The bitterest tears shed over graves are for words left unsaid and deeds left undone.

How to develop Sinatra project


Add the application entry

Sinatra is a rack-based application like Rails. Before deployment, add a config.ru file to the root of the Sinatra project with the following content:

require "myapp" # Main file of your project
run Sinatra::Application # If it is a defined subclass, use the name of the class you defined directly

After that, the process is basically the same as deploying rails, using Nginx + Passenger as an example.

Install Nginx and Passenger

gem install passenger
sudo passenger-install-nginx-module

Adding Nginx to services and self-start

wget https://raw.github.com/gist/1548664/53f6d7ccb9dfc82a50c95e9f6e2e60dc59e4c2fb/nginx
sudo cp nginx /etc/init.d/
sudo chmod +x /etc/init.d/nginx
sudo update-rc.d nginx defaults

Config Nginx(/opt/nginx/conf/nginx.conf)

server {
        listen       3000;
        server_name  localhost;

        location / {
        root /srv/my_app/public;
        passenger_enabled on;
