• 警告：請絕對不要跳著裝！*

系統套件

進行 Ubuntu 系統更新 / 安裝 MySQL

 > sudo apt-get update
 > sudo apt-get upgrade
 > sudo apt-get install git
 > sudo apt-get install mysql-server libmysqlclient15-dev
 > sudo apt-get install curl
 > sudo apt-get install build-essential zlib1g-dev libssl-dev libreadline5-dev

#安裝 RVM 與 REE

安裝 RVM ( Ruby Version Manager )

• 請注意，無論如何都不要使用 root 身分安裝 RVM。後果自負！*

> bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
> echo "[[ -s $HOME/.rvm/scripts/rvm ]] && source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile && . ~/.bash_profile
> source ~/.bash_profile

接著編輯 .bashrc 加上 source ~/.bash_profile

安裝 REE ( Ruby Enterprise Edition )

 > rvm install ree
 > rvm ree --default 

• install libbuilder

sudo apt-get install libbuilder-ruby

安裝 Rails

首先需先安裝 libbuilder

  > sudo apt-get install libbuilder-ruby

接著才是安裝 Rails

> gem install rails -v=3.0.7
> gem install mysql

安裝 Passenger

> gem install passenger

• Install CURL with SSL

> sudo apt-get install libcurl4-openssl-dev

• Install apache

> sudo apt-get install apache2
> sudo apt-get install apache2-prefork-dev

• Install Passenger on Apache

passenger-install-apache2-module 

• sudo vim /etc/apache2/mods-enabled/mod_rails.conf

LoadModule passenger_module /home/xdite/.rvm/gems/ree-1.8.7-2011.03/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
PassengerRoot /home/xdite/.rvm/gems/ree-1.8.7-2011.03/gems/passenger-3.0.7
PassengerRuby /home/xdite/.rvm/wrappers/ree-1.8.7-2011.03/ruby

• sudo vim /etc/apache2/sites-enabled/forum.local.conf

 <VirtualHost *:80>
    ServerName forum.local 
    DocumentRoot /home/xdite/projects/forum/public    
    <Directory /home/xdite/projects/forum/public>
       AllowOverride all             
       Options -MultiViews          
    </Directory>
 </VirtualHost>

• sudo vim /etc/hosts

127.0.0.1  forum.local

$ mkdir -p ~/projects/
$ cd ~/projects/
$ rails new forum

• Open http://forum.local

• 如果你偏好 nginx solution 可以參考 https://github.com/jnstq/rails-nginx-passenger-ubuntu # 不過請注意這是 for production。local 開發建議使用 rvm

• install rmagick

# If you already installed imagemagick from apt-get
sudo apt-get remove imagemagick

sudo apt-get install libperl-dev gcc libjpeg62-dev libbz2-dev libtiff4-dev libwmf-dev libz-dev libpng12-dev libx11-dev libxt-dev libxext-dev libxml2-dev libfreetype6-dev liblcms1-dev libexif-dev perl libjasper-dev libltdl3-dev graphviz gs-gpl pkg-config

# Download source
wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz

tar zxvf ImageMagick.tar.gz
cd ImageMagick-*
./configure
make
sudo make install

gem install rmagick
