You will be back later to view the mysql running status and backup status, and log on to mysql to view the master-slave synchronization status from the database.

Suddenly Slave_IO_Running: The status changes to NO

 

Solution.

First, execute

Stop slave;

 

View master Status of the master database

 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 specified12 13 mysql> flush logs;14 Query OK, 0 rows affected (0.11 sec)

Refresh binlog

Flush logs;

The refresh log will be + 1

For example, the File: mysql-bin.000113 above will become File: mysql-bin.000114

View master status again

 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

Then you do not need to operate the master and switch to the slave database.

Enter change master to MASTER_LOG_FILE = 'mysql-bin.000114 ', MASTER_LOG_POS = 120;

Run start slave;
