年后回來查看mysql運行狀況與備份情況，登錄mysql從庫查看主從同步狀態

57 1 row in set (0.00 sec)
58 
59 ERROR: 
60 No query specified

突然之間Slave_IO_Running: 狀態變成NO了

解決方法。

首先在從庫上執行

stop slave;

查看主庫master狀態

 1 mysql> show master status\G;
 2 *************************** 1. row ***************************
 3              File: mysql-bin.000113
 4          Position: 276925387
 5      Binlog_Do_DB: 
 6  Binlog_Ignore_DB: 
 7 Executed_Gtid_Set: 
 8 1 row in set (0.00 sec)
 9 
10 ERROR: 
11 No query specified
12 
13 mysql> flush logs;
14 Query OK, 0 rows affected (0.11 sec)

刷新binlog日志

flush logs;

刷新后的日志會+1

例如上面的 File: mysql-bin.000113 會變成 File: mysql-bin.000114

再次查看master狀態

 1 mysql> show master status\G;
 2 *************************** 1. row ***************************
 3              File: mysql-bin.000114
 4          Position: 120
 5      Binlog_Do_DB: 
 6  Binlog_Ignore_DB: 
 7 Executed_Gtid_Set: 
 8 1 row in set (0.00 sec)
 9 
10 ERROR: 
11 No query specified

然后就不需要在操作master，切換到從庫

輸入CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000114',MASTER_LOG_POS=120;

執行start slave;

查看從庫狀態

 1 mysql> show slave status\G;
