Question

我一直在将我的网络应用部署到aws。我正准备连接到网站，我超时了。所以我进入EC2，看看为什么它给了我一个时间。我收到了这个错误：

/opt/rubies/ruby-2.3.1/lib/ruby/gems/2.3.0/gems/rack-2.0.1/lib/rack/server.rb:374:in `delete': Operation not permitted @ unlink_internal - /var/app/current/tmp/pids/server.pid (Errno::EPERM)

from bin/rails:9:in `require'
from bin/rails:9:in `<main>'

可能导致它的原因以及如何解决它。

先谢谢，康纳

查看rack-2.0.1/lib/rack/server.rb的第374行，似乎正在尝试（并且失败）删除/var/app/current/tmp/pids/server.pid处过期的pid文件。我怀疑这是一个权限问题 - 也就是说，无论用户拥有/var/app/current目录的是什么，都与您尝试运行rails server的用户不同。您可以sudo rm /var/app/current/tmp/pids/server.pid删除pid，然后重试。

操作不允许Rails AWS
