我写了一个名为mailman_serverusing的脚本，gem "mailman"放在'script/mailman_server'中

    #!/usr/bin/env ruby
    require "rubygems"
    require "bundler/setup"
    require "mailman"

    #Mailman.config.logger = Logger.new("log/mailman.log")
    Mailman.config.poll_interval = 3
    Mailman.config.pop3 = {
      server: 'server', port: 110,
      username: "loginid",
      password: "password"
    }

    Mailman::Application.run do
      default do
        p "Found a new message"
        # 'perform some action here'
        end
    end

它从我的帐户中获取所有电子邮件，然后我对它们进行处理。

我有我的deploy.rb文件

set :stages, %w(production)     #various environments
load "deploy/assets"                    #precompile all the css, js and images... before deployment..
require "bundler/capistrano"            # install all the new missing plugins...
require 'delayed/recipes'               # load this for delayed job..
require 'capistrano/ext/multistage'     # deploy on all the servers..
require "rvm/capistrano"                # if you are using rvm on your server..
require './config/boot'           
require 'airbrake/capistrano'           # using airbrake in your application for crash notifications..

set :delayed_job_args, "-n 2"            # number of delayed job workers 


before "deploy:assets:symlink", "deploy:copy_database_file"
before "deploy:update_code",  "delayed_job:stop"  # stop the previous deployed job workers...
after "deploy:start",   "delayed_job:start" #start the delayed job 
after "deploy:restart", "delayed_job:restart" # restart it..
after "deploy:update", "deploy:cleanup" #clean up temp files etc.
set :rvm_ruby_string, '1.9.3'             # ruby version you are using...
set :rvm_type, :user

server "my_server_ip", :app, :web, :db, :primary => true 

set(:application) { "my_application_name" }
set (:deploy_to) { "/home/user/#{application}/#{stage}" }
set :user, 'user'
set :keep_releases, 3
set :repository, "git@bitbucket.org:my_random_git_repo_url"
set :use_sudo, false
set :scm, :git
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
set :deploy_via, :remote_cache
set :git_shallow_clone, 1
set :git_enable_submodules, 1

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end
  task :copy_database_file do
    run "ln -sf #{shared_path}/database.yml #{release_path}/config/database.yml"
  end
end

每次部署到服务器时，我都想执行这个脚本。此外，每当我部署代码时，我都需要停止此脚本。

我无法弄清楚我们如何在服务器上使用 capistrano 启动或停止此脚本。

您可以尝试以这样的方式开始保存进程的 pid

run "cd #{deploy_to}/current; ./script/mailman_server &; echo &! > /var/run/mailman_server.pid" #untested

并停止它

run "kill `cat /var/run/mailman_server.pid`;  rm /var/run/mailman_server.pid"

但是我认为您应该查看Foreman，它提供了在开发中运行作业的便捷方式，并支持将您的作业导出到 upstart 或 inid.d 脚本以进行生产，因此您只需启动或停止相应的服务

run "sudo /etc/init.d/mailman_server start"
run "sudo /etc/init.d/mailman_server stop"
