我试图部署我的Rails 4应用程序使用Capistrano 3.4，但不断得到身份验证失败的错误。我只是不明白我应该在哪里设置Git仓库的密码。Rails Capistrano身份验证失败错误
这里运行命令cap production deploy --trace当是我的错误信息：

现在我试图反复折腾中production.rb参数，但是我不断收到语法错误。
# 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)
# }

您应该在您的服务器上生成一个SSH密钥对。然后，将公钥作为部署添加到你的git仓库中。之后，您应该可以在不输入密码的情况下下载您的git repo
答
部署密钥通常用于自动部署，当您绝对必须将密钥留在服务器上时，并且万一它被攻破 - 某人也可以访问您的回购。
验证服务器访问git的其他方法是使用ssh代理转发，这种方式在这方面有点安全。
运行ssh-add您当前SSH密钥添加到代理会话，然后再试一次，也Capistrano的应启用SSH代理转发，在3它是默认启用的，但以防万一：
set :ssh_options, { forward_agent: true }

访问本教程，我知道它是用于webfaction托管，但它也适用于其他服务器以及https://docs.webfaction.com/software/rails.html#deploying-a-ruby-on-rails-application- with-capistrano – mariowise
@ joshua.paling这是解决方案。谢谢。如果你希望你可以发表你的评论作为答案，所以我可以标记为正确的。 – aishaq11
