Installing Ruby & gem

Just a memo for myself.

Environment

• CentOS 5.8 (Final)

Installing ruby 2.1.2

# cd /usr/local/src
# wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz
# tar xvfz ruby-2.1.2.tar.gz
# rm ruby-2.1.2.tar.gz
# cd ruby-2.1.2
# ./configure
# make; make install

Installing gem

# wget http://production.cf.rubygems.org/rubygems/rubygems-2.2.2.zip
# unzip rubygems-2.2.2.zip
# cd rubygems-2.2.2
# ruby setup.rb

That’s all.
