$ps -ef | grep apache | grep -v grep  

Output:

The same thing working fine with Centos, Ubuntu and other OSes but on Red Hat problem is still there.

According to your question, the command you have typed is:

#chmod -R 777 /var/www/html/backend/web/assets

Since you want to change the permission of that folder, you need to have a elevated user privileges. Hence append sudo before your query to provide the elevated user privileges to the command and to change the directory permissions
