多个服务器上的Capifony Doctrine Database迁移

标签： ruby-on-rails symfony doctrine capistrano capifony

我正在尝试使用capifony在多台服务器上运行symfony doctrine迁移，但它似乎只在一台服务器上执行迁移。例如： 这就是我设置服务器地址的方式：

role :web,        "192.168.56.102","192.168.56.103"                         # Your HTTP server, Apache/etc
role :app,        "192.168.56.102","192.168.56.103", :primary => true       # This may be the same as your `Web` server

迁移仅在第一台服务器上执行，尽管两者都进行了代码部署。

这是我的部署脚本： 

#### Basic Deploying Script Config ####
set :application, "eConnect"
###set :domain,      "192.168.56.102"
set :user,   "vagrant"
set :use_sudo,  false
set :deploy_to,   "/var/www/SchoolEconnectDeployment"
set :app_path,    "app"

set :repository, "."
set :local_repository, "."
set :deploy_via,  :copy
set :scm,         :mercurial
# Or: `accurev`, `bzr`, `cvs`, `darcs`, `subversion`, `mercurial`, `perforce`, or `none`

set :model_manager, "doctrine"
set :interactive_mode, false
# Or: `propel`

role :web,        "192.168.56.102","192.168.56.103"                         # Your HTTP server, Apache/etc
role :app,        "192.168.56.102","192.168.56.103", :primary => true       # This may be the same as your `Web` server
set :copy_vendors, true
set :cache_warmup, false
set  :keep_releases,  3
set :shared_children, %w()

正如你所看到的，我必须做我自己的迁移功能，这个功能略有不同（没有那么不同的硬编码路径）。

我到处寻找，但找不到与我的问题相关的任何内容。

如果没有解决方案，我想知道如何在循环中调用任务并为其提供我想在部署脚本中编写的任何参数。我对红宝石很新，所以你知道。

P.S：我也尝试过多阶段方法，但没有任何方法可以帮助我。 我将不胜感激任何帮助。 非常感谢。

编辑：

我一直试图找到一个我一直在尝试的解决方法：

before "deploy:move_latest_release" do 
 machine_info = ['192.168.56.102','192.168.56.103']
    machine_info.each do |value| 


        role :db,        "#{value}", :primary => true       
        puts "#{value}".red
        deploy.econnect_migrate
    end 
    print " --> Moving the latest version to the correct Destination ........"
    start_spinner()
end

循环工作正常，但角色：db不会改变。

我也试过这个

cap HOSTS=192.168.56.102,192.168.56.103 deploy:econnect_migrate

仍然是同一个问题。
