Question

我第一次尝试在EC2上部署Rails应用程序，但这样做并不成功。我的应用在本地工作。当我执行cap production deploy时，它部署时没有任何错误，似乎数据库已迁移并显示在我的EC2服务器上，但是我无法访问该页面并收到超时错误。此外，当我尝试重新启动Nginx时，没有任何反应。我认为问题在于Puma。

当我检查puma.sock文件所在的路径时，该目录为空。我试图手动启动Puma，用

创建一个文件

bundle exec puma -e production -b unix:///home/deploy/byc/shared/tmp/sockets/puma.sock

并没有开始。我收到错误：

[28924] Puma starting in cluster mode...
[28924] * Version 3.11.3 (ruby 2.5.0-p0), codename: Love Song
[28924] * Min threads: 5, max threads: 5
[28924] * Environment: production
[28924] * Process workers: 2
[28924] * Preloading application
[28924] * Listening on unix:///home/deploy/byc/shared/tmp/sockets/puma.sock
bundler: failed to load command: puma (/Users/matt/.rbenv/versions/2.5.0/bin/puma)

毋庸置疑，当Capistrano打开并且我无法部署应用程序时，它也无效。

这是我第一次部署任何内容，过去两天我已经完成了几十个问题而且不知道该怎么做。如果有人能指出我正确的方向，我将永远感激。
