下面开始安装Ruby
一、下载Ruby源码包
wget ftp://ftp.ruby-lang.org/pub/ruby/2.1/ruby-2.1.7.tar.gz
二、解压安装Ruby
tar zxvf ruby-2.1.7.tar.gz
./configure --disable-install-rdoc
make
make prefix=/usr/local install
三、安装Bundler Gem
由于AWS被墙无法使用，修改ruby的源为淘宝
gem sources --remove https://rubygems.org/
gem sources -a https://ruby.taobao.org/
gem sources -l
gem install bundler --no-doc
添加以下软连接，否则可能提示找不到
ln -s /usr/local/bin/ruby /usr/bin/ruby
ln -s /usr/local/bin/gem /usr/bin/gem
ln -s /usr/local/bin/bundle /usr/bin/bundle
四、查看验证
[root@test81 ~]# which ruby
#/usr/local/bin/ruby
[root@test81 ~]# which gem
#/usr/local/bin/gem
[root@test81 ~]# which bundle
#/usr/local/bin/bundle
[root@test81 ~]# ruby -v
#ruby 2.1.7p400 (2015-08-18 revision 51632) [x86_64-linux]
