Pow (http://pow.cx/) functionality for Linux & nginx.

Pow - the hairy way.md

Create required dirs:

mkdir ~/.pow # where play will register the http.port
mkdir ~/.nginx-sites # where pow will create proxy configs

Tell nginx to load sites config from your ~/.nginx-sites by adding this to /etc/nginx.conf:

http {
    ...
    
    include /home/<user>/.nginx-sites/*;
}

Install dnsmasq and add this to /etc/dnsmask.conf:

address=/dev/127.0.0.1

Setup is complete. To run the daemon script:

sudo linux-nginx-pow

The script will run forever, watching for ~/.pow/* files and creating nginx proxy configs accordingly in ~/.nginx-sites. It has to be run as root, so it can refresh nginx config with pkill -HUP nginx.
