sample nginx.conf

Description of problem:
Due to configure arguments, a user cannot completely run nginx as a non-root user.

Version-Release number of selected component (if applicable):
nginx 1.6.2

How reproducible:
Always

Steps to Reproduce:
1. Enable Red Hat Software Collections repository
2. Install with "yum install -y nginx16"
3. Use the attached nginx.conf file and run "/opt/rh/nginx16/root/sbin/nginx -c /tmp/nginx.conf" as a non-privileged user.

Actual results:
$ /opt/rh/nginx16/root/sbin/nginx -c /tmp/nginx.conf
nginx: [alert] could not open error log file: open() "/var/log/nginx16/error.log" failed (13: Permission denied)
2016/08/30 12:10:37 [emerg] 13899#0: mkdir() "/opt/rh/nginx16/root/var/lib/nginx/tmp/client_body" failed (13: Permission denied)

Expected results:
nginx should startup, spawn worker processes and begin handling requests.

Additional info:
The error_log option doesn't seem to be overriding the --error-log-path option as it should according to the nginx documentation [1]. Same goes for the --http-proxy-temp-path option.

Here is the nginx -V output:
