我不知道什么是错误时用来做工精细的源泉！
这是我的帽子文件
load 'deploy'
# Uncomment if you are using Rails' asset pipeline
# load 'deploy/assets'
Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy' # remove this line to skip loading any of the default tasks
load 'deploy/assets'
task :search_libs, :hosts => "mysitename.com" do
run "ls -x1 /usr/lib | grep -i xml"
end
，这是我的部署文件
require "bundler/capistrano"
default_run_options[:pty] = true
set :user, 'myname'
set :domain, 'mysitename.com'
set :application, 'mysitename'
set :repository, "#{user}@#{domain}:git/#{application}.git"
set :deploy_to, "/home/#{user}/#{domain}"
set :deploy_via, :remote_cache
set :scm, 'git'
set :branch, 'master'
set :git_shallow_clone, 1
set :scm_verbose, true
set :use_sudo, false
server domain, :app, :web
role :db, domain, :primary => true
namespace :deploy do
task :restart do
run "touch #{current_path}/tmp/restart.txt"
end
desc "reload the database with seed data"
task :seed do
run "cd #{current_path}; bundle exec rake db:seed RAILS_ENV=#{rails_env}"
end
end
它值得一提的是，当我ssh到我的远程服务器，并执行
cd /home/ssddff/mysitename.com/releases/20120609034922 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile
它无误地工作！
