Is there any way to configure nginx (or other quick reverse proxy) dynamically?

Question

Suppose we have several identical nodes which are the application servers of some n-tier service. And suppose we use Apache ZooKeeper to keep all the config\'s of our distribute

Answer 1

Not sure that it is possible to dynamicaly change nginx configuration without restarting a server.

If I had a same requirement I'd probably dug into nodejs and zookeeper integration.

There are several interesting opensource projects:

node-zookeeper integrates nodejs with zookeeper;

node-http-proxy proxy http server that can be used for load balancing.

Of course they lack maturity but they might be interesting for you.

Answer 2

This may be late but if you have the money. Nginx plus is exactly for you. It uses a simple url call to get new configurations on the fly.
