In Magento there is folder with name “shell” in this folder you will find file with name “indexer.php” this is shell script for reindexing. You will ask yourself how to call this script, and take a look on my examples below and everything will be clear.
First of all you need to have access to linux commnad line or shell, and then go to your “MAGENTO_ROOT_FOLDER/shell“.
Our first example is how to get help from “indexer.php” script, you need to execute next comand “php -f indexer.php help” and you will get response as in example below.
$ php -f indexer.php help
--status <indexer> Show Indexer(s) Status
--mode <indexer> Show Indexer(s) Index Mode
--mode-realtime <indexer> Set index mode type "Update on Save"
--mode-manual <indexer> Set index mode type "Manual Update"
--reindex <indexer> Reindex Data
info Show allowed indexers
reindexall Reindex Data by all indexers
help This help
<indexer> Comma separated indexer codes or value "all" for all indexersYou can see that you can make reindexall but I don’t recommend that you execute full reindex in one step, beacuse you can cause MySql/Server overload. Reindexall calls 8 indexers in a row and process of reindexing can cause database LOCK on some database tables.
I recommend that you execute one by one indexer. Your process will be faster and load of database will be smaller.
In Magento there are 8 indexers, you can get list of indexers if you call next command: php -f indexer.php info
exemple:
$ php -f indexer.php info
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
For example if you want to reindex “catalog_url” you need to execute next command: php -f indexer.php — -reindex catalog_url
example:
$ php -f indexer.php -- -reindex catalog_url
Catalog URL Rewrites index was rebuilt successfully
I recommend that you use indexer from shell because this process isn’t executing over web server/Apache and makes smaller impact on server resources.
One note: I had problem with php memory limit, error message: “Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 88 bytes)“. I increased memory size to 256MB, I added next statement on beginning of script: ini_set(‘memory_limit’, ‘256M’); .
