本文測試通過環境

Ubuntu 12.04 Server，

服務器安裝測試于 Linode VPS （Ubuntu 12.04 LTS (GNU/Linux 3.4.2-x86_64-linode25 x86_64)。

配置 Ubuntu Server 系統

如果你是國內服務器，推薦修改網易的源

輸入 sudo vi /etc/apt/sources.list 將里面的內容替換成：

deb http://mirrors.163.com/ubuntu/ precise main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ precise main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse

然后更新一下:

$ sudo apt-get update

安裝必要的三方庫

$ sudo apt-get install -y wget vim build-essential openssl libreadline6 libreadline6-dev libmysqlclient-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libxml2-dev libxslt-dev libcurl4-openssl-dev autoconf automake libtool imagemagick libmagickwand-dev libpcre3-dev nodejs libpq-dev

安裝 Ruby, Rails 及相關

安裝 RVM

$ /curl -L https://get.rvm.io | bash -s stable $ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"' >>~/.bashrc $ source ~/.bashrc $ rvm -v

安裝 Ruby

如果你是國內服務器，推薦將 RVM 的安裝源替換成 Taobao 的鏡像服務器，這樣安裝能更快！

$ sed -i -e 's/ftp/.ruby-lang/.org//pub//ruby/ruby/.taobao/.org//mirrors//ruby/g' ~/.rvm/config/db

用 RVM 安裝 Ruby:

$ rvm pkg install readline openssl $ rvm install 2.0.0 $ rvm use 2.0.0 --default $ ruby -vruby 2.0.0p247

國內服務器推薦替換 RubyGems 的到淘寶鏡像:

$ gem sources --remove https://rubygems.org/ $ gem sources -a http://ruby.taobao.org/ $ gem sources -l *** CURRENT SOURCES *** http://ruby.taobao.org

安裝 Rails

$ gem install rails $ rails -vRails 4.0.0

安裝 MySQL 或其他數據庫
