thin's Introduction

Thin

A small and fast Ruby web server

Installation

gem install thin

Or add thin to your Gemfile:

gem 'thin'

Usage

A +thin+ script offers an easy way to start your Rack application:

thin start

Browse the example directory for sample applications.

Usage with Rails Action Cable

To use Thin with Action Cable, add the following to your Gemfile:

gem 'faye-websocket'
gem 'thin' # If not already done

Create a config/initializers/thin_action_cable.rb:

Rails.application.config.action_cable.use_faye = true
Faye::WebSocket.load_adapter 'thin'

CLI

Use a rackup (config.ru) file and bind to localhost port 8080:

thin -R config.ru -a 127.0.0.1 -p 8080 start

Store the server process ID, log to a file and daemonize:

thin -p 9292 -P tmp/pids/thin.pid -l logs/thin.log -d start

Thin is quite flexible in that many options can be specified at the command line (see thin -h for more).

Configuration files

You can create a configuration file using thin config -C config/thin.yml.

You can then use it with all commands, such as: thin start -C config/thin.yml.

Here is an example config file:

--- 
user: www-data
group: www-data
pid: tmp/pids/thin.pid

max_persistent_conns: 512
servers: 1
threaded: true
no-epoll: true
daemonize: true
socket: tmp/sockets/thin.sock
