Question

几周之后，我们的reindex将不再起作用并因以下错误而崩溃：

我尝试过的事情：

截断所有catalog_category_flat_store_＃（1-40）表
截断所有catalog_product_flat_＃（1-40）表
尝试删除约束的其他地方。
在apache关闭的时候跑完Reindexer。

奇怪的是，“没有索引器运行”时，“产品价格”索引的状态仍为“正在处理”。当我尝试删除var / locks中的锁定文件时，它们会立即再次生成，就像还有一些东西试图索引一样，但事实并非如此。

任何帮助都会受到赞赏，因为我们在这里空白了！

Answer 1

catalog_product_index_eav表有一个名为

的外键约束

FK_CAT_PRD_IDX_EAV_ENTT_ID_CAT_PRD_ENTT_ENTT_ID

查看此表的定义

CREATE TABLE `catalog_product_index_eav` (
  `entity_id` int(10) unsigned NOT NULL DEFAULT '0' COMMENT 'Entity ID',
  `attribute_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Attribute ID',
  `store_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Store ID',
  `value` int(10) unsigned NOT NULL DEFAULT '0' COMMENT 'Value',
  PRIMARY KEY (`entity_id`,`attribute_id`,`store_id`,`value`),
  KEY `IDX_CATALOG_PRODUCT_INDEX_EAV_ENTITY_ID` (`entity_id`),
  KEY `IDX_CATALOG_PRODUCT_INDEX_EAV_ATTRIBUTE_ID` (`attribute_id`),
  KEY `IDX_CATALOG_PRODUCT_INDEX_EAV_STORE_ID` (`store_id`),
  KEY `IDX_CATALOG_PRODUCT_INDEX_EAV_VALUE` (`value`),
  CONSTRAINT `FK_CATALOG_PRODUCT_INDEX_EAV_STORE_ID_CORE_STORE_STORE_ID` FOREIGN KEY (`store_id`) REFERENCES `core_store` (`store_id`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `FK_CAT_PRD_IDX_EAV_ATTR_ID_EAV_ATTR_ATTR_ID` FOREIGN KEY (`attribute_id`) REFERENCES `eav_attribute` (`attribute_id`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `FK_CAT_PRD_IDX_EAV_ENTT_ID_CAT_PRD_ENTT_ENTT_ID` FOREIGN KEY (`entity_id`) REFERENCES `catalog_product_entity` (`entity_id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Catalog Product EAV Index Table';

我们可以看到外键定义是

CONSTRAINT `FK_CAT_PRD_IDX_EAV_ENTT_ID_CAT_PRD_ENTT_ENTT_ID` 
FOREIGN KEY (`entity_id`) 
REFERENCES `catalog_product_entity` (`entity_id`) 
ON DELETE CASCADE ON UPDATE CASCADE

这意味着对于entity_id中的每个catalog_product_index_eav行，entity_id中需要有相同的catalog_product_entity值。

您的问题的根源是出于某种原因（无论是网络扩展，是从互联网上随机输入SQL导致的错误，还是使用禁用的索引执行数据更新），Magento的索引尝试更新catalog_product_index_eav中的数据这违反了这条规则。下一步是确定Magento正在做什么，以便您可以修复数据。

如果我们查看你的调用堆栈，这看起来是一个开始调试的好地方

#10 app/code/core/Mage/Catalog/Model/Resource/Product/Indexer/Eav/Abstract.php(54): 
Mage_Index_Model_Resource_Abstract->syncData()

跳转到该源文件，我们看到以下代码

public function syncData()
{
    $this->beginTransaction();
    try {
        /**
         * Can't use truncate because of transaction
         */
        $this->_getWriteAdapter()->delete($this->getMainTable());
        $this->insertFromTable($this->getIdxTable(), $this->getMainTable(), false);
        $this->commit();
    } catch (Exception $e) {
        $this->rollBack();
        throw $e;
    }
    return $this;
}

作为索引过程的一部分，Magento尝试将数据从“索引表”（getIdxTable）同步到“源”（getMainTable）表。

public function insertFromTable($sourceTable, $destTable, $readToIndex = true)
{
    //...
}

对于此特定索引，索引表为catalog_product_index_eav_idx，源表为catalog_product_index_eav。

注意：请注意您的术语，这些内容令人困惑。 “源”表是我们要复制的表。（我相信它被称为源表，因为它是普通Magento系统在需要信息时会查询的“源”）

因此，Magento正在尝试将catalog_product_index_eav_idx中的一行同步到表catalog_product_index_eav。但是，这会导致前面提到的外键错误。这导致我们得出两个可能的结论

catalog_product_index_eav_idx entity_id中不存在catalog_product_entity行。{/ p>
catalog_product_index_eav表（通过以前关闭索引检查的操作）entity_id中不存在的catalog_product_entity行。

因此，您的任务是确定catalog_product_index_eav中catalog_product_index_eav_idx和catalog_product_entity中哪些entity_id行不存在，并手动删除所述行（来自catalog_product_index_eav和catalog_product_index_eav_idx）。

如果是我，并且我的catalog_product_entity表不是太大，我会从以下查询开始（这些是未经测试的，因为我没有任何带有上述无效数据状态的Magento表）

SELECT * 
FROM catalog_product_index_eav_idx 
WHERE NOT (entity_id IN (SELECT entity_id from catalog_product_entity));

SELECT * FROM catalog_product_index_eav 
WHERE NOT (entity_id IN (SELECT entity_id from catalog_product_entity));
