We are thinking how we will run the indexing using command line and which command we will use to run this.
Now here we are describing the command:
If we need to do whole index management in the site we will run the following command in project
In root magento directory
php bin/magento indexer:reindex
in root/bin directory
php magento indexer:reindex
To get the index name to run index one by one first write below command to get info
in magento root directory
php bin/magento indexer:info
To run single reindexing command
php bin/magento indexer:reindex indexer_name
indexer name which we received name from indexer:info
Execute the command from command line and be happy. Indexing will work perfectly.
