【问题描述】：
我在 openshift rhc 中有一个站点，所以我想在 Openshift Rhc 服务器中使用 nginx 软件创建一个保留代理，从该服务器可以使用 nginx 访问许多其他服务器，所以我通过这种配置配置了我的 nginx 服务器：
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
error_log {{OPENSHIFT_HOMEDIR}}/app-root/logs/nginx_error.log debug;

# set "proxy_buffering off" *only* for Rainbows! when doing

# clients, even with Rails 3.1 streaming because otherwise a slow
# client can become a bottleneck of Unicorn.
#
# The Rack application may also set "X-Accel-Buffering (yes|no)"
# in the response headers do disable/enable buffering on a
# per-response basis.

我使用了上游索引：
upstream index {
server free-papers.elasa.ir weight=1;
server diy4tornado-tornado4ss.rhcloud.com weight=2;
}
但是当我使用此配置（使用 cloudflare 或 rhc 服务器）时，我从 cloudflare 收到此错误：
cloudflare 不允许直接 IP 访问
那么对于此类服务器，nginx 或 Apache 服务器软件的正确配置是什么。
非常感谢您的关注。
