Answer 2

My problem has been solved. Let me show what the solution :

I tried different function of bin/magento such as "bin/magento setup" or "bin/magento cache" but it will show "There are no commands defined in the XXXXX namespace" I think it is the all function of bin/magento problem not only indexer. So, I run the following command :

$ php bin/magento list

They can not list the function and notice me some error. I think it is the access right problem so I change the owner to all folder again.

$ chown -R XXXX:www-data

Finally, all function of bin/magento are working.

you have to check your permissions try: sudo chown -R XXX:www-data /var/www cd /var/www chmod go-rwx /var/www chgrp -R www-data /var/www chmod -R go-rwx /var/www chmod -R g+rx /var/www chmod -R g+rwx /var/www sudo chown -R XXX:www-data /var/www/<magento folder>/ cd <magento folder>/public_html/ find var generated vendor pub/static pub/media app/etc -type f -exec chmod g+w {} + && sudo find var generated vendor pub/static pub/media app/etc -type d -exec chmod g+ws {} + && sudo chown -R :www-data . && sudo chmod u+x bin/magento

Remember to Change XXX with your pc name, also it's: php bin/magento indexer:reindex : instead of .

Answer 4

please replace . to : in your command.

Follow this

Hope it is working fine.
