Ruby编程语言
Ruby,一种为简单快捷的面向对象编程(面向对象程序设计)而创的脚本语言,在20世纪90年代由日本人松本行弘开发,遵守GPL协议和Ruby License。它的灵感与特性来自于 Perl、Smalltalk、Eiffel、Ada以及 Lisp 语言。
LINUX操作系统: CentOS6.3 64bit
Ruby: ruby-2.0.0-p247
一.安装开发包(使用默认CENTOS更新源)
# yum install openssl* openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel
二.关闭iptables和SELINUX
# service iptables stop
# setenforce 0
# vi /etc/sysconfig/selinux
---------------
SELINUX=disabled
---------------
三.安装Ruby
# wget http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz
# tar zxvf ruby-2.0.0-p247.tar.gz
# cd ruby-2.0.0-p247
# ./configure --enable-shared --enable-pthread --prefix=/usr/local/ruby
# make && make install
ossl_pkey_ec.c:815: error: ‘EC_GROUP_new_curve_GF2m' undeclared (first use in this function)

详见:https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808
解决方法:
# cd ruby-2.0.0-p247
# wget --no-check-certificate https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/ext/openssl/ossl_pkey_ec.c
# wget --no-check-certificate https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/test/openssl/test_pkey_ec.rb
# mv ext/openssl/ossl_pkey_ec.c ext/openssl/ossl_pkey_ec.c.bak
# cp ossl_pkey_ec.c ext/openssl/
# mv test/openssl/test_pkey_ec.rb test/openssl/test_pkey_ec.rb.bak
# cp test_pkey_ec.rb test/openssl/
# make && make install
四.将ruby命令集加入系统环境变量
# echo "PATH=$PATH:/usr/local/ruby/bin;export PATH" >> /etc/profile
# source /etc/profile
五.检查ruby版本
# ruby -v
