CentOS 6.3下編譯安裝Ruby 2.0的過程詳解

LINUX作業系統: CentOS6.3 64bit
Ruby: ruby-2.0.0-p247
一.安裝開發包(使用預設CENTOS更新源):

代碼如下	複製代碼
# yum install openssl* openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel

二.關閉iptables和SELINUX

代碼如下	複製代碼
# service iptables stop # setenforce 0 # vi /etc/sysconfig/selinux --------------- SELINUX=disabled

---------------
三.安裝Ruby

代碼如下	複製代碼
# wget http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz # tar zxvf ruby-2.0.0-p247 # 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)

google後找到官方的一個解決補丁，也就是替換兩個ssl庫檔案，附件為該補丁檔案打包下載地址
詳見：https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808
解決方案：

代碼如下

複製代碼

# cd ruby-2.0.0-p247 # wget https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/ext/openssl/ossl_pkey_ec.c # wget 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/

重新編譯：

代碼如下	複製代碼
# make && make install

四.將ruby命令集加入系統內容變數

代碼如下	複製代碼
# echo "PATH=$PATH:/usr/local/ruby/bin;export PATH" >> /etc/profile # source /etc/profile

五.檢查ruby版本

代碼如下	複製代碼
# ruby -v —————————————————————————— ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux] —————————————————————————— # gem --version —————————————————————————— 2.0.3 www.111cn.net —————————————————————————— # irb —————————————————————————— irb(main):001:0> 3+5 => 8 irb(main):002:0> puts "hello world!" hello world!
