Capistrano的权限被拒绝的错误：设置

Question

我试着去部署与Capistrano的nginx的一个简单的应用程序和麒麟

• /srv/paintings.git（发起并推动回购）

• /SRV /绘画（应安装应用程序的地方）

我deploy.rb看起来像

Typing Yes keeps me waiting forever with no status updates 

Answer 1

我当我告诉Capistrano连接到一个我以前从未连接过的ssh服务器时，有一次类似的错误。您是否尝试过使用ssh root@109.0.0.0.05连接服务器（使用同一用户，即root而不是git）？

它可能会再次问你是否要信任服务器。如果是这样的话，我的猜测是卡皮斯特拉诺对你的'是'输入没有反应。

另外，您以root身份连接到您的服务器。这意味着你不需要将use_sudo设置为true。

不使用default_environment["PATH"] = "--"或bash提供完整的路径以某种方式（通常/bin/bash）
