Deployment 如何使用capistrano在rails服务器上运行脚本？

我已经编写了一个名为

mailman\u server

的脚本，使用

gem“mailman”

放在“script/mailman\u 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

它从我的帐户中提取所有电子邮件，然后我对它们进行处理

我的

deploy.rb

文件如下

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

我希望每次部署到服务器时都执行此脚本。此外，每当我部署代码时，我都需要停止这个脚本

我无法确定如何在服务器上使用capistrano启动或停止此脚本。

您可以尝试在启动时使用类似的内容保存进程的pid

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

并停止它与

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

但我认为您应该检查一下，它提供了在开发中运行作业的简便方法，并支持将作业导出到upstart或用于生产的inid.d脚本，所以您只需要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"

---

如何手动停止脚本？只需在处理过程中按Ctrl+C？如果是这种情况，最好添加另一个脚本来终止由

mailman_server

启动的进程，并在部署

调用它。@Prakash是的，我这样做了。因为我需要在服务器上运行该脚本，所以我使用了屏幕。
