Capistrano 1
Don’t use this for setting up a new account. It is very old, and won’t work on our newer servers. It also uses what we consider depreciated technology.

# DESCRIPTION
#
# This is a customized recipe for easily deploying lighttpd to PLANET ARGON.
# It takes the instructions from five different manuals and puts them into a Capistrano
# Recipe.
#
# For full details/more information, see:
# http://manuals.rubyonrails.com/read/book/17
# http://nubyonrails.com/pages/shovel
# http://www.lighttpd.net/documentation/configuration.html
# http://www.brandalism.com/articles/2006/02/09/setting-up-lighttpd-on-planet-argon
#
# To setup lighty, first edit this file for your primary PLANET ARGON account.
# Then run:
# rake remote:exec ACTION=setup_lighty
#
# This will create all the necessary config files for running lighttpd.
#
# DON'T USE DAEDALUS!
#
# From then, you can deploy your application to PLANET ARGON with Capistrano's standard
# rake deploy
#
# Or rollback with
# rake rollback
#
#############
# Set these variables to work with your PLANET ARGON Account
set :application, 'blog' # The one you are deploying.
set :user, "vu2000" # Your PA username
set :pa_primary_domain, 'railsfanboy.com'
set :pa_server_ip, "64.34.217.149" # The IP address of the machine which hosts your shared space
set :lighty_port, 808080808080 # The port given to you by PLANET ARGON for running lighttpd
set :repository, "http://dev.railsfanboy.com/svn/#{application}/trunk" # Your SVN URL
set :deploy_to, "/var/www/virtual/#{pa_primary_domain}/#{application}/rails"
#
#############
# By default, the source control module (scm) is set to "subversion". You can
# set it to any supported scm:
set :scm, :subversion
set :pa_home, "/home/#{user}"
# This is a HIGHLY SIMPLIFIED deployment recipe. If you are looking for something
# more sophisticated (e.g. using different machines for different roles), stop
# reading this and go to:
# http://manuals.rubyonrails.com/read/book/17

# Define tasks that run on all (or only some) of the machines. You can specify

# narrow the set of servers to a subset of a role by specifying options, which
# must match the options given for the servers to select (like :primary => true)

# a transaction (see below), AND it or a subsequent task fails.

# Tasks may take advantage of several different helper methods to interact
# with the remote server(s). These are:
#
# * run(command, options={}, &block): execute the given command on all servers
# associated with the current task, in parallel. The block, if given, should
# accept three parameters: the communication channel, a symbol identifying the
# type of stream (:err or :out), and the data. The block is invoked for all
# output from the command, allowing you to inspect output and act
# accordingly.
# * sudo(command, options={}, &block): same as run, but it executes the command
# via sudo.
# * delete(path, options={}): deletes the given file or directory from all
# associated servers. If :recursive => true is given in the options, the
# delete uses "rm -rf" instead of "rm -f".
# * put(buffer, path, options={}): creates or overwrites a file at "path" on
# all associated servers, populating it with the contents of "buffer". You
# can specify :mode as an integer value, which will be used to set the mode
# on the file.
# * render(template, options={}) or render(options={}): renders the given
# template and returns a string. Alternatively, if the :template key is given,
# it will be treated as the contents of the template to render. Any other keys
# are treated as local variables, which are made available to the (ERb)
# template.
desc "Demonstrates the various helper methods available to recipes."
task :helper_demo do
# "setup" is a standard task which sets up the directory structure on the
# remote servers. It is a good idea to run the "setup" task at least once
# at the beginning of your app's lifetime (it is non-destructive).
