Hi All, I am new in learning ruby on rails. And now I’m trying to do set up for ruby on rails in IIS I follow instructions from one of site and then when I try to run the page [http://localhost/index.rhtml](http://localhost/index.rhtml), it comes an error like this : CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: C:\first\app\views\first\index.rhtml:9: undefined method `form\_tag’ for main:Object (NoMethodError) Does anyone here know what’s wrong? maybe i’ve missed some settings but i have no idea what is wrong Thanks a lot in advance for your help best regards, Jaan ---

Jaan. ``` I would recommend first running the application using Webrick, or ``` Mongrel to be sure it is working properly, right now you are trying to access directly a rhtml template, and you have error in it. ``` And after that start try serving it using some of the recipes in: http://www.napcs.com/howto/rails/deploy/ ``` – Aníbal On Feb 14, 7:06 pm, Jaan J.

Having been doiing rails development in wndows and linux for a while now. Always start your testing using mongel, using ruby script/server in your project direcotry. (Or your ide can run it). In production for a small set of users, run a single mongrel as a windows service, you can always redirect using a web page in iis if your really must use iis. For production, windows is not the way to go for anything serious. Using nginx and a mongrel cluster. ---

Hi Anibal and glennswest, Thanks a lot for your help. I tried to use Mongrel and integrate it with IIS and now it’s working Thanks guys Just one more thing, now it’s running for single Mongrel what i’m trying to do now for next step is I want to run another Rails application but I dont want to create another Mongrel service I read from somewhere that I can use Mongrel cluster But after I created mongrel cluster with mongrel\_cluster.yml, when I tried to start my mongrel\_cluster service, it returns error something like this : C:\rails\myapp1\>mongrel\_rails cluster::start starting port 3010 c:/ruby/lib/ruby/gems/1.8/gems/mongrel\_cluster-1.0.5/lib/mongrel\_cluster/init.rb:98: in ``’: Exec format error - mongrel\_rails start -d -e production -a 127.0.0.1 -c C:\rails\myapp1 --prefix /myapp1 -p 3010 -P tmp/pids/mongrel.3010.pid -l log/mongrel.3010.log (Errno::ENOEXEC) … … from c:/ruby/bin/mongrel\_rails:16:in ‘load’ from c:/ruby/bin/mongrel\_rails:16 Can you guys give me clue how to solve this matter?

That is design limitation of Rails and not Mongrel. > I read from somewhere that I can use Mongrel cluster > But after I created mongrel cluster with mongrel\_cluster.yml, when I > tried to start my mongrel\_cluster service, it returns error something > like this : Mongrel cluster leverage in functionality only available in posix compliant OS (forking also known as daemonize). That is not possible to implement in Windows without replacing things and adding big conditional blocks to call Win32 API. In any case, having one service for each application is a good practice. You can restart each application individually from each other. In case you want to implement a “cluster” of the same application, that’s another story that currently is not doable with mongrel\_service. Right now the only workaround is creating a service for each application port: my-app-3000 my-app-3001 my-app-3002 etc. Then you can trick all these services to depend on the previous one, so doing a “net start my-app-3004” will cascade the net start command down to my-app-3000. That’s a nice trick but can be tricky get it set (maybe it deserves a separate post) 😃 ## Regards, ## Luis L.

Hi Luis, Ah okey so it’s really not possible to use same ruby process for multiple rails applications… Thanks for your help. It’s working now for me after I made 2 mongrel services for 2 different rails applications and then added 2 lines for RewriteProxy(for each mongrel services) in my ISAPI Rewrite 3 Thanks Luis Best regards, Jaan ---
