Magento “Indexers are Invalid”

After installing Magento, you have to take care of the “Indexers are invalid” problems.

To reindex in magento 2, go to the CLI and then the root folder of your magento installation and run the below command :

php bin/magento indexer:reindex

This will re-index all components of Magento
