在Master節點上檢視二進位制日誌的位置
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000011 |     1734 |              |                  |                   |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)

檢視Master節點的二進位制日誌
mysql> show master logs;
+------------------+-----------+
| Log_name         | File_size |
+------------------+-----------+
| mysql-bin.000010 |      3780 |
| mysql-bin.000011 |      1734 |
+------------------+-----------+
2 rows in set (0.06 sec)

檢視Slave節點的二進位制日誌
mysql> show binary logs;
+------------------+-----------+
| Log_name         | File_size |
+------------------+-----------+
| mysql-bin.000008 |       154 |
| mysql-bin.000009 |       154 |
+------------------+-----------+
2 rows in set (0.02 sec)

報錯原因:
在Master節點上刪除了二進位制日誌,導致Slave節點的IO執行緒獲取不到指定的二進位制日誌

在Master節點上設定了自動刪除二進位制日誌的引數,5天后會自動刪除二進位制日誌;而Slave節點所在的資料庫一直沒有啟動,再次啟動時IO執行緒獲取不到Master節點的二進位制日誌
mysql> show variables like '%expire%';
+--------------------------------+-------+
| Variable_name                  | Value |
+--------------------------------+-------+
| disconnect_on_expired_password | ON    |
| expire_logs_days               | 5     |
+--------------------------------+-------+
2 rows in set (0.02 sec)

解決方法:
除非主庫有二進位制日誌備份,否則需要重建Slave節點
