TileStache and NGinx - ruby-on-rails-3

Question

I am building a mapping application and am using TileStache for tile generation and caching. I am already using NGinx+Passenger for my rails app and am trying to figure out how to serve both my rails app and TileStache from the same web server (NGinx). From the NGinx documentation it looks like NGinx need to be re-compiled to add the WSGI module. Since I am already using Phusion Passenger module I am not sure how to go about doing this. Am I on the right track? Any suggestions would be appreciated.

Answer 1

Since for this specific project the data is static I have decided to use TileStache to seed/warm the cache and server the tiles as static assets.

Answer 2

We use nginx to serve the tiles out. Works great.
We configure nginx to proxy_pass to the wsgi server. In the sites-enabled file:
location / {
proxy_pass http://127.0.0.1:XXXXSOMEPORTXXXX;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_connect_timeout 900s;
proxy_read_timeout 900s;
}
I gave it a long timeout so the client can wait awhile, you might want less.
I then created a python virtual environment and installed gunicorn to run the tilestache server. It can be run with a command like this:
XXXXPATHTOVIRTUALENVXXXX/bin/gunicorn --max-requests 1 --timeout 900 --graceful-timeout 890 -b 127.0.0.1:XXXXSOMEPORTXXXX -w 20 "TileStache:WSGITileServer('XXXXPATHTOTILESCONFIGXXXX/tiles.conf')"
We keep gunicorn running by using that line in supervisord so supervisor is responsible for firing up the gunicorn server when it terminates or the system restarts.
Tilestache is pretty awesome!
