Just a FYI I changed the script to install Ruby to /usr/local thanks to some input from a Github user. Also people are forking it and setting it up to install RVM so feel free to check those out as well!

Re: Get Ruby and Rails running on Ubuntu with one command
#22Some comments & questions from someone who's worked on something similar:
-What's extglob used here for? I don't see any regexes.
-What are libffi-dev and libyaml-dev for? I assume some common gems depend on them. If so, which? (I'm just getting into Rails.)
-Git in the Maverick repos is old (1.7.1, which was released in April). Installing it from source is probably a better idea.
-You should probably use RVM to install Ruby, since its 1.9.2-head target won't require you to keep updating your script with 1.9.2's patchlevel.
-In my rails3.sh (which I should really publish), I didn't need to `gem install bundler` in order for `bundle install` to work. Probably because `rails` depends on `bundler`.
-That sudo check is neat, and I'd like to lift it; what's this script's license?

extglob is in there for future improvements. I plan to make it robust enough to accept parameters in the future.
When building Ruby the output complained about some missing deps. libffi-dev and libyaml-dev made Ruby stop complaining about them :)
Bundler is installed on the system because you don't have to install Rails on the system. You could simply put Ruby on there, install bundler then when you upload your app and run "bundle" it will pull down Rails and any gems your app depends on. Having Bundler available on the system is needed if you don't install the Rails gem system wide.
Use the script however you see fit and feel free to take from it what you like :)

#24Oblig. bash.org, http://www.bash.org/?464385 it only takes three commands to install Gentoo cfdisk /dev/hda && mkfs.xfs /dev/hda1 && mount /dev/hda1 /mnt/gentoo/ && chroot /mnt/gentoo/ && env-update && . /etc/profile && emerge sync && cd /usr/portage && scripts/bootsrap.sh && emerge system && emerge vim && vi /etc/fstab && emerge gentoo-dev-sources && cd /usr/src/linux && make menuconfig && make install modules_insta…
haha updated to read "A setup script to get Ruby and Rails running on Ubuntu server in one line". The first draft of the script was one command originally.
Re: Get Ruby and Rails running on Ubuntu with one command
#25Nice! It'd be nicer if it used RVM, though. Might try rolling my own.
If anyone else wants to try, or is otherwise interested, I wrote a step-by-step guide to getting Rails on Ubuntu with RVM: http://news.ycombinator.com/item?id=2113525

I believe your earlier version already was installing to /usr/local. You've just made it explicit. Most configuration scripts accept a --prefix option, but default to /usr/local if you omit the option. I'm pretty sure that Ruby works that way, and it's exceedingly common. (Not that the explicitness isn't a good idea. You don't want to rely on a default without being sure.)
Follow-up: partial output of ./configure --help in a Ruby source directory:
> By default, `make install' will install all the files in `/usr/local/bin', `/usr/local/lib' etc. You can specify an installation prefix other than `/usr/local' using `--prefix', for instance `--prefix=$HOME'.

#27Note to the wise: do not run this on a production machine unless you understand the full consequences of what the script is doing.
This is great for starting out a new machine and getting things setup, but running the update and upgrade commands without consideration of what's being updated could cause a lot of headaches if any existing sites running on the server have dependencies that are botched by the upgrade.

The README advises to run on a fresh install. Install Ubuntu, run railsready, have fun :)
Re: Get Ruby and Rails running on Ubuntu with one command
#29This strikes me as no easier than rvm, but less clean (installations go to /usr/local, no easy way to switch between various ruby interpreters or gemsets, harder to uninstall, etc.). Why not just do this? 1) Update whatever requirements you need via APT tool of choice. 2) Install rvm 3) Install ruby-1.9 using rvm 4) gem install rails 5) Write great rails app.
Hmm, maybe putting together a oneliner for that would help a lot of people. Added to my todo list.

I don't understand the point of using a one-liner vs just doing it in a process and getting an understanding of whats going on at each step.
