Speed Up the Web with Google Page Speed = Apache2
If you’re on a 64-bit version (likely)…
If you’re on a 32-bit version (less likely)…
sudo dpkg -i mod-pagespeed-*.deb apt-get -f install
Remove the downloaded package
service apache2 restart
The installation package handles a lot of configuration out-of-the-box. In fact, there are conservative defaults that are automatically enabled on Apache. Depending on the Apache version you’re running, you’ll get a different version of the module installed and enabled. If you’re running Apache 2.2,
mod_pagespeed.so will be installed; Apache 2.4 users will use
Note: mod_pagespeed only works with Apache 2.2 and greater. There is also a bug with Apache 2.4.1 that prevents it from working with that version. Apache 2.4.2 or greater should be used.
Additionally, configuration files have been added to your Apache installation. The primary configuration file is
pagespeed.conf. This file is located at:
Turn mod_pagespeed On/Off
First off, you can turn the module on or off with the ModPagespeed setting.
You can specify different “levels” of settings to simplify any configuration. The default is
“CoreFilters.” It contains a set of filters the Google team believes is safe for use. The filters are the individual actions that are applied to a file. In general, you won’t need to change this value. It’s easier to use this default and then enable or disable filters using the
The default setting:
To disable CoreFilters use this setting:
Note: You’ll have to explicitly enable any filters you want to turn on using the “
Using the default “CoreFilters” rewrite level includes a number of filters by default. As of the time of this writing, it includes:?
New filters will be added in the future. By using CoreFilters, you’ll automatically have these filters enabled if they become part of the default set whenever you update mod_pagespeed. Using PassThrough will require you to explicitly enable the new filters.
If you’d like to enable additional filters, you can pass them as a comma-separated list to
ModPagespeedEnableFilters. You can have multiple ModPagespeedEnableFilters directives throughout your configuration files. So, if you want to enable a filter per site, you could enable it in the virtual host configuration file or in the .htaccess file instead of in the main pagespeed.conf file.
Here’s an example that enables the Pedantic filter (which adds the type attribute to script and style tags) and the Remove Comment filter (which removes all HTML comments):
You can also disable filters on a per-case basis if you’d like. Specify a list of filters you’d like to disable similar to
The following example disables the “Convert JPEG to Progressive” filter even though it’s part of the CoreFilters set:
Specify Which URLs are Rewritten
This would disable rewriting of any files that match the wildcard pattern specified (jquery UI in this case).
You can also turn off the rewriting of all files by default and only enable files you want to rewrite manually. You can do this with the following settings:
ModPagespeedDisallow "*" ModPagespeedAllow "http://*digitalocean.com/*/styles/*.css" ModPagespeedAllow "http://*digitalocean.com/*.html" ModPagespeedDisallow "*/notrewritten.html"
The order of execution means that all files at digitalocean.com ending in .html would be rewritten. That last Disallow directive means any URLs matching that pattern would not be rewritten because it overrides the previous setting.
Don’t forget if you’re using the pagespeed.conf or VirtualHost files to alter the settings, you’ll have to restart Apache for the settings to take effect. You can do this with the following commands:
service apache2 restart or /etc/init.d/apache2 restart
