Rails 3 - Windows + Mongrel (Error with dispatcher)

问题

I am trying to deploy a rails 3 app to a windows machine (yes it has to be windows, I cannot use linux)

I decided to try and use Mongrel + Apache (willing to try other setups if anyone knows one that works).

I have mongrel installed and I can run rails server mongrel and run my app fine. However when I try to start mongrel as a windows service using

mongrel_rails service::install -N mongrel1 -e production -p 3001 -c mydirectory`

I run into trouble. The server starts fine but when I try to get onto the web page I get the following error generated in my mongrel.log file.

Error calling Dispatcher.dispatch #<NameError: uninitialized constant ActionController::CgiRequest>

I have tried to read up on this but all the setup guides seem to be very dated.

回答1:

I am running a Rails 3 app on Windows (Win7) using Apache + Mongrel. Here is perhaps another approach. In httpd.conf I set DocumentRoot as the path to my rails app. The Directory tag is then set to whatever Document Root is. Then add a VirtualHost tag as follows:

<VirtualHost localhost:80>
  Servername YourAppServer
  DocumentRoot "same path as before"
  ProxyPass / http://localhost:3000/
  ProxyPassReverse / http://localhost:3000/
  ProxyPreserveHost On
</VirtualHost>"

ServerName value I think is arbitrary.

You also need to add: LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_http_module modules/mod_proxy_http.so

I suppose that if you are using port 3001 instead of 3000, you make the appropriate substitutions.

Then start everything (from your app folder) with 'rails server -e production -p 3001' (Apache should already be running)
