Ubuntu下搭建Ruby On Rails開發環境

Ubuntu 12.04 + Ruby 2.0 + Rails 3.2.13

1、安裝系統需要的包

$ sudo apt-get install -y build-essential openssl curl libcurl3-dev libreadline6 libreadline6-dev git zlib1g zlib1g-dev libssl-dev libyaml-dev libxml2-dev libxslt-dev autoconf automake libtool p_w_picpathmagick libmagickwand-dev libpcre3-dev libsqlite3-dev libmysql-ruby libmysqlclient-dev

2、安裝RVM

$ curl -L https://get.rvm.io | bash -s stable

安裝RVM成功后，
然后，載入 RVM 環境（新開 Termal 就不用這么做了，會自動重新載入的）

$ source ~/.rvm/scripts/rvm

檢查一下是否安裝正確

$ rvm -v
rvm 1.17.3 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

3、用RVM安裝Ruby環境

# 替換 Ruby 下載地址到國內淘寶鏡像服務器$ sed -i.bak 's!ftp.ruby-lang.org/pub/ruby!ruby.taobao.org/mirrors/ruby!' $rvm_path/config/db
# 安裝 readline 包$ rvm pkg install readline
# 安裝 Ruby 2.0.0$ rvm install 2.0.0 --with-readline-dir=$rvm_path/usr

4、設置Ruby版本

$ rvm 2.0.0 --default

測試是否正確

$ ruby -v
ruby 2.0.0p0 (2013-02-24 revision 39474)[x86_64-darwin12.3.0]
$ gem -v
2.0.0
$ gem source -r https://rubygems.org/
$ gem source -a http://ruby.taobao.org

5、安裝Rails環境

$ gem install bundler rails #或者gem install -v=3.2.13 rails

測試安裝是否正確

$ bundle -v
Bundler version 1.0
$ rails -v
Rails 3.2.13

6、安裝MySQL

$ sudo apt-get install mysql-server mysql-client //牢記安裝過程中輸入的密碼$ sudo apt-get install libmysql-ruby libmysqlclient-dev
$ gem install mysql2

查看Gem包 gem list
