无法使用 capistrano 从 bitbucket 部署到 aws

Question

我尝试使用本地计算机上的 Capistrano 将 Ruby on Rails 应用程序从 bitbucket 上的存储库自动部署到 AWS EC2 实例。我尝试了 ssh、密码、无密码、转发 ssh 密钥、使用唯一的 ssh 密钥而不转发。每次我面对这个 ssh 跟踪 set :ssh_options, { verbose: :debug } :debug

请建议尝试什么

这是 deploy.rb

`
lock '3.2.1'
set :application, 'myapp'
set :repo_url, 'git@bitbucket.org:user/application.git'
set :branch, 'staging'
set :ssh_options, {
  verbose: :debug
}
 set :deploy_to, 'myfolder'
 set :scm, :git
 set :pty, true
 set :keep_releases, 5
set :use_sudo, true
set :rails_env, 'develop'
set :deploy_via, :copy
set :stages, ["staging", "production"]
set :default_stage, 'staging'
namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
      # execute :touch, release_path.join('tmp/restart.txt')
    end
  end
  #after :publishing, :restart
  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end
after :finishing, 'deploy:cleanup'
end
`

这是 staging.rb

`
role :app, %w{deploy@example.com}
role :web, %w{deploy@example.com}
role :db,  %w{deploy@example.com}
set :deploy_to, "/myfolder"
 server 'ec2-my-ip.eu-west-1.compute.amazonaws.com',
   user: 'ec2-user',
   port: '22',
   roles: %w{web app db},
   :primary => true,
   ssh_options: {
    user: 'ec2-user', # overrides user setting above
     keys: %w(/home/local_machine_user/.ssh/aws_ssh_key_pair.pem),
     forward_agent: false,
     auth_methods: %w(publickey password),
     password: 'please use keys'
   }
`

Answer 1

我遇到了类似的问题。对我来说，我错过了更改 example.com 地址。所以你的 staging.rb 应该是这样的：

role :app, %w{deploy@ec2-my-ip.eu-west-1.compute.amazonaws.com} role :web, %w{deploy@ec2-my-ip.eu-west-1.compute.amazonaws.com} role :db, %w{deploy@ec2-my-ip.eu-west-1.compute.amazonaws.com} set :deploy_to, "/myfolder" server 'ec2-my-ip.eu-west-1.compute.amazonaws.com', user: 'ec2-user', port: '22', roles: %w{web app db}, :primary => true, ssh_options: { user: 'ec2-user', # overrides user setting above keys: %w(/home/local_machine_user/.ssh/aws_ssh_key_pair.pem), forward_agent: false, auth_methods: %w(publickey password), password: 'please use keys' }

这是网络问题：

Errno::ENETUNREACH: Network is unreachable - connect(2)

检查您的安全组并确保您允许实例连接到端口 22 上的外部源。（您也可以使用“ssh -Tv git@bitbucket.org”从该实例测试它。）
