ruby 编译安装，gem国内源ruby.taobao.org

centos6.6final

一.安装依赖包(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

国内用淘宝的源快：https://ruby.taobao.org/

#wget https://ruby.taobao.org/mirrors/ruby/ruby-2.2.0.tar.gz 或者官方下载源码包 https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.2.0.tar.gz

#tar zxvf ruby-2.3.0.tar.gz

#cd ruby-2.3.0

#./configure --prefix=/opt /ruby

#make

#make install

#ln -s /opt/ruby/bin/* /usr/bin/ 【如安装在/usr/local下，无需要做软链接和环境变量添加】

（将ruby命令集加入系统环境变量

# echo "PATH=$PATH:/opt/ruby/bin;export PATH" >> /etc/profile

# source /etc/profile

）

#gem sources --remove https://rubygems.org/

#gem sources -a https://ruby.taobao.org/

#gem sources -l

#gem update --system
