Round-robin Django setup with nginx. An nginx trick I didn’t know: a low proxy_connect_timeout value (e.g. 2 seconds) combined with the proxy_next_upstream setting means that if one of your backends breaks a user won’t even see an error, they’ll just have a short delay before getting a response from a working server. # 21st December 2009, 3:43 pm

Simple CouchDB multi-master clustering via Nginx. An impressive combination. CouchDB can be easily set up in a multi-master configuration, where writes to one master are replicated to the other and vice versa. This makes setting up a reliable CouchDB cluster is as simple as putting two such servers behind a single nginx proxy. # 19th November 2009, 4:37 pm

How We Made GitHub Fast. Detailed overview of the new GitHub architecture. It’s a lot more complicated than I would have expected—lots of moving parts are involved in ensuring they can scale horizontally when they need to. Interesting components include nginx, Unicorn, Rails, DRBD, HAProxy, Redis, Erlang, memcached, SSH, git and a bunch of interesting new open source projects produced by the GitHub team such as BERT/Ernie and ProxyMachine. # 21st October 2009, 9:14 pm

nginx_http_push_module. More clever design with webhooks—here’s an nginx module that provides a comet endpoint URL which will hang until a back end process POSTs to another URL on the same server. This makes it much easier to build asynchronous comet apps using regular synchronous web frameworks such as Django, PHP and Rails. # 17th October 2009, 4:48 pm

Ravelry. Tim Bray interviews Casey Forbes, the single engineer behind Ravelry, the knitting community that serves 10 million Rails requests a day using just seven physical servers, MySQL, Sphinx, memcached, nginx, haproxy, passenger and Tokyo Cabinet. # 3rd September 2009, 6:50 pm

Phusion Passenger for nginx. Passenger (aka mod_rails / mod_rack) enables easy deployment of Rails and Ruby apps under Apache... and the latest version adds support for nginx as well. It works as an HTTP proxy and process manager, spawning worker processes and forwarding HTTP requests to them via a request queue. It can also handle Python WSGI applications—anyone tried it out for that yet? # 20th April 2009, 4:53 am

Paul Buchheit: Make your site faster and cheaper to operate in one easy step. Paul promotes gzip encoding using nginx as a proxy, and mentions that FriendFeed use a “custom, epoll-based python server” as their application server. Does that mean that they’re serving their real-time comet feeds directly from Python? # 17th April 2009, 5:19 pm

How to use Django with Apache and mod_wsgi. My favourite deployment option is now included in the official Django docs, thanks to Alex Gaynor. I tend to run a stripped down Apache with mod_wsgi behind an nginx proxy, and have nginx serve static files directly. This avoids the need for a completely separate media server (although a separate media domain is still a good idea for better client-side performance). # 1st April 2009, 12:24 am

Future roadmap for mod_wsgi. mod_wsgi 3.0 isn’t too far off, and will include Python 3.0 support, WSGI application preloading and internal web server redirection (similar to nginx X-Accel-Redirect). Version 4.0 plans a major architectural change that will allow multiple versions of Python to be run from the same Apache. # 19th March 2009, 5:27 pm

The Django and Ubuntu Intrepid Almanac. Will Larson’s impressively comprehensive guide to configuring and securing an Ubuntu VPS from scratch to run Django, using PostgreSQL and Apache/mod_wsgi behind nginx. # 14th February 2009, 3:42 pm
