Rails Capistrano身份驗證失敗錯誤

Question

我試圖部署我的Rails 4應用程序使用Capistrano 3.4，但不斷得到身份驗證失敗的錯誤。我只是不明白我應該在哪裏設置Git倉庫的密碼。

這裏運行命令cap production deploy --trace當是我的錯誤信息：

deploy.rb

lock '3.4.0' 

set :application, 'xxx' 
set :repo_url, 'https://xxx@bitbucket.org/xxx/myapp.git' 
set :deploy_to, 'home/xxx/Sites/myapp' 
set :scm, :git 
set :format, :pretty 
set :pty, true 

deploy/production.rb

server '123.45.678.90', user: 'xxx', roles: %w{web app} 
role :app, %w{xxx@123.45.678.90} 
role :web, %w{xxx@123.45.678.90} 
role :db, %w{xxx@123.45.678.90} 

現在我試圖反覆折騰中production.rb參數，但是我不斷收到語法錯誤。

# Custom SSH Options 
# ================== 
# You may pass any option but keep in mind that net/ssh understands a 
# limited set of options, consult the Net::SSH documentation. 
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start 
# 
# Global options 
# -------------- 
# set :ssh_options, { 
# keys: %w(/home/rlisowski/.ssh/id_rsa), 
# forward_agent: false, 
# auth_methods: %w(password) 
# } 
# 
# The server-based syntax can be used to override options: 
# ------------------------------------ 
# server '123.45.678.90', 
# user: 'defined_user', 
# roles: %w{web app}, 
# password: 'mypassword' 
# ssh_options: { 
#  user: 'user', 
#  keys: %w(/home/user_name/.ssh/id_rsa), 
#  forward_agent: false, 
#  auth_methods: %w(publickey password) 
# } 

Answer 1

您應該在您的服務器上生成一個SSH密鑰對。然後，將公鑰作爲部署添加到你的git倉庫中。之後，您應該可以在不輸入密碼的情況下下載您的git repo

Answer 2

部署密鑰通常用於自動部署，當您絕對必須將密鑰留在服務器上時，並且萬一它被攻破 - 某人也可以訪問您的回購。

驗證服務器訪問git的其他方法是使用ssh代理轉發，這種方式在這方面有點安全。

運行ssh-add您當前SSH密鑰添加到代理會話，然後再試一次，也Capistrano的應啓用SSH代理轉發，在3它是默認啓用的，但以防萬一：

set :ssh_options, { forward_agent: true }
