Mod-pagespeed Notes

In this guide, I’ll be installing mod_pagespeed on a 64-bit CentOS 5.5 system. The host is example.com.

\n

Installation

\n

Grab the most appropriate RPM and install it.

\n
rpm -ivh https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_x86_64.rpm\n
\n

This is the RPM manifest on a 64-bit system:

\n
/etc/cron.daily/mod-pagespeed\n/etc/httpd/conf.d/pagespeed.conf\n/usr/lib64/httpd/modules/mod_pagespeed.so\n/var/www/mod_pagespeed/cache\n/var/www/mod_pagespeed/files\n
\n

Testing

\n

To check for a proper install, you can do two things:

\n
    \n
  • Check if the /var/www/mod_pagespeed directories are populated, or
    • \n
  • Use curl or wget to check for the appropriate header.
    • \n
\n

Checking headers

\n

Let’s use wget:

\n
wget -O - --server-response http://example.com/home/index.php > /dev/null\n
\n

Here’s the response:

\n
--2011-01-05 09:01:36--  http://example.com/home/index.php\nResolving example.com... 128.255.22.132\nConnecting to example.com|128.255.22.132|:80... connected.\nHTTP request sent, awaiting response...\n  HTTP/1.1 200 OK\n  Date: Wed, 05 Jan 2011 15:01:36 GMT\n  Server: Apache/2.2.3 (CentOS)\n  X-Powered-By: PHP/5.2.10\n  X-Mod-Pagespeed: 0.9.11.5-293\n  Vary: Accept-Encoding\n  Content-Length: 4657\n  Connection: close\n  Content-Type: text/html; charset=UTF-8\nLength: 4657 (4.5K) [text/html]\nSaving to: `STDOUT'\n\n100%[========================================>] 4,657       --.-K/s   in 0s\n\n2011-01-05 09:01:36 (211 MB/s) - `-' saved [4657/4657]\n
\n

The X-Mod-Pagespeed header should tell you that pagespeed is in action.

\n

Tweaking Pagespeed

\n

Pagespeed has 18 ‘filters’ with which you can tweak for performance. For example, I can remove all HTML comments with this filter in /etc/httpd/conf.d/pagespeed.conf

\n
ModPagespeedEnableFilters remove_comments\n
\n

To see a “before-and-after”, append ?ModPagespeed=off to any page served up. This page does a good job of explaining other filters. You can also check the documentation.

\n

Viewing statistics

\n

The /etc/httpd/conf.d/pagespeed.conf config defines /mod_pagespeed_statistics as a page where you can take a look at pagspeed’s statistics.
