Solve the main from a backup Slave_SQL_Running: No

mysql> show slave status\G

         .......
             Relay_Log_File: localhost-relay-bin.000535
              Relay_Log_Pos: 21795072
      Relay_Master_Log_File: localhost-bin.000094
           Slave_IO_Running: Yes
          Slave_SQL_Running: No
            Replicate_Do_DB: 
        Replicate_Ignore_DB: 
      ......

 

A solution,

Slave_SQL_Running: No
1. program may be a write operation on the slave

2. After the slave machine may be restarted, transaction rollback caused.

Is usually caused by transaction rollback:
Solution:

mysql> stop slave ;
mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;
mysql> start slave ;

 

Solution II (recommended)

First, the service stopped Slave: slave stop
to the primary server host status view:
Record File Position and the corresponding value

Into the master

mysql> show master status;
+----------------------+----------+--------------+------------------+
| File                 | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+----------------------+----------+--------------+------------------+
| localhost-bin.000094 | 33622483 |              |                  | 
+----------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

 

Then the slave server to perform a manual synchronization:


mysql> change master to 
> master_host='master_ip',
> master_user='user', 
> master_password='pwd', 
> master_port=3306, 
> master_log_file=localhost-bin.000094', 
> master_log_pos=33622483 ;
1 row in set (0.00 sec)
mysql> start slave ;
1 row in set (0.00 sec)

start slave

 

View from the state library

mysql> show slave status

            Master_Log_File: localhost-bin.000094
        Read_Master_Log_Pos: 33768775
             Relay_Log_File: localhost-relay-bin.000537
              Relay_Log_Pos: 1094034
      Relay_Master_Log_File: localhost-bin.000094
           Slave_IO_Running: Yes
          Slave_SQL_Running: Yes
            Replicate_Do_DB:

CHANGE MASTER TO master_host = '192.168.0.61',
master_port = 3306,
master_user = 'root',
master_password = 'root',
master_log_file = 'mysql-bin.000014',
master_log_pos = 489;
