capistrano版本3升级困惑

Question

我正在努力将capistrano v2升级到v3 5天。我试图从本地机器部署到ec2实例开发环境。我无法继续前进。我的痕迹在这里

$帽开发部署：检查

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 } 

我的问题：

1. 我的git的路径不被接受

2. SSH密钥问题

Git和SSH密钥与Capistrano的工作2为同样的应用程序，我正在部署。升级到capistrano v3会带来更大的头疼。我可以连续做什么。请指导我正确的步骤

Answer 1

我花了一些时间与capistrano3挣扎，这里有一些提示，可能是他们可能是有用的：

1）官方手册capistranorb.com。有关于你应该连续做什么的提示。关于认证和授权的部分也很有帮助。有关于在工作站和服务器上配置ssh的一些提示。我遵循这个指南，它可以帮助我。尝试从头开始遵循本指南来构建您的deploy.rb。

也很有帮助指南：guide1，guide2

2）这是我的Capfile。注意rvm1/capistrano3和capistrano3 /独角兽。非常有用的宝石。

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）你可以试试下面的命令：

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

或

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

了解，当您试图连接到您的EC2服务器会发生什么。可能与pem key有关的问题？创建.pub项并尝试使用它。不要忘了将它添加到〜/ 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和别忘了在你的〜/添加。.bash_profile中是这样的：

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

如果您在使用SSH的问题，或许你应该看看这个ssh-guide

还可以看我的应用程序，在那里我使用capistrano3。可能你可以找到适合你的东西：#project

P.在没有安装一些VPS git的，所以它是最好检查：

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

如果没有找到：

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