The team at bitly has written an http reverse proxy that provides authentication using Google's OAuth2 API. They write about it in a blog post.
The proxy is written in Go but builds to a single, statically-linked executable, ie. there are no complex run-time dependencies, which is great.
I've built an RPM for EL7 which also includes a sample systemd unit file, and sample configuration file. Both source and binary RPMs are available in my yum repo.
Additionally, I've create a puppet module that installs the RPM, creates a systemd service, and sets up an nginx front end to the proxy service. The module is available from the Puppetforge, and also on github.
I'd be interested in any feedback/comments/bug reports/pull requests.
I recently had need to install uwsgi on EL7 (CentOS 7, actually, but RHEL 7 will be the same).
I ended up rebuilding the uwsgi SRPM from Fedora 21 which was relatively straight-forward but it required a few tweaks to the .spec file. I also had to build a chain of dependencies: mongodb, perl-Cora, libecb, perl-EV, libev, zeromq, perl-BDB, perl-AnyEvent-BDB, perl-AnyEvent-AIO.
All packages (including SRPMs) are in my repo: http://repo.yo61.net/el/7/
