改名了，改名了！
原来叫 happycasts.net 太咬嘴了，现在叫 http://haoduoshipin.com 了。
ruby
rbenv install 2.1.3
mysql
sudo apt-get install mysql-server mysql-client libmysqlclient-dev
Installing Nginx & Passenger
Install Phusion's PGP key to verify packages
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7
Add HTTPS support to APT
sudo apt-get install apt-transport-https ca-certificates
Add the passenger repository. Note that this only works for Ubuntu 14.04. For other versions of Ubuntu, you have to add the appropriate repository according to Section 2.3.1 of this link.
sudo add-apt-repository 'deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main'
sudo apt-get update
Install nginx and passenger
sudo apt-get install nginx-extras passenger
Next, we need to update the Nginx configuration to point Passenger to the version of Ruby that we're using. You'll want to open up /etc/nginx/nginx.conf in your favorite editor,
sudo vim /etc/nginx/nginx.conf
find the following lines, and uncomment them:
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/bin/ruby;
update the second line to read:
passenger_ruby /home/deploy/.rbenv/shims/ruby;
config passenger
sudo rm /etc/nginx/sites-enabled/default
sudo ln -s /home/your_name/happycasts/config/nginx.conf /etc/nginx/conf.d/happycasts.conf
sudo service nginx restart
Install JavaScript Runtime
A JavaScript Runtime is needed for Asset Pipeline to work. Any runtime will do but Node.js is recommended.
sudo apt-get install nodejs
