mod_ruby & rails doc?

Aquila

1/11/2005 12:40:00 PM

Is there a place where I can find information on using mod_ruby? A single
stupid example will do, I just can't find anything...
I guess once I get mod_ruby working rails will work too? I don't find any
information on that combination either.

I'm anxious to start using rails!

you don't need modruby to use rails.

It will probably be my fault but I can't find any example on modruby.net? I
really can't find a complete script...

But if I prefer not to use CGI I read it's possible to use Rails with
mod_ruby. Or am I misinformed?

You can use it with mod_ruby. I think FastCGI is probably used more
(happens to be what I use as well) and is quite performant.

Using the mod_ruby gives web application more bags of tools that comes
with Apache, just like the mod_php. And also, it is easier to manage
since it is integrated with Apache.

Some have claimed that FastCGI is faster than mod_ruby, can anyone
validate these claims? Because I can hardly believe that CGI is faster
than the embedded interpreter.

mod_ruby uses one interpreter per Apache process, which means that apps
walk all over each other in the namespaces. At least for Rails, that's
not acceptable, so it's 1 app per Apache setup if you want mod_ruby.

FCGI is a much better setup for Rails. You don't fill up a ton of
Apache processes with your app (so apache processes serving static
files and images stay small) and you can have as many apps per apache
setup as you'd like.

I've found FCGI to be 10-15% faster in my tests with Rails.

I believe this is because FastCGI keeps one or more Ruby interpreters in
memory, rather than creating a new process on each Web request.

Bear in mind that with mod_ruby, all Web applications are sharing the
same interpreter, and the same object space.

Doesn't anyone use mod_ruby then? Does everyone use Rails? There must be
some example lying around somewhere...

Thanks for your help and ruby!

There's mod_ruby examples on:
http://www.modruby.net/e...
but perhaps
http://sean.chittenden.org/programming/ruby/mod_ruby/apachecon-2002/mod_ruby_...
would be more useful.

I have been using rails with mod_ruby, but have been getting some
transient errors. I just switched to using mod_fastcgi, and so far it
seems to be both faster and error-free.

HTH,
Jeff

mod_ruby doesn't have to be used to create a webapp, you know :-) I use
mod_ruby to customize & extend Apache behaviour (e.g. custom URL
mapping, URL filtering, and flexible wrapped CGI execution). It's so
much easier and faster using Ruby to create Apache modules instead of C.

Oh and I use plain Ruby CGI and FastCGI too.

I don't understand it, you need some sort of layer on top of apache to use
server sided scripting with apache, and if you don't you can use webrick or
some other stand alone http server, right?

You are writing your own mod_filtering etc? That sounds really interesting.
Can I find your code somewhere?

> Oh and I use plain Ruby CGI and FastCGI too.
By plain Ruby CGI you mean Ruby on top of "regular" Apache CGI?
To end a message from a confused person: I do understand what you mean by
FastCGI...

Thanks for the information!
