Magento 1.6.2无法重新索引产品平面数据

Question

我们的magento 1.6.2无法重新索引产品平面数据.它有时也会显示"重建索引过程出现问题".

我从其他用户的经验中尝试了很多解决方案.没有结果.我们进口散装产品,但我们不确定这是重新索引问题的原因.

什么是理想的解决方案？

这是我在shell中使用的命令:

php /usr/local/lsws/fcgi-bin/lsphp5 /home/user/domains/my domain../public_html/shell/indexer.php 

这是来自exception.log的错误

在Magento中重新索引错误可能有很多原因,所以我担心永远不会有一个涵盖所有可能错误的"理想"解决方案.

由于您发布了非技术性错误消息,我猜您已尝试使用管理员后端重新索引产品平面数据,并在那里看到错误消息.

我建议再次尝试重新索引,但使用shell/indexer.php这个时间:

/usr/bin/php -f /abs/path/to/shell/indexer.php -- --reindex catalog_product_flat

这样,如果重建索引失败,您将获得更有意义的技术错误消息.

这是一个列表,显示了用于哪个索引的参数:

catalog_product_attribute     Product Attributes
catalog_product_price         Product Prices
catalog_url                   Catalog URL Rewrites
catalog_product_flat          Product Flat Data
catalog_category_flat         Category Flat Data
catalog_category_product      Category Products
catalogsearch_fulltext        Catalog Search Index
cataloginventory_stock        Stock Status
tag_summary                   Tag Aggregation Data

UPDATE

您添加到帖子中的例外情况告诉我们之间的参照完整性

catalog_product_flat_4.entity_id

和

catalog_product_entity.entity_id

被发现被腐败了.

通常这意味着某些记录包含null字段中的字段catalog_product_entity.entity_id,其中它们应包含现有的entity_ids.

在尝试解决此问题之前,请先备份您的数据库.

现在,要查找损坏的记录,请使用以下命令查询数据库:

SELECT
    a.entity_id
FROM
    catalog_product_flat_4 AS a
LEFT JOIN
    catalog_product_entity AS b ON a.entity_id = b.entity_id
WHERE
    ISNULL(b.entity_id)

在entity_id此查询发现s为entity_idS IN的表catalog_product_flat_4,这已损坏,需要被删除.

删除相应的记录catalog_product_flat_4,然后再次尝试重新编制索引.
