connect() to failed (13 permission denied)

역시... 생각한대로 SELinux  때문에 생긴 문제 였던것 같다.. 하아.. 이게 맞앗어 그래..

I had a similar issue getting Fedora 20, Nginx, Node.js, and Ghost (blog) to work. It turns out my issue was due to SELinux.

This should solve the problem:

setsebool -P httpd_can_network_connect 1

Details

I checked for errors in the SELinux logs:

sudo cat /var/log/audit/audit.log | grep nginx | grep denied

And found that running the following commands fixed my issue:

sudo cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M mynginx
sudo semodule -i mynginx.pp
