Question

我有两个问题。一个小而一个更大的问题。

为什么我必须输入密码10次我的运行上限：冷
在我尝试通过teachmetocode-tuorial设置capistrano之后有一些stackoverflow的帮助。我坐下来，有许多部署capistrano的教程，并编写了我自己的deploy.rb新版本我们的gem env输出看起来如此

RubyGems环境：
- RUBYGEMS版本：1.8.15
  - RUBY VERSION：1.9.3（2012-02-16 patchlevel 125）[x86_64-linux]
  - 安装目录：/home/user/.rvm/gems/ruby-1.9.3-p125@myapp
  - RUBY EXECUTABLE：/home/user/.rvm/rubies/ruby-1.9.3-p125/bin/ruby
  - 可执行目录：/home/user/.rvm/gems/ruby-1.9.3-p125@myapp/bin
  - RUBYGEMS PLATFORMS：
  - 红宝石
  - x86_64的Linux的
  - GEM路径：
    - /home/user/.rvm/gems/ruby-1.9.3-p125@myapp
    - /home/user/.rvm/gems/ruby-1.9.3-p125@global
  - GEM配置：

    - ：backtrace =＆gt;假

我们的deploy.rb就在这里

require "bundler/capistrano"
set :application, "myapp"
set :repository,  "#{application}@myserver:/home/git/repos/#{application}.git"
set :scm, :git
set :user, "#{application}"
set :use_sudo, false
set :deploy_to, "/home/#{application}/#{application}"
set :deploy_via, :remote_cache
set :keep_releases, 5

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

set :branch, "master"

ssh_options[:forward_agent] = false
default_run_options[:pty] = true

before "deploy:assets:precompile", "bundle:install"

load 'deploy/assets'

namespace :deploy do
 task :start do ; end
 task :stop do ; end
 task :restart, :roles => :app, :except => { :no_release => true } do
   run "touch #{File.join(current_path,'tmp','restart.txt')}"
 end
end

我们的开发设置我们使用Apache + Passagner和http://beginrescueend.com/rvm/install/的rvm安装。在服务器上，我们以相同的方式安装它。每个用户（应用程序，gemsets或realuser）都必须是rvm组的成员...我们使用modrails安装passagner ... http://www.modrails.com/documentation/Users%20guide%20Apache.html#_installing_via_the_gem

但是当我使用cap deploy:cold时，为什么会出现错误。 cap deploy:check说You appear to have all necessary dependencies installed 错误在这里

有人可以帮助我们获得工作的capistrano

Answer 1

通过上限检查您的Capistrano路径，然后回显$ PATH 。你可能会看到你的标准/ usr / local / bin和/ usr / bin，但这不是RVM有Bundler的地方

编辑您的Capistrano config / deploy.rb文件，并添加以下行：

# Add RVM's lib directory to the load path.
$:.unshift(File.expand_path('./lib', ENV['rvm_path']))

# Load RVM's capistrano plugin.    
require "rvm/capistrano"

set :rvm_ruby_string, '1.9.2'
set :rvm_type, :user  # Don't use system-wide RVM

Rails 3 -- Bundler/Capistrano Errors

Answer 2

问题1（多次输入密码）：

您可以使用

在本地计算机上生成公钥/私钥对

ssh-keygen -t rsa（输入所有）

这会在/home/LOCAL_USER/.ssh/目录中生成两个文件（id_rsa和 id_rsa.pub ）

然后在服务器中创建或编辑文件/home/user/.ssh/ authorized_keys 并添加id_rsa.pub的内容

使用此功能，您的本地计算机有权访问此服务器（使用用户进行日志记录）而无需输入密码。

Answer 3

您没有使用rvm-capistrano集成，此处描述了集成：

https://rvm.beginrescueend.com/integration/capistrano/

请注意，rvm-capistrano不再是RVM安装的一部分，它是单独的gem，您需要将其包含在Gemfile中，并且config/deploy.rb中的要求也不要忘记设置{{1} }}
