Use PageSpeed with Apache

Check if PageSpeed is enabled

There are different ways to check if mod_pagespeed for Apache is already configured and running.

• Check if the module and configuration files are active, by inspecting the /opt/bitnami/apache/conf/httpd.conf and looking for the following lines:

    Include conf/pagespeed.conf
    Include conf/pagespeed_libraries.conf
  

  The module will be located at /opt/bitnami/apache/modules/mod_pagespeed_ap24.so.

• Check the source code of rendered application page. Images, CSS and JavaScript should appear in compressed form. For example, an image might be named sample.png.pagespeed.ic.ZWx38TQ7J5.png.

Check Pagespeed statistics

For security reasons, the PageSpeed application is accessible only when using 127.0.0.1 as the hostname. To access it from other IP addresses, follow these steps:

• Enable remote access by editing the /opt/bitnami/apache/conf/pagespeed.conf file, disabling URL rewriting and replacing the SERVER-IP placeholder with your public IP address. Obtain your public IP address from https://myip.bitnami.com if required. Ensure that the final result looks like this:

    <Location /pagespeed_admin>
        <IfModule mod_rewrite.c>
          RewriteEngine Off
        </IfModule>
        Order allow,deny
        Allow from localhost
        Allow from 127.0.0.1
        Allow from SERVER-IP
        SetHandler pagespeed_admin
    </Location>
    <Location /pagespeed_global_admin>
      <IfModule mod_rewrite.c>
        RewriteEngine Off
      </IfModule>
        Order allow,deny
        Allow from localhost
        Allow from 127.0.0.1
        Allow from SERVER-IP
        SetHandler pagespeed_global_admin
    </Location>
  

• Restart Apache to load the changes:

    $ sudo /opt/bitnami/ctlscript.sh restart apache
  

You should now be able to check PageSpeed statistics by browsing to http://SERVER-IP/pagespeed_admin. Here is an example of what you should see:

TIP: Alternatively, check PageSpeed statistics using an SSH tunnel.

Disable PageSpeed

To disable PageSpeed, follow these steps:

• Comment out the following lines in the /opt/bitnami/apache/conf/httpd.conf file:

    #Include conf/pagespeed.conf
    #Include conf/pagespeed_libraries.conf
  

• Restart Apache:

    $ sudo /opt/bitnami/ctlscript.sh restart apache
  

Flush the PageSpeed cache

To flush the PageSpeed cache, follow these steps:

• Execute this command:

    $ sudo touch /opt/bitnami/apache/var/cache/mod_pagespeed/cache.flush
  

• Restart Apache:

    $ sudo /opt/bitnami/ctlscript.sh restart apache
