MySQL5.6 GTID模式下同步复制报错不能跳过的解决方法

数据库版本：

mysql> select version();

+------------+
| version() |
+------------+
| 5.6.10-log |
+------------+
1 row in set (0.02 sec)

同步复制信息：

mysql> show slave status\g;

提示主键冲突，由于是测试机，于是我直接跳过，

mysql> set global sql_slave_skip_counter=1;

error 1858 (hy000): sql_slave_skip_counter can not be set when the server is running with gtid_mode = on.
instead, for each transaction that you want to skip, generate an empty transaction with the same gtid as the transaction

提示：由于运行在gtid模式，所以不支持sql_slave_skip_counter语法，如果你想跳过，就必须把事务id设置为空值。
看来只能用这个方法了。

mysql> show global variables like '%gtid%';

+--------------------------+--------------------------------------------+
| variable_name | value |
+--------------------------+--------------------------------------------+
| enforce_gtid_consistency | on |
| gtid_executed | cf716fda-74e2-11e2-b7b7-000c290a6b8f:1-140 |
| gtid_mode | on |

| gtid_purged | cf716fda-74e2-11e2-b7b7-000c290a6b8f:1-140 |
+--------------------------+--------------------------------------------+
5 rows in set (0.04 sec)

mysql> set global gtid_executed='';
error 1238 (hy000): variable 'gtid_executed' is a read only variable
mysql>
mysql> set global gtid_purged='';

error 1840 (hy000): gtid_purged can only be set when gtid_executed is empty.
郁闷，直接设置还不行。

查看了手册，需要执行reset master才可以（注：在从上执行啊，千万别在主上）。

mysql> reset master;
query ok, 0 rows affected (0.16 sec)

mysql> reset slave;
error 1198 (hy000): this operation cannot be performed with a running slave; run stop slave first
mysql> stop slave;
query ok, 0 rows affected (0.08 sec)

mysql> reset slave;
query ok, 0 rows affected (0.16 sec)

执行reset slave的目的是清空master.info和relay-log.info，以便后面重新change master to主从复制。
还记得刚才的gtid_purged那个点吗，只需重新设置下一个点即可。

下面是步骤：

mysql> show global variables like '%gtid%';
+--------------------------+-------+
| variable_name | value |
+--------------------------+-------+
| enforce_gtid_consistency | on |
| gtid_executed | |
| gtid_mode | on |
| gtid_owned | |
| gtid_purged | |
+--------------------------+-------+
5 rows in set (0.06 sec)

mysql> set global gtid_purged='cf716fda-74e2-11e2-b7b7-000c290a6b8f:1-141';
query ok, 0 rows affected (0.16 sec)

mysql> change master to master_host='192.168.8.25',master_user='repl',master_password='repl'
,master_auto_position = 1;
query ok, 0 rows affected, 2 warnings (0.32 sec)

mysql> start slave;
query ok, 0 rows affected (0.13 sec)

mysql> show slave status\g;

### 看，这里的报错信息已经不一样了，按照这种方法，重复执行，直到同步复制正常。

mysql> stop slave;
query ok, 0 rows affected (0.07 sec)

mysql> reset master;
query ok, 0 rows affected (0.17 sec)

mysql> reset slave;

mysql> set global gtid_purged='cf716fda-74e2-11e2-b7b7-000c290a6b8f:1-151';
query ok, 0 rows affected (0.13 sec)

mysql> change master to master_host='192.168.8.25',master_user='repl',master_password='repl'
,master_auto_position = 1;
query ok, 0 rows affected, 2 warnings (0.33 sec)

呵呵，总算是解决好了，真麻烦啊。如果大家有更好、更方便的解决方法，也给我回帖哦，谢谢。
