===About Mod_PageSpeed===

===About Mod_PageSpeed===

mod_pagespeed is an Apache, and ngix, module that automatically optimizes web content using a variety of method including compression.  Alot of the optimization that mod_pagespeed does are based upon recomendations seen through Google's PageSpeed Insights testing utility (https://pagespeed.web.dev/).  My experience with my production web content, especially CMS content, is that this module can result in a significant performance increase to your web content.

The mod_pagespeed Apache module is now installed on your SME Server, but the module is not yet integrated into the Apache configuration.  To do this, we will create a custom template to include the property configuration information in httpd.conf to load the module.  

The mod_PageSpeed Apache module is now installed on your SME Server, but the module is not yet integrated into the Apache configuration.  To do this, we will create a custom template to include the property configuration information in httpd.conf to load the module.  

First, let's create the custom-template fragment:

First, let's create the custom-template fragment:

  [root@sme ~]# mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf

  [root@sme ~]# mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf

  [root@sme ~]# touch /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/20LoadModule99Pagespeed

  [root@sme ~]# touch /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/20LoadModule99Pagespeed

Next, let's add the mod_pagespeed configuration information to the fragment:

Next, let's add the mod_PageSpeed configuration information to the fragment:

  [root@sme ~]# vi /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/20LoadModule99Pagespeed

  [root@sme ~]# vi /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/20LoadModule99Pagespeed

  [root@sme ~]# expand-template /etc/httpd/conf/httpd.conf

  [root@sme ~]# expand-template /etc/httpd/conf/httpd.conf

  [root@sme ~]# systemctl restart httpd-e-smith.service

  [root@sme ~]# systemctl restart httpd-e-smith.service

Now, let's verify the mod_pagespeed module is loaded:

Now, let's verify the mod_PageSpeed module is loaded:

  [root@sme ~]# apachectl -M | grep pagespeed

  [root@sme ~]# apachectl -M | grep pagespeed

   pagespeed_module (shared)

That's it, you are good to go and mod_pagespeed should now be optimizing your web content.

===Testing That mod_PageSpeed is Optimizing Content===

===Testing That mod_PageSpeed is Optimizing Content===

To test your web content to see if mod_PageSpeed is optimizing content, you can use the curl command to view headers and look for the X-Mod-Pagespeed header or use this website utility:  https://websniffer.cc/  Simply input your website URL and websniffer will report the page headers for the URL.  Look for the X-Mod-Pagespeed similar to this:

If you are seeing the X-Mod-Pagespeed HTTP response header, then your web content is being optimizing.
