有没有办法使用capistrano（或类似）远程交互rails控制台 [英] Is there a way to use capistrano (or similar) to remotely interact with rails console

问题描述

我很喜欢capistrano如何简化我的部署工作流程，但通常情况下，推送更改会遇到我需要登录服务器通过控制台进行故障排除的问题。

有没有办法使用capistrano或其他远程管理工具与本地终端服务器上的rails控制台进行交互？

**更新： / p>

cap shell似乎很有前途，但是当您尝试启动控制台时它会挂起：

  cap> cd / path / to / application / current 
 cap> pwd 
 ** [out :: application.com] / path / to / application / current 
 cap> rails c production 
 ** [out :: application.com]加载生产环境（Rails 3.0.0）
 ** [out :: application.com]切换到检查模式。 
  

如果你知道一个解决方法，这将是巨大的

解决方案

我发现相当不错的解决方案基于 https://github.com/codesnik/rails-recipes/blob/master/lib/rails-recipes/console.rb

  desc远程控制台
 task：console，：roles => ：app do 
 env = stage || production
 server = find_servers（：roles => [：app]）。first 
 run_with_tty服务器，％W（./script/rails console＃{env}）
 end 
 
 desc远程dbconsole
任务：dbconsole，：roles => ：app do 
 env = stage || production
 server = find_servers（：roles => [：app]）。first 
 run_with_tty服务器，％W（./script/rails dbconsole＃{env}）
 end 
 
 def run_with_tty（server，cmd）
＃看起来像总pizdets 
 command = [] 
命令+ =％W（ssh -t＃{gateway} -l ＃{self [：gateway_user] || self [：user]}）if self [：gateway] 
命令+ =％W（ssh -t）
命令+ =％W server.port}）如果server.port 
命令+ =％W（-l＃{user}＃{server.host}）
命令+ =％W（cd＃{current_path}）
＃如果通过double ssh 
命令+ = [self [：gateway]？ '\& \&'：'&&'] 
 command + = Array（cmd）
 system * command 
 end 
  

I'm loving how capistrano has simplified my deployment workflow, but often times a pushed change will run into issues that I need to log into the server to troubleshoot via the console.

Is there a way to use capistrano or another remote administration tool to interact with the rails console on a server from your local terminal?

**Update:

cap shell seems promising, but it hangs when you try to start the console:

cap> cd /path/to/application/current
cap> pwd
 ** [out :: application.com] /path/to/application/current
cap> rails c production
 ** [out :: application.com] Loading production environment (Rails 3.0.0)
 ** [out :: application.com] Switch to inspect mode.

if you know a workaround for this, that'd be great

解决方案

I found pretty nice solution based on https://github.com/codesnik/rails-recipes/blob/master/lib/rails-recipes/console.rb

desc "Remote console" 
task :console, :roles => :app do
  env = stage || "production"
  server = find_servers(:roles => [:app]).first
  run_with_tty server, %W( ./script/rails console #{env} )
end

desc "Remote dbconsole" 
task :dbconsole, :roles => :app do
  env = stage || "production"
  server = find_servers(:roles => [:app]).first
  run_with_tty server, %W( ./script/rails dbconsole #{env} )
end

def run_with_tty(server, cmd)
  # looks like total pizdets
  command = []
  command += %W( ssh -t #{gateway} -l #{self[:gateway_user] || self[:user]} ) if     self[:gateway]
  command += %W( ssh -t )
  command += %W( -p #{server.port}) if server.port
  command += %W( -l #{user} #{server.host} )
  command += %W( cd #{current_path} )
  # have to escape this once if running via double ssh
  command += [self[:gateway] ? '\&\&' : '&&']
  command += Array(cmd)
  system *command
end
