 5.6之前跳过失败事务命令:

mysql> set global sql_slave_skip_counter=1;  --指定跳过一个事务

 5.6版本GTID跳过失败事务操作步骤:

mysql> show slave status \G;

                Auto_Position: 1
1 row in set (0.00 sec)
 
因为该部署模式为主主复制,所以可以从出错的DB上查看slave状态,显示主库上3-5,而报错库只到1-3,所以,执行以下命令:
 
mysql> stop slave;
Query OK, 0 rows affected (0.08 sec)
 
mysql> set GTID_NEXT= 2d7ca199-4ad8-11e5-b592-080027f8dc35:3;
Query OK, 0 rows affected (0.00 sec)
 
mysql> begin;commit;
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
 
mysql> set gtid_next=AUTOMATIC;
Query OK, 0 rows affected (0.00 sec)
 
mysql> start slave;
Query OK, 0 rows affected (0.06 sec)
 
mysql> show slave status \G;   --查看是否有错,如果还没有跳过,则继续往下执行空事务跳过错误事务,直到SQL,IO进程均为yes即可
 
也可主库上查看binlog ,出错DB上会显示如下:
从库上:show slave status \G;   --查看exec_master_log_pos 从库上执行master日志的位置
 Exec_Master_Log_Pos: 763
 
到主库的binlog目录 :
     mysqlbinlog  slave-bin.000029 --start-position=763  进行next-gtid查看
