今天監控顯示mysql主從複製出錯了，資訊如下：

在mysql.cnf裡面有一句跳過經常出現的錯誤，但是還是報了1236錯誤

slave-skip-errors = 1062,1091,1396,1050,1060,1054,1146,1236

嘗試stop slave ； start slave 還是沒有恢複

然後就照著上面的錯誤提示更新pos點

mysql> stop slave;Query OK, 0 rows affected (0.01 sec)mysql> change master to master_log_file=‘master-bin.000774‘, master_log_pos=4;Query OK, 0 rows affected (0.12 sec)mysql> start slave;Query OK, 0 rows affected (0.00 sec)

然後查看狀態就恢複正常了，具體原因再慢慢分析,,,,,,,   

有時候還會報下面這個資訊

              Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: ‘could not find next log; the first event ‘mysql-bin.001891‘ at 897184977, the last event read from ‘./mysql-bin.001891‘ at 1109808979, the last byte read from ‘./mysql-bin.001891‘ at 1109808979.‘

上面這個錯誤嘗試stop slave ； start slave 就恢複了
