wicked_pdf does not run on Ubuntu server : wkhtmltopdf: cannot connect to X server

Question

I\'m trying to use wicked_pdf on my prod server but it keeps failling :

RuntimeError (Failed to execute:
\"/usr/bin/wkhtmltopdf\" -q        \"file:////tmp/wicked         


        

Answer 1

1. Verify you have xvfb installed, or install it using apt-get install xvfb.

2. Create a file called wkhtmltopdf.sh and add the following:

   xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf $*
   

   Change the dimensions (640x480x16) to match whatever virtual screen parameters you want it to emulate.

3. Move the shell script to /usr/bin, and set permissions:

   sudo chmod a+x /usr/bin/wkhtmltopdf.sh
   

4. Optionally, you can add a symbolic link in your project directory:

   ln -s /usr/bin/wkhtmltopdf.sh wkhtmltopdf
   

See this and this for reference.
