使用capistrano部署期间的ssh问题

Question

尝试将rails应用程序部署到朋友的服务器时,我收到了权限错误.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.任何帮助将非常感谢!

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,而project.example.ca是指向appsrv-04.example的A记录的CNAME .CA.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:更新的输出.

require "rvm/capistrano"          

set :application, "Project"

Answer 1

你几乎肯定会正确地诊断出这个问题; 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它正确转发？

尝试ssh-add ~/.ssh/id-rsa再次使用和部署.

Answer 2

问题解决了。虚拟主机是通过克隆现有主机并更改 IP 创建的。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，当部署用户尝试以 git 用户身份进行 ssh 时...它失败了，因为它使用的 IP 上没有 git 用户。
