安装zlib,不然gem install rails的时候可能会报错
rpm -ivh zlib-1.2.3-3.x86_64.rpm
rpm -ivh zlib-devel-1.2.3-3.x86_64.rpm
安装ruby1.86
wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-p111.tar.gz
tar zxvf ruby-1.8.6*.tar.gz
cd ruby-1.8.6*
./configure
make
make install
安装gem
wget http://rubyforge.org/frs/download.php/29548/rubygems-1.0.1.tgz
tar zxvf rubygem*.tgz
cd rubygem*
ruby setup.rb
查看能否加载 ‘zlib’
irb
require 'zlib'
如果显示 true
则可继续这个安装之旅，反之相尝试一下下面的解决方法
不能加载zlib，可尝一下安装
wget http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz
tar xzvf ruby-zlib-0.6.0.tar.gz
cd ruby-zlib-0.6.0
ruby extconf.rb
make
sudo make install
安装libopenssl-devel
rpm -ivh e2fsprogs-devel-1.39-10.e15.x86_64.rpm
rpm -ivh keyutils-libs-devel-1.2-1.e15.x86_64.rpm
rpm -ivh libsepol-devel-1.15.2-1.e15.x86_64.rpm
rpm -ivh libselinux-devel-1.33.4-4.e15.x86_64.rpm
rpm -ivh krb5-devel-1.6.1-17.e15.x86_64.rpm
rpm -ivh openssl-devel-0.9.8b-8.3.e15_0.2.x86_64.rpm
进入到ruby源代码的ext/openssl下，执行
ruby extconf.rb
make
make install
进入到irb，
require 'openssl'
如果返回true则成功。
安装Rail
gem install rails --include-dependencies
