capistrano版本3升級困惑

Question

我正在努力將capistrano v2升級到v3 5天。我試圖從本地機器部署到ec2實例開發環境。我無法繼續前進。我的痕跡在這裏

$帽開發部署：檢查

     # Your restart mechanism here, for example:

配置/部署/ development.rb

set :stage, :development 


role :app, %w{ec2-user@70.22.320.14}

Capfile

require 'capistrano/setup' 
require 'capistrano/deploy' 
require 'capistrano/bundler' 
require 'capistrano/rails/assets' 
require 'capistrano/rails/migrations' 

Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r } 

我的問題：

1. 我的git的路徑不被接受

2. SSH密鑰問題

Git和SSH密鑰與Capistrano的工作2爲同樣的應用程序，我正在部署。升級到capistrano v3會帶來更大的頭疼。我可以連續做什麼。請指導我正確的步驟

Answer 1

我花了一些時間與capistrano3掙扎，這裏有一些提示，可能是他們可能是有用的：

1）官方手冊capistranorb.com。有關於你應該連續做什麼的提示。關於認證和授權的部分也很有幫助。有關於在工作站和服務器上配置ssh的一些提示。我遵循這個指南，它可以幫助我。嘗試從頭開始遵循本指南來構建您的deploy.rb。

也很有幫助指南：guide1，guide2

2）這是我的Capfile。注意rvm1/capistrano3和capistrano3 /獨角獸。非常有用的寶石。

require 'capistrano/setup' 

    require 'capistrano/deploy' 
    require 'capistrano3/unicorn' 
    require 'rvm1/capistrano3' 
    require 'capistrano/rvm' 
    require 'capistrano/bundler' 
    require 'capistrano/rails/assets' 
    require 'capistrano/rails/migrations' 

3）你可以試試下面的命令：

ssh ubuntu@ec2....amazonaws.com -v 

或

ssh git@github.com -v # from your EC2 server 

瞭解，當您試圖連接到您的EC2服務器會發生什麼。可能與pem key有關的問題？創建.pub項並嘗試使用它。不要忘了將它添加到〜/ SSH/authorized_keys中

cat id_rsa_aws.pub | ssh ubuntu@....amazonaws.com "cat >> 
/home/ubuntu/.ssh/authorized_keys" 

配置您的ssh-agent和別忘了在你的〜/添加。.bash_profile中是這樣的：

eval $(ssh-agent) 
ssh-add ~/.ssh/id_rsa_deploy_github 
ssh-add ~/.ssh/id_rsa_digital_ocean 

如果您在使用SSH的問題，或許你應該看看這個ssh-guide

還可以看我的應用程序，在那裏我使用capistrano3。可能你可以找到適合你的東西：#project

P.在沒有安裝一些VPS git的，所以它是最好檢查：

deployer@ec2***.amazonaws.com$ which git 

如果沒有找到：

deployer@ec2***.amazonaws.com$ sudo apt-get install git
