How to dynamically reload nginx config

view full story
linux-howto

http://serverfault.com – I'm currently trying to setup Nginx for a domain with production, testing and development stages. Each comes with it's own partial Nginx config file with rewrites. The production and testing stages are set up as branches from a Git repository and automatic reloading of these configurations in Git's post-receive hook. This all works just fine. The development stage I'd like to transmit using SFTP using Netbeans' "SFTP-on-save" as I don't need version control at this granularity and it's a bit more direct. However, here I have no such thing as git's post-receive hook to trigger Nginx to reload (HowTos)

Stories similar to How to dynamically reload nginx config

I added a server stanza to my virtual.conf, and now nginx seems to have a problem reloading the config.

At this point I don't know what exactly is going wrong or how to debug better.

I'm using Passenger + Nginx to run a Rails app. If i use "rails_env development;" the application works fine.

I am on Ubuntu 12.04, I have the latest stable version of nginx added to my ppa

sudo add-apt-repository ppa:nginx/stable -y

It has been running perfectly for nearly a year.

I am running nginx on Windows Server 2008 R2 (x64) as a windows service. I am using Windows Service Wrapper for that. (Actually, I have followed this tutorial: http://mercurial.selenic.com/wiki/HgServeNginxWindows.)

The service is running ok. However, the server does not process the signals (e.g. stop / reload).

This means if I stop the service, nginx is not stopped.

I wanted to ask about Nginx Retry of Requests. I have a Nginx running at the backend which then sends the requests to HaProxy which then passes it on the web server and the request is processed. I am reloading my Haproxy config dynamically to provide elasticity. The problem is that the requests are dropped when I reload Haproxy.

Nginx is a lightweight web server (HTTP, SMTP, IMAP, POP3 ..). It has very low memory footprints with higher degree of concurrency.

I am currently testing out nginx and have set up some virtual hosts by putting configurations for each virtual host in its own file in a folder called sites-enabled.

I then ask nginx to load all those config files using:

include C:/nginx/sites-enabled/*.conf;

This is my current config:

http { server_names_hash_bucket_size 64;

include mime.types; include C:/ngin

When reloading config (specifically for proxy_pass) - occasionally this will be seen: nginx: [emerg] host not found in upstream

However - the upstream server's name WILL resolve in the os (linux) - only nginx seems to have this problem.

This seems to be a recent regression - as it didn't seem to happen previous to 1.0.10 versions.

Has anyone noticed this recently?

I am using Nginx + PHP-FPM to run a Wordpress based site. I have a URL that should return dynamically generated JSON data for use with the DataTables jQuery plugin. The data is returned properly, but with a return code of 404. I think this is a Nginx config issue, but I haven't been able to figure out why.
