Scheduled index not working / Products show after running manual index

Question

I have a Magento CE 2.1 site. Products are not showing up until after a manual index is run.

Index is set to run on schedule. Cron is running

*/1 * * * * php -f /path/to/Magento2.1CE/bin/magento cron:run  &> /dev/null
*/1 * * * * php -f /path/to/Magento2.1CE/update/cron.php &> /dev/null
*/1 * * * * php -f /path/to//Magento2.1CE/bin/magento setup:cron:run &> /dev/null

Tested it this way

php -f /path/to/Magento2.1CE/bin/magento cron:run

Ran jobs by schedule.

Answer 1

Khoa started me on this answer:

This is a shared server from Nexcess and I am under the impression there is multiple versions of PHP running.

The indexing started to work when I switched to

/opt/nexcess/php56u/root/usr/bin/php

Which I easily found like this

$ which php
/opt/nexcess/php56u/root/usr/bin/php

Indexing is working fine now.
