Install mod_pagespeed on WHM

With EA3:

/usr/local/cpanel/3rdparty/bin/git clone /tmp/pagespeed/
cd /tmp/pagespeed/Easy
tar -zcvf pagespeed
mkdir -p /var/cpanel/easy/apache/custom_opt_mods/Cpanel/Easy
mv -t /var/cpanel/easy/apache/custom_opt_mods/Cpanel/Easy/
cd && rm -rf /tmp/pagespeed

With EA4: Create file /etc/rpm/macros.apache2 and add the following lines of code exactly as below

%_httpd_mmn 20120211x8664
%_httpd_apxs /usr/bin/apxs
%_httpd_dir /etc/apache2
%_httpd_bindir %{_httpd_dir}/bin
%_httpd_modconfdir %{_httpd_dir}/conf.modules.d
%_httpd_confdir %{_httpd_dir}/conf.d
%_httpd_contentdir /usr/share/apache2
%_httpd_moddir /usr/lib64/apache2/modules

Next run the following commands in order, make sure you run each command on it’s own

rm -rf /root/rpmbuild/RPMS/x86_64/
rpmbuild --rebuild ea-apache24-mod_pagespeed-latest-stable.src.rpm
rpm -Uvh /root/rpmbuild/RPMS/x86_64/ea-apache24-mod_pagespeed*.rpm
/etc/init.d/httpd restart
