------------------------------------------ deprec - Deployment Recipes for Capistrano ------------------------------------------ == Introduction The deprec  gem is a set of tasks for Capistrano . These tasks provide for the installation, configuration and control of system services. Deprec was created in 2006 by Mike Bailey to setup an environment for running Ruby on Rails web applications on Ubuntu dapper servers. Since then its uses have grown to installing mail, monitoring, high availability IP failover and other services. The tasks are run at the command line on your workstation and connect to remote servers via ssh to run commands and copy out files. Deprec-2.x is a complete rewrite of the project that achieves the following: - support for Capistrano 2 - support for more services (heartbeat, nagios, nginx, ntp, postfix, etc) - creation of a standard base set of task names - tasks are cleanly separated into namespaced units (one file per service) - service config files are stored locally to enable edits and version control - interactive prompting for missing config values One idea that is in the trash can is supporting other distros/OS's. While I got caught up in the excitement of The Big Rewrite I've decided I don't need it. If you want to deploy to something other than Ubuntu I suggest you look for other alternatives. Deprec and Capistrano are written in the Ruby programming language  however no knowledge of Ruby is required to use it. Users should be able to write new tasks and modify existing options without prior knowledge of Ruby. == Installation Deprec can be obtained from rubyforge and installed using rubygems. sudo gem install deprec # installs deprec and dependancies cap depify . # creates ~/.caprc which you may edit cap -T # should list lots of deprec tasks The .caprc file is loaded every time you use Capistrano. It in turn loads the deprec tasks so you always have them available. Editing the .caprc file in your home directory allows you to specify the location of your ssh key and enable some other useful options (documented in the comments). You can also put tasks here that you want to always have access to. == Getting a Ruby on Rails app running on a fresh Ubuntu server This is still what brings people to deprec. You can install a full Rails stack and get multiple apps running on it in much less time than it would take to do it manually. Think an hour vs. a weekend. (The irony is I'm up writing this on a Saturday night.) export HOSTS=<target.host.name> # Install Rails stack cap deprec:rails:install_rails_stack # Install mysql (if it's running on the same box) cap deprec:mysql:install cap deprec:mysql:config_gen cap deprec:mysql:config # Install your Rails app cap deploy:setup cap deploy cap deprec:db:create cap deprec:db:migrate cap deprec:nginx:restart cap deprec:mongrel:restart You can find documentation on the deprec site. http://www.deprec.org/ == Installing other things I plan to document other things I use deprec for on http://www.deprec.org/. Feel free to poke around and see what's there. I use deprec to provision and manage servers so you might find some things in there I haven't documented. Lucky you. == Disclaimer The tasks run commands that may make changes to your workstation and remote server. You are advised to read the source and use at your own risk. == Credits Deprec is written and maintained by Mike Bailey <firstname.lastname@example.org>. More about me here: [http://mike.bailey.net.au/] Deprec was inspired and uses the brilliantly executed Capistrano. Thanks Jamis! This gem includes a modified copy of Neil Wilson's very useful vmbuilder_plugins gem. == Thanks Eric Harris-Braun: great testing, bug reports and suggestions Gus Gollings: helped restore www.deprec.org Craig Ambrose: testing, documentation and beer == License Deprec is licenced under the GPL.
