CentOS 6.3下编译安装Ruby 2.0

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

编译时报错

ossl_pkey_ec.c:815: error: ‘EC_GROUP_new_curve_GF2m’ undeclared (first use in this function)

google后找到官方的一个解决补丁，也就是替换两个ssl库文件，附件为该补丁文件打包下载地址

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/

重新编译：

# 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

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

# gem --version

# irb

irb(main):001:0> 3+5

=> 8

irb(main):002:0> puts "hello world!"

hello world!
