Had some trouble installing wkhtmltopdf on CentOS 6, so here are the commands to do it:
Install fonts, then icu, then the CentOS 6 RPM for wkhtmltopdf, then x11-server and urw-fonts!
yum install -y xorg-x11-fonts-75dpi yum install -y xorg-x11-fonts-Type1 yum install icu wget https://bitbucket.org/wkhtmltopdf/wkhtmltopdf/downloads/wkhtmltox-0.13.0-alpha-7b36694_linux-centos6-amd64.rpm rpm -Uvh wkhtmltox-0.13.0-alpha-7b36694_linux-centos6-amd64.rpm cd ~website yum install xorg-x11-server-Xvfb.x86_64 yum install urw-fonts export DISPLAY=:0 export QT_XKB_CONFIG_ROOT=/usr/share/X11/xkb xvfb-run wkhtmltopdf http://www.google.com.ph google.pdf
