Cheat Sheet - what do you need for Ruby on Rails?

For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

Here is a "cheat sheet" of the commands you might use to install Ruby, then Gems, then Rails, then get your first application and server running.

1. Ruby

tar xf ruby-1.9.1-p376.tar.gz

cd ruby-1.9.1-p376/

./configure

make

make install

Check installation:

[root@easterton ruby-1.9.1-p376]# ruby -v

ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]

[root@easterton ruby-1.9.1-p376]#

2. Ruby Gems

RubyGems is a sophisticated package manager for Ruby.
See http://docs.rubygems.org/ ...
Set up gems once you've installed Ruby via:

ruby setup.rb

3. Rails

gem install rails

4. Create a framework for your first application

rails path/to/your/new/application

5. Start the server

cd path/to/your/new/application

ruby script/server

Check installation:

Browse to http://localhost:3000/

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
