How to setup Ruby and RubyGems on CentOS?

I have a CentOS 5.5 (64-bit server)

I'd like to install Ruby 1.8.7 (current patch level) and RubyGems

What's the best way to go about this?

disclaimer: I'm a CentOS noob


You can install it with default yum install -y ruby ruby-devel rubygems

Other way is to compile it by yourself

Ruby

wget http://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7-p302.tar.gz
tar -zxvf ruby-1.8.7-p302.tar.gz
cd ruby-1.8.7-p302
./configure --with-openssl-dir=/usr/lib/openssl
make
make install

Rubygems

wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.7.tgz
tar -zxvf rubygems-1.3.7.tgz
cd rubygems-1.3.7
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

Check if installed

ruby -v
gem -v
