What is Passenger? 

Passenger is a web server and application server, designed to be fast, robust and lightweight. It takes a lot of complexity out of deploying web apps, adds powerful enterprise-grade features that are useful in production, and makes administration much easier and less complex. Phusion Passenger supports Ruby, Python, Node.js and Meteor, and is being used by high-profile companies such as Apple, Pixar, New York Times, AirBnB, Juniper etc as well as over 350.000 websites.

Main features:

  • Simple configuration
    • Simultaneously run and manage all your Ruby, Node.js, Python, and Meteor apps, as well as APIs and microservices, on a single Passenger instance.
  • Consolidated overviews
    • Simplify your DevOps logistics by managing and monitoring multiple apps at once.
  • NGINX and Apache integration
    • Passenger’s installation process includes either NGINX or Apache installation to reduce work and moving parts on your end.
  • Supported technologies
    • RubyGem, APT and YUM packages; Puppet, Chef, and Ansible recipes; Docker integration; and more are available.

What's new in version 5.1.8?

  • APT Nginx package to 1.12.1
    • The APT Nginx package that was provided for older distributions (Ubuntu Xenial / Debian Jessie and below) was stuck at Nginx version 1.10.3 due to incompatibilities in the module set that those distributions use. Updated module versions have solved these issues, so we've upgraded the package to the latest stable Nginx (1.12.1).
  • Webpacker asset support
    • Passenger Standalone now automatically uses Nginx to serves static asset URLs that conform to the webpacker gem format.
  • Improved logging
    • Log format changed to be shorter and more informative. The new format significantly shortens the thread ID, and includes the message's (abbreviated) log level so that it's a lot easier to filter through messages.
  • Various fixes
    • Fixes a potential use-after-free bug when reporting usage data to the Phusion licensing server. This bug only occurs when Passenger Enterprise is running inside a container.
    • If configured to listen on a Unix domain socket, properly cleans up this socket on Nginx shutdown (a regression from 5.1.6).
    • Fixes the --max-requests option when using the builtin engine (a regression from 5.1.4).
