Adding Pagespeed module in Apache is very easy with package manager:
sudo yum install at # if you do not already have 'at' installed sudo rpm -U mod-pagespeed-*.rpm
... but if we want to add Pagespeed module in Nginx, first thing we think of is compiling its source along with the Pagespeed module. What if Nginx is installed in our server from yum or rpm? The process we need is to repackage RPM and that is what this tutorial will show.
