Hi, I am wanting to reverse proxy to a number of servers running on different ports on one machine. These servers will come and go. Is it possible to dynamically change the nginx mappings without having to bounce the server?

Dynamic upstream management has been something on my wishlist for a while. It would make nginx a smarter load balancer… I believe Piotr or someone else might have something started for this though (in combination with a module) not sure.d ---

hi, > It sounds like dynamic upstream management is exactly > what I’m after. It would be great if anyone has any news > on any work that is happening in that area. sounds good to me as well. what would be on my wishlist is a module for dynamically assigning upstream weights based on criteria like for example load-1/-5/-15 of the backend server.. that would be great 🙂 🙂 greetings ---

Hi, It sounds like dynamic upstream management is exactly what I’m after. It would be great if anyone has any news on any work that is happening in that area. Thanks.

Hi, I thought that people on this mailing list knew about this piece of software, but since it hasn’t been mentioned, I’ll point you to Nginxmgr: [http://just-another.net/2009/10/21/nginxmgr-nginx-upstream-pool-manager/](http://just-another.net/2009/10/21/nginxmgr-nginx-upstream-pool-manager/) I haven’t tried it, though.
