Capistrano和GitHub Private Repo - 权限被拒绝（publickey） [英] Capistrano and GitHub Private Repo – Permission denied (publickey)

问题描述

我继承了一个Rails项目，托管在Linode上。

以前的开发人员使用BitBucket存储库以及Capistrano进行部署。

自从在GitHub上设置私有存储库后，我试图让Capistrano配方工作。我没有运气。我在配置过程中继续出现publickey错误。

以下是我采取的步骤 -

1. 更新了Linode服务器上的Git remote（origin）URL以指向我的新存储库
   
2. 更新了Capfile中的存储库引用，以引用我的新存储库

3. 在Capfile中将 ssh_options [：forward_agent] 设置为true
生成一个SSH密钥local（id_rsa.pub）并将其添加到我在GitHub中的用户帐户中

4. 执行 ssh-add 命令，以确保身份添加了auth代理


5. Ran ssh -T [e-mail] 确认ssh已在本地正确设置


6. 登录到我的Linode服务器并运行 ssh -T [e-mail] 以确保它也能正常工作

另外，为了防止forward_agent属性不起作用，我甚至尝试在Linode服务器上生成一个SSH密钥，并添加它到GitHub。



毕竟，当我运行 cap deploy 时，出现以下错误：

以下是我正在使用的配方 -

 需要bundler / capistrano
 
服务器---- SERVER IP ---- ：：web，：app，：db，primary：true 
 
 set：application，blog
 set：user，deployer
 set：deploy_to，/ var / www / blog

 set：branch，master
 
 default_run_options [：pty] = true

 end $ deploy：finalize_update，deploy：symlink_config之后的b 
 
 $ b desc确保本地git与远程同步。 
任务：check_revision，roles：：web do 
除非`git rev-parse HEAD` ==`git rev-parse origin / master` 
 putsWARNING：HEAD不一样origin / master
 puts运行`git push`来同步更改。 
退出
结束
结束
在deploy，deploy：check_revision之前
结束
  

我似乎无法弄清楚我要出错的地方 - 任何帮助都将不胜感激。

UPDATE





我还确保将以下内容添加到本地〜/ .ssh / config文件中...

 主机mydomain.com 
 ForwardAgent是
  




解决方案

今天我找到了MAC的根本原因。我的ssh密钥没有添加到身份验证代理，因此密钥未被转发。解决方案是执行以下命令：

blockquote
ssh-add〜/ .ssh / id_dsa
blockquote>



（或者如果您使用rsa键，则使用ssh-add〜/ .ssh / id_rsa）


I've inherited a Rails project, hosted on Linode.

The previous developer was using a BitBucket repository, along with Capistrano for deployments.

I've since setup a private repository on GitHub, and I'm trying to get the Capistrano recipe to work. I'm having no luck. I continue to get a publickey error during deployment.

Here are the steps I've taken –

1. Updated the Git remote (origin) URL on the Linode server to point to my new repository
2. Updated the repository reference in the Capfile, to reference my new repository
3. Ensured ssh_options[:forward_agent] was set to true in the Capfile
4. Generated an SSH key locally (id_rsa.pub) and added it to my user account in GitHub
5. Executed the ssh-add command, to ensure the identity was added for auth agent
6. Ran ssh -T [e-mail] to confirm ssh was properly setup locally
7. Logged into my Linode server and ran ssh -T [e-mail] to ensure it was working also

Additionally, just in case the forward_agent property wasn't working, I even tried generating an SSH key on the Linode server, and adding it to GitHub as well. No luck.

After all of this, when I run cap deploy, I get the following error:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly    

Below is the recipe I'm using –

require "bundler/capistrano"

server "----SERVER IP----", :web, :app, :db, primary: true

set :application, "blog"
set :user, "deployer"
set :deploy_to, "/var/www/blog"
set :deploy_via, :remote_cache
set :use_sudo, false

set :scm, "git"
set :repository, "[e-mail]:--MY USERNAME--/blog.git"
set :branch, "master"

default_run_options[:pty] = true
ssh_options[:forward_agent] = true

after "deploy", "deploy:cleanup" # keep only the last 5 releases

namespace :deploy do
  task :start do; end
  task :stop do; end
  task :restart, roles: :app, except: {no_release: true} do
    run "touch #{deploy_to}/current/tmp/restart.txt"
  end

  task :setup_config, roles: :app do
    sudo "ln -nfs #{current_path}/config/apache.conf /etc/apache2/sites-available/blog"
    run "mkdir -p #{shared_path}/config"
    put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml"
    puts "Now edit the config files in #{shared_path}."
  end
  after "deploy:setup", "deploy:setup_config"

  task :symlink_config, roles: :app do
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
    run "ln -nfs #{shared_path}/public/avatars #{release_path}/public/avatars"    
  end
  after "deploy:finalize_update", "deploy:symlink_config"

  desc "Make sure local git is in sync with remote."
  task :check_revision, roles: :web do
    unless `git rev-parse HEAD` == `git rev-parse origin/master`
      puts "WARNING: HEAD is not the same as origin/master"
      puts "Run `git push` to sync changes."
      exit
    end
  end
  before "deploy", "deploy:check_revision"
end

I can't seem to figure out where I'm going wrong – any help would be greatly appreciated.

UPDATE

I've also ensured the following was added to my local ~/.ssh/config file...

Host mydomain.com
  ForwardAgent yes

解决方案

Today I found the root cause on MAC. My ssh key was not added to the authentication agent so the key was not forwarded. The solution was to execute the following command:

ssh-add ~/.ssh/id_dsa

(or ssh-add ~/.ssh/id_rsa if you use rsa key)
