Question

我在尝试将rails应用程序部署到朋友的服务器时遇到权限错误。我正在运行rails 3.1.3，ruby-1.9.2-p290，capistrano 2.11.2，Mac OS 10.6.8，我们设置了ssh密钥。但是，我们无法确定权限问题的来源。我们认为可能是capistrano试图将代码从git repo作为GIT用户推送到部署目录，或类似的东西。但这是我们的第一次部署尝试，所以我们不确定。任何帮助都将非常感激！

哦，这是我的朋友告诉我指定的更多细节： appsrv-04.example.ca是主机的规范FQDN，project.example.ca是指向appsrv-04.example.ca的A记录的CNAME。 git和deploy用户的known_hosts文件包含所有appsrv-04，appsrv-04.example.ca，project和project.example.ca。

以下是运行上限部署的输出：更新。

这是我的部署文件：

require "rvm/capistrano"          

set :application, "Project"

set :scm, "git"

Answer 1

你几乎肯定正确地诊断了这个问题;您正在尝试以部署用户身份检出github存储库，并且未正确设置转发的密钥。看起来你在Capistrano中打开了forward_agent ...你是否在你的代理中添加了你的密钥以便正确转发？

尝试使用ssh-add ~/.ssh/id-rsa并再次部署。

Answer 2

问题解决了。通过克隆现有虚拟主机并更改IP来创建虚拟主机。我更新了/ etc / hosts文件以使用新的主机名，但显然不是新的IP。因此，当部署用户尝试ssh作为git用户时...它失败了，因为它正在使用的IP上没有git用户。
