAST_ERROR_TIMESTAMP: 2018-10-24 16:18:24
有些比较明显的问题系统会给出一些建议的解决方案，大多是跟着系统说得做就好了。

这样就OK了
