使用pt-online-schema-change 修復主從數據表數據不一致
step 1: 設置master的binlog_format爲row set global binlog_format=row;
step 2： 對比一下主從的test11 的某一條數據，並在slave上刪除該條數據
--master
mysql> select * from test11 where comment_id=20;
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
| comment_id | report_id | uid | content | dateline | status | client_ip | reply_uid | score |
+------------+-----------+-------+---------- -----+------------+--------+-----------------+-----------+-------+
| 20 | 134 | 48**7 | 感謝一下你的推薦哦 | 1301567128 | 0 | 113.234.154.150 | 0 | 0.000 |
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
1 row in set (0.00 sec)
mysql>
--slave
mysql> select * from test11 where comment_id=20;
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
| comment_id | report_id | uid | content | dateline | status | client_ip | reply_uid | score |
+------------+-----------+-------+---------- -----+------------+--------+-----------------+-----------+-------+
| 20 | 134 | 48**7 | 感謝一下你的推薦哦 | 1301567128 | 0 | 113.234.154.150 | 0 | 0.000 |
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
1 row in set (0.00 sec)
mysql>
mysql> delete from test11 where comment_id=20;
Query OK, 1 row affected (0.00 sec)
mysql> select * from test11 where comment_id=20;
Empty set (0.00 sec)
mysql>
step 3: 使用pt工具在master上執行 alter table test.test11 ENGINE=InnoDB
--master
pt-online-schema-change -S /home/jm/data/my6007/socket/mysqld.sock --alter='ENGINE=InnoDB' D=test,t=test11 --execute
...
Successfully altered `test`.`test11`.
step 4: 查看主從數據
--slave
mysql> select * from test11 where comment_id=20;
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
| comment_id | report_id | uid | content | dateline | status | client_ip | reply_uid | score |
+------------+-----------+-------+---------- -----+------------+--------+-----------------+-----------+-------+
| 20 | 134 | 48**7 | 感謝一下你的推薦哦 | 1301567128 | 0 | 113.234.154.150 | 0 | 0.000 |
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
1 row in set (0.00 sec)
mysql>
--master
mysql> select * from test11 where comment_id=20;
+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
| comment_id | report_id | uid | content | dateline | status | client_ip | reply_uid | score |
+------------+-----------+-------+---------- -----+------------+--------+-----------------+-----------+-------+

+------------+-----------+-------+-----------------+------------+--------+-----------------+-----------+-------+
1 row in set (0.00 sec)
