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:

[root@sme ~]# expand-template /etc/httpd/conf/httpd.conf
[root@sme ~]# systemctl restart httpd-e-smith.service

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

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===
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.
