RExec

RExec stands for Remote Execute and provides support for executing processes both locally and remotely. It provides a number of different tools to assist with running Ruby code:

• A framework to send Ruby code to a remote server for execution.
• A framework for writing command line daemons (i.e. start, restart, stop, status).
• A comprehensive Task class for launching tasks, managing input and output, exit status, etc.
• Basic privilege management code for changing the processes owner.
• A bunch of helpers for various different things (such as reading a file backwards).
• daemon-exec executable for running regular shell tasks in the background.

For more information please see the project page.

Installation

Add this line to your application's Gemfile:

gem 'rexec'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rexec

Usage

Comprehensive process management

RExec::Task provides a comprehensive wrapper for low level process execution and life-cycle management. You can easy spawn new child processes, background processes and execute Ruby code in a child instance.

Light weight bi-directional communication

The RExec::Connection provides a simple process based API for communicating with distant instances of Ruby. These can either be local or remote, such as over SSH.

Simple daemonization

The RExec::Daemon module provides the foundation to develop long-running background processes. Simply create a daemon class which inherits from RExec::Daemon::Base and you can have a fully featured background daemon with the standard command line interface, e.g. start, restart, status and stop.

Along with this, a executable is included called daemon-exec which allows for any standard shell script to be run as a background process.
