I couldn't find the way to do reindexing in mass actions on magento 2.

Seems like you need to run it from cronjob. Is there an alternative way to reindex data in magento 2 from backend or command line just like it used to be in Magento 1.x (php shell/indexer.php -reindexall) ?

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

Run this command in your CLI

php bin/magento indexer:reindex

and if you want to reindex only one indexer then write following command:

php bin/magento indexer:reindex indexer_name.

where indexer_name can be found by typing following command :

php bin/magento indexer:info

Here is how you can get things done using Magento 2 CLI indexing commands

Get into your Magento CLI command file available in Magento/bin directory cd magento_folder/bin and run your command directly using Magento in terminal or putty.

Here is how it will work for indexing in Magento 2

##How to check the status of indexer##

The following command will get you the status of all the indexers whether indexing is required or ready.

php bin/magento indexer:status

You can also check the status of individual indexer: let's say I want to check the status of catalog_category_product

php bin/magento indexer:status catalog_category_product

Sometimes to make it easy, you may want to re-index directly from the admin without involving cron (especially if you haven't setup your cron jobs and the site is still in development). In such cases, you can use the free extension Admin Reindex [M2] which allows you to reindex from the admin.

You can re-index by using two different methods.

1- Re-Index from Admin Panel enter image description here

To do so-

Go to System > Tools > Index Management

Select the checkbox next to each type of Indexer to change

Select Indexing Mode from the Acton Dropdown Click Submit

2- Re-Index Using CLI (Command Line Interface)

Run the following Command in your CLI

Bin/magento indexer : reindex [indexer]

To view the list of Indexers-

Run the following Command-

bin/magento indexer : info

Magento 2 reindex using command line SSH:
php bin/magento indexer:reset && php bin/magento indexer:reindex

Note:
For performance reasons, Magento recommends that you set all indexers to run on "Update by Schedule" and let cron reindex data. Otherwise, every time an object is saved reindex will happen and lead to high CPU usage and MySQL errors. As a best practice, Magento recommend that you use scheduled indexing.

Use Update on Schedule instead of Update on Save to run the re-index process with CRON.

Update on Schedule is better than Update on Save. Magento also recommends using the Update on Schedule mode in production because it stores information about data updates and performs indexation by portions in the background through a specific cron job.

Whether the Update on Save mode immediately indexes whenever your catalog or other data changes. It can lead to significant delays and data unavailability during high loads. This mode assumes a low intensity of update and browsing operations in your store.

Check the below official Magento guide for more information regarding indexing. https://docs.magento.com/user-guide/system/index-management.html
