Use PageSpeed

Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and Mac OS X) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). Learn more.

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 installdir/apache2/conf/httpd.conf and looking for the following lines:

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

    The module will be located at installdir/apache2/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 installdir/apache2/conf/pagespeed.conf file and adding your IP address to the list of allowed IP address:

    <Location /mod_pagespeed_statistics>
        Order allow,deny
        Allow from localhost
        Allow from 127.0.0.1
        Allow from localhost
        SetHandler pagespeed_console
    </Location>
    

Do the same for the /pagespeed_console and /mod_pagespeed_message sections. On some versions, this is also called /pagespeed_admin.

  • Restart Apache to load the changes:

    $ cd installdir
    $ ./ctlscript.sh restart apache
    

Here is an example of what you should see:

PageSpeed console

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

Disable PageSpeed

To disable PageSpeed, follow these steps:

  • Comment out the following lines in the installdir/apache2/conf/httpd.conf file:

    Include conf/pagespeed.conf
    Include conf/pagespeed_libraries.conf
    
  • Restart Apache:

    $ sudo installdir/ctlscript.sh restart apache
    

Flush the PageSpeed cache

To flush the PageSpeed cache, follow these steps:

  • Execute this command:

    $ sudo touch installdir/apache2/var/cache/mod_pagespeed/cache.flush
    
  • Restart Apache:

    $ sudo installdir/ctlscript.sh restart apache
