Ruby on rails 轨道4+；Capistrano 3:致命：部署时无法从远程存储库读取

在使用Capistrano3部署Rails4应用程序时，我遇到以下错误

这是capistrano配置

config/deploy.rb

# config valid only for current version of Capistrano
lock '3.4.0'

set :application, 'magnificent'
set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'
set :deploy_to, '/home/deploy/magnificent'

set :linked_files, %w{config/database.yml config/secrets.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
set :branch, 'develop' #set/ :branch,`git rev-parse --abbrev-ref HEAD`.chomp
set :ssh_options, { forward_agent: true }

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :publishing, 'deploy:restart'
  after :finishing, 'deploy:cleanup'
end

namespace :deploy do

  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

end

set :stage, :production
server 'xx.xx.xx.xx', user: 'deploy', roles: %w{web app}

production.rb

# config valid only for current version of Capistrano
lock '3.4.0'

set :application, 'magnificent'
set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'
set :deploy_to, '/home/deploy/magnificent'

set :linked_files, %w{config/database.yml config/secrets.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
set :branch, 'develop' #set/ :branch,`git rev-parse --abbrev-ref HEAD`.chomp
set :ssh_options, { forward_agent: true }

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :publishing, 'deploy:restart'
  after :finishing, 'deploy:cleanup'
end

namespace :deploy do

  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

end

set :stage, :production
server 'xx.xx.xx.xx', user: 'deploy', roles: %w{web app}

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
set :rvm_type, :user
set :rvm_ruby_version, '2.2.2'

我还将远程服务器的/home/deploy/.ssh/id_rsa.pub复制到github部署密钥

更新 我确认我能够访问远程repo，也能够访问GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/globalize/GIT-SSH.sh/usr/bin/env GIT ls remote--headsgit@github.com：BoTreeConsultingTeam/globalize.git命令在远程服务器上工作。

当前解决方案 最近我使用了不同的解决方案。在

cap production deploy

之前，我运行以下命令

eval“$（ssh代理-s）”

ssh add~/.ssh/id\u rsa

先前的解决方案 我可以通过替换

set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'

与

注意如果密码包含特殊字符，则应使用url编码。您可以在irb中使用

URI:：encode

快速编码

对于使用Capistrano 2的其他部署，我永远不需要提供github凭据

有人能告诉我为什么必须在

repo\u url

中指定git用户名/密码吗

---

在中还有一个解决方案同样有效。

我也有类似的问题（ubuntu）。ssh代理应该处于启用状态。您可以将其添加到启动应用程序中。

我也有这个问题。原来我加载了错误的SSH密钥，它干扰了部署。通过删除错误加载的ssh密钥解决了此问题，如下所示：

ssh add-d~/.ssh/错误的ssh密钥

然后再次运行Capistrano部署。

如果您是第一次部署到服务器，并且git服务器不在部署服务器的已知主机列表中，也可能发生这种情况

因此，登录到远程服务器，然后对存储库执行git请求，将导致git服务器添加到已知主机列表中

像这样：

git ls-remote git@bitbucket.org:your_gitbucket_user_id/your_repo.git master

The authenticity of host 'bitbucket.org (104.192.143.2)' can't be established.
RSA key fingerprint is SHA256:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojabwzha.
Are you sure you want to continue connecting (yes/no)? yes

您应该确认连接

Warning: Permanently added 'bitbucket.org,104.192.143.2' (RSA) to the list of known hosts.

现在尝试使用capistrano任务进行部署

cap production deploy

---

转到服务器框get id_rsa.pub并将其添加到github上的密钥中一个常见错误是，您可能需要将服务器的公钥添加到repo的访问密钥列表中。我总是忘记这一点，并添加本地环境中从未工作过的公钥。

是的，这也是有效的。最近，在部署之前，我开始使用

ssh代理。更新了我的答案。我本来不会实现原来的解决方案，但你的更新确实帮助我解决了问题。它是有效的，但这很糟糕，将其提交到git中的安全性真的很差
