Hi peter, thanks for sharing the recipe. I followed most of the steps to deploy web2py with nginx and uwsgi in a CentOS ver 5.8 VPS host, but nginx is serving only the static default page. <host ip>/welcome or other url will fail with:
502 Bad Gateway ------------------------------ nginx/1.2.2 nginx was installed via yum, build uwsgi from source and stored it in etc/wsgi-python, and also installed Python 2.7.3 from source. I had to change some locations in the config files to adapt to the actual server installations Is there any shell or web server test I can perform to detect configuration issues?
