Hi,

I just installed ruby on my ubuntu, I use this following command to install
ruby:

# sudo apt-get install ruby1.9.1-full

After installation succeeded, I don't know what are the next step to begin
developing ruby, I from PHP language and I want to try to learn ruby.

oh ya, the command above as I know is installing ruby CLI like php CLI,
right?
 or installing all environment like (php,apache) so I can beginning to learn
make some web application with ruby and I can debug with my browser.

Please put me right in this new experience :).


Thanks for all ruby gurus :)

Hello Didin ~

Look at rvm:

https://rvm.beginrescueend.com/

ruby has a package manager built in called gem

it also has it's own repl called irb.

to install rails use gem like so:

% gem install rails

to learn ruby interactivly use irb:

% irb
>> "Hello, World!".reverse
 => "!dlroW ,olleH"

Hope this helps

~Stu

Ruby on Rails is a full stack web framework:

http://rubyonrails.org/

I believe that is what your looking for.

If you don't need a framework look at other projects like
http://www.sinatrarb.com/

I think that some PHP ideas don't translate directly to Ruby (I don't know
PHP, so this is just my impression). Ruby is a general purpose language, so
it is used for all sorts of things and isn't hooked up to the internet by
default (for example, most of the things I use Ruby for don't have anything
to do with web applications), and it isn't embedded in a template by default
either (PHP might not be, but that's just how I've always seen it).

-----

I think the easiest solution will be this:

$ gem install sinatra shotgun --no-ri --no-rdoc

(that will install the libraries locally, if that doesn't work, you will
need to either edit your path or use sudo)

Then create a file hw.rb that looks like this:

require 'sinatra'
get '/' do
  "hello, world!"
end

That uses the sinatra web micro-framework to create a web application.

Then, run that application with $ shotgun hw.rb

Sinatra will know how to serve itself up, and shotgun will know how to
reload the file every time you make a request, this allows you to save your
document and reload your page without having to stop and start your server.

Finally, go to (http://localhost:9393/) in your browser. If everything is
working correctly, it will say "hello world"

-----

From there, check out (http://www.sinatrarb.com/intro.html) which will help
you make Sinatra do interesting things for you. I also recommend this great
screencast (http://peepcode.com/products/sinatra), where they'll walk
through a lot of the features and write an application with a database back
end.

You'll need to learn the Ruby language as well, though. I'm not sure what
people consider good resources for that, you'll have to ask around. If
you're comfortable with programming, you could take a look at Ruby
Kickstart, a curriculum I wrote to teach my friends Ruby (
https://github.com/JoshCheek/ruby-kickstart).

Once you are comfortable with all of that, you should be primed for Ruby on
Rails, :) If that is where you're wanting to head, then I recommend
http://guides.rubyonrails.org/ as the best resource I've seen for learning
Rails.

Anyway, welcome to Ruby :)

This depends on how comfortable you are with setting up Apache and what 
direction you want to go in.

If you are very comfortable with Apache, then install mod_ruby and you 
can make pages using <% ruby_code_here %> (instead of <? php_code_here 
?>). This is, however, considered a rather antiquated way of developing 
web applications (but do it anyway if that is how you want to get started).

If you are thinking of writing full-fledged web applications, then you 
may wish to try one of the many web frameworks suggested in other replies.

To install rails you will need sqlite3 installed( though you can use
any db supported it's just default)

Here is a console walk through to get you started. First a summer of
commands used:

-> % history

   1  gem install rails
   2  rehash
   3  rails new my_web_app
   4  cd my_web_app
   5  bundle install
   6  rails server

(1) I install the rails gem. (2) I rehash for zsh. (3) I create my new
application template with the rails new generator. (4) I change to my
new application's directory. (5) run the bundler command to find any
gems that may be not installed (i.e. sqlite3). (6) start the server.

from there you can open your browser and see the welcome screen at
http://0.0.0.0:3000 or localhost:3000

Further instructions can be found at the Rails guide link on that page.

Here is a more verbose output from my console:

-> %  gem install rails

after that I try to install sqllite3
with sudo apt-get install sqlite3 and installed,

I try to restart server rails, but it doesn't change and keep in producing
this error.
so I try to do

# sudo gem install sqlite3
but it was error:

Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.


Anyone, can help me?

Thank you :)

You need to install the sqlite3-dev package via apt-get, then try 
installing the gem again.

This depends on how comfortable you are with setting up Apache and what 
direction you want to go in.

If you are very comfortable with Apache, then install mod_ruby and you 
can make pages using <% ruby_code_here %> (instead of <? php_code_here 
?>). This is, however, considered a rather antiquated way of developing 
web applications (but do it anyway if that is how you want to get started).

If you are thinking of writing full-fledged web applications, then you 
may wish to try one of the many web frameworks suggested in other replies.

Thank you for precious answer, I feel increased in my knowledge :).

so, I get that ruby is different with PHP,
as we know PHP is more inclined to web development purpose, but ruby is
general purpose not inclined to web, but can be used to webdevelopment with
add some application (rubyonrails or sinatra or etc), is it what I say
right?

firstly, I think that rubyonrails is similiar with Zend framework (one of
PHP framework).

Thanks for all :), maybe I will try use rubyonrails

Yes.  Josh Cheek described the difference between php and ruby 
accurately.

Yes, that's correct.

Some more information: just like with php, you don't need to use a 
bloated "framework" to use ruby on "the server side"(=for web pages). 
Ruby can use the "cgi gateway" that your server probably provides.  In 
fact, it is probably a good excercise to write at least one ruby cgi 
program just to see how it works.  Here is a tutorial:

Thanks Josh, Justin and 7stud :-)
 Rails installed fine now, I use ruby 1.8,

You want to get a text editor that does automatic line indenting.  Then 
you create a new file, enter some ruby code, and save the file with a 
rb extension.  Then at the command line type:

ruby my_program.rb

and you will see any output your program produces.

I would use ruby 1.9.2.  There are enough differences that you should 
learn the latest ruby.
