Php WP Deploy，Capistrano，bundle exec cap生产上传问题：pull

我正在尝试获取服务器上的uploads目录，我将其用作部署系统

所有其他SSH命令都可以工作，比如deploy等，但是这个命令由于某种原因失败，下面是跟踪

Tasks: TOP => uploads:pull

Production.rb

ec2密钥是有效的，它适用于以下内容：

bundle exec cap production deploy

但由于某种原因，当我试图从生产环境中获取uploads目录时，它不起作用

---

uploads dir确实存在于，/var/www/html/shared/content/uploads，并且它非常流行。

首先，我假设您知道以root用户身份运行此类命令是一种不好的做法，并且您有很好的理由这样做

ssh密钥不知怎么搞砸了。该行：

rsync stderr: Permission denied (publickey).

他指出了这一点

我不确定它为什么要在本地主机上以root用户身份运行rsync命令。可能是没有为根用户安装ssh密钥

试着跑步

rsync -avzO ec2-user@project.com:/var/www/html/shared/content/uploads/ content/uploads

看看它是否能发光

rsync stderr: Permission denied (publickey).

rsync -avzO ec2-user@project.com:/var/www/html/shared/content/uploads/ content/uploads
