Run rails server in development environment with SSL

rails_ssl.md

Sources:

• Using Thin for development (with SSL)
• Sử dụng SSl trong Rails

1. Create self-signed SSL certificate

cd
mkdir .ssl
cd .ssl

# enter localhost.ssl as Common Name
openssl req -new -newkey rsa:2048 -sha256 -days 365 -nodes -x509 -keyout localhost.key -out localhost.crt

2. Add localhost.ssl to /etc/hosts

echo "127.0.0.1 localhost.ssl" | sudo tee -a /etc/hosts

3. Modify config of Rails app

# config/environments/development.rb

config.force_ssl = true

# show server log like running server with 'rails s' command
logger           = ActiveSupport::Logger.new(STDOUT)
logger.formatter = config.log_formatter
config.logger    = ActiveSupport::TaggedLogging.new(logger)

4. Run server

thin start -p 3000 --ssl --ssl-key-file ~/.ssl/localhost.key --ssl-cert-file ~/.ssl/localhost.crt

5. Access web app with https protocol

Open browser and access https://localhost.ssl:3000/.
