Amazon AWS，cap deploy:检查失败

Question

我正在尝试使用capistrano设置到AWS EC2实例的部署。为了测试，我使用

cap testing deploy:check

但Capistrano失败了，原因是：

    triggering load callbacks
  * 2013-03-12 15:41:27 executing `testing'
    triggering start callbacks for `deploy:check'
  * 2013-03-12 15:41:27 executing `multistage:ensure'
  * 2013-03-12 15:41:27 executing `deploy:check'
  * executing "test -d /......./releases"
    servers: ["ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com"]
    connection failed for: ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com
    (NoMethodError: undefined method `each' for "publickey":String)

我使用.pem文件进行连接，deploy.rb脚本如下所示：

set :stages, %w(production testing)
set :default_stage, 'testing'
require 'capistrano/ext/multistage'

set :application, 'app_name'
set :user, 'the_user'
set :group, 'the_group'

set :scm, :git
set :repository,  "git@github.com:......./#{application}.git"
set :deploy_to, '/......./'
set :deploy_via, :remote_cache

# Authentication setup
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
ssh_options[:auth_methods] = 'publickey'
ssh_options[:keys] = ['~/........pem']

你知道为什么会发生这种事吗？

Answer 1

尝试将您的公钥放在服务器上。

并删除

ssh_options:auth_methods =‘公钥’

ssh_options:keys =‘~/.......pem’

它应该是可行的

Answer 2

我最近升级了一个开发服务器，看到了同样的行为。错误消息看起来像是Capistrano需要一个迭代器，而publicKey的赋值并没有这样定义它。

尽管这听起来很微不足道，但试着改变：

ssh_options[:auth_methods] = 'publickey'
ssh_options[:keys] = ['~/........pem']

至：

set :ssh_options, {:auth_methods => "publickey"}
set :ssh_options, {:keys => ["~/......pem"]}

您可能需要对身份验证设置中的其他项目执行相同的操作。祝好运。

Answer 3

删除行

ssh_options[:auth_methods] = 'publickey'
