内容图文
master上删除某个数据表的某一行，而该行在slave上并不存在，则slave上的复制过程会出错。
MySQL的log文件中发现如下错误信息：
2017-08-15T04:52:19.529509Z 13 [ERROR] Slave SQL for channel ‘‘: Could not execute Delete_rows event on table test.test; Can‘t find record in ‘test‘, Error_code: 1032; handler error HA_ERR_END_OF_FILE; the event‘s master log mysql-bin.000007, end_log_pos 1958, Error_code: 1032
2017-08-15T04:52:19.529575Z 13 [Warning] Slave: Can‘t find record in ‘test‘ Error_code: 1032
2017-08-15T04:52:19.529588Z 13 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log ‘mysql-bin.000007‘ position 1732
(2)重现问题场景。
(a)在slave上删除数据表test的某一行数据。
mysql> delete from test where name2=‘001‘;
Query OK, 1 row affected (0.07 sec)
mysql> select * from test;
+-------+
| name2 |
+-------+
| 002 |
| 003 |
+-------+
2 rows in set (0.00 sec)
(b)在master上删除数据表test的该行数据。
mysql> select * from test;
+-------+
| name2 |
+-------+
| 001 |
| 002 |
| 003 |
+-------+
3 rows in set (0.00 sec)
mysql> delete from test where name2=‘001‘;
Query OK, 1 row affected (0.02 sec)
mysql> select * from test;
+-------+
| name2 |
+-------+
| 002 |
| 003 |
+-------+
2 rows in set (0.00 sec)
删除后再插入新的数据。
mysql> insert into test (name2) values( ‘004‘ );
Query OK, 1 row affected (0.02 sec)
mysql> select * from test;
+-------+
| name2 |
+-------+
| 002 |
| 003 |
| 004 |
+-------+
3 rows in set (0.00 sec)
(c)查看slave上的数据。
mysql> select * from test;
+-------+
| name2 |
+-------+
| 002 |
| 003 |
+-------+
2 rows in set (0.00 sec)
可以看到slave中并没有发现master上新插入的行’004’。
(d)查看slave的复制状态。
mysql> show slave status\G

可以看到，出现了错误代码未1032的错误信息，删除的行不存在。
(3)解决办法。
由于导致出错的原因是slave中不存在待删除的行，此时可以直接忽略该错误。
mysql> stop slave;
Query OK, 0 rows affected (0.01 sec)
mysql> set global sql_slave_skip_counter=1;
Query OK, 0 rows affected (0.00 sec)
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
注意：在使用基于GTID的复制(GTID_MODE = ON)时，不能使用sql_slave_skip_counter的方法来忽略错误；而是应该使用reset master重置mysql.gtid_executed数据表。
此时查看复制状态：
mysql> show slave status\G
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event
Master_Host: mysql101.coe2coe.me
Master_User: repl

已经恢复到正常状态了。
查看数据表的数据，也可以看到跟master中的数据完全一样了，即可以看到新增的行。
mysql> select * from test;
+-------+
| name2 |
+-------+
| 002 |
| 003 |
| 004 |
+-------+
3 rows in set (0.00 sec)
至此，删除不存在的行导致的复制错误，已经成功得到解决。
