How to: Install mod_pagespeed in cpanel

How to: Install mod_pagespeed in cpanel

Login to the server via SSH

Go to below folder

cd /usr/local/src

create directory

mkdir mod_pagespeed

Download pagespeed rpm


Extract the rpm

rpm2cpio mod-pagespeed-beta_current_i386.rpm | cpio -idmv

Copy the modules to apache modules folder

cp /usr/local/src/mod-pagespeed/usr/lib/httpd/modules/ /usr/local/apache/modules/

cp /usr/local/src/mod-pagespeed/etc/httpd/conf.d/pagespeed.conf /usr/local/apache/conf/

Provide execute permission

chmod 755 /usr/local/apache/modules/

Create below folders

mkdir /var/mod_pagespeed/{cache,files} -p

Provide correct ownership

chown nobody:nobody /var/mod_pagespeed/*

mod_pagespeed has a dependency that you’ll want to enable: mod_deflate (the httpd source directory (2.2.16) may vary depending on your install):

/usr/local/apache/bin/apxs -c -i /home/cpeasyapache/src/httpd-2.2.16/modules/filters/mod_deflate.c

We have to edit mod_pagespeed configuration file located at /usr/local/apache/conf/pagespeed.conf to reflect the correct paths, the LoadModule directives should fetch the modules in “modules/”

LoadModule pagespeed_module modules/
LoadModule deflate_module modules/
ModPagespeedFileCachePath "/var/mod_pagespeed/cache/"
ModPagespeedGeneratedFilePrefix "/var/mod_pagespeed/files/"

After that, we’ll need to include the mod_pagespeed configuration in Apache’s configuration file (/usr/local/apache/conf/httpd.conf):

Include conf/pagespeed.conf

In order to keep the changes permanant run the command below.

/usr/local/cpanel/bin/apache_conf_distiller –update

Now restart apache service.
