在Master節點(diǎn)上查看二進(jìn)制日志的位置
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)

查看Master節點(diǎn)的二進(jìn)制日志
mysql> show master logs;
+------------------+-----------+
| Log_name         | File_size |
+------------------+-----------+
| mysql-bin.000010 |      3780 |
| mysql-bin.000011 |      1734 |
+------------------+-----------+
2 rows in set (0.06 sec)

查看Slave節點(diǎn)的二進(jìn)制日志
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(diǎn)上刪除了二進(jìn)制日志，導致Slave節點(diǎn)的IO線(xiàn)程獲取不到指定的二進(jìn)制日志

在Master節點(diǎn)上設置了自動(dòng)刪除二進(jìn)制日志的參數，5天后會(huì )自動(dòng)刪除二進(jìn)制日志；而Slave節點(diǎn)所在的數據庫一直沒(méi)有啟動(dòng)，再次啟動(dòng)時(shí)IO線(xiàn)程獲取不到Master節點(diǎn)的二進(jìn)制日志
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(jìn)制日志備份，否則需要重建Slave節點(diǎn)
