nginx错误：（13：权限被拒绝）连接到上游时）

Question

2016/02/03 11:58:07 [info] 19754#0: *73 client closed connection while waiting for request, client: ###.##.##.###, server: 0.0.0.0:443

2016/02/03 11:58:07 [crit] 19754#0: *74 connect() to unix:///home/my-user-name/apps/my-web-app/shared/tmp/sockets/my-web-app-puma.sock failed (13: Permission denied) while connecting to upstream, client: ###.##.##.###, server: , 
request: "GET / HTTP/1.1", upstream: "http://unix:///home/my-user-name/apps/my-web-app/shared/tmp/sockets/my-web-app-puma.sock:/", host: "###.###.###.###"

注意：最后一个###.##.###.####是运行代码的google compute VM的外部IP。我相信前两个IP是我的家IP。

在连接到上游:[nginx]时，我尝试了:setsebool httpd_can_network_connect上的httpd_can_network_connect:(13:权限被拒绝），并返回:setsebool:SELinux被禁用。但是问题仍然存在。

在连接到上游:[nginx]时，我也查看了（13：权限被拒绝），但它似乎是UWSGI所特有的

upstream puma {
  server unix:///home/my-user-name/apps/my-web-app/shared/tmp/sockets/my-web-app-puma.sock;

  try_files $uri/index.html $uri @puma;

    proxy_set_header Host $http_host;

  }
  error_page 500 502 503 504 /500.html;
  client_max_body_size 10M;
  keepalive_timeout 10;
}

我用sudo服务nginx restart运行nginx，然后用:rack_env=production bundle exec puma-p 3000运行puma，它返回：

Puma starting in single mode...
* Version 2.14.0 (ruby 2.1.7-p400), codename: Fuchsia Friday
* Min threads: 0, max threads: 16
* Environment: production
* Listening on tcp://0.0.0.0:3000
Use Ctrl-C to stop

有人建议我在unix上运行puma，而不是在TCP3000上运行，这样它就可以与nginx相匹配

我尝试通过以下命令在unix上运行puma：

RACK_ENV=production bundle exec puma -d -b unix:///tmp/my-web-app.sock --pidfile /tmp/puma.pid

它给出了：

Puma starting in single mode...
* Version 2.14.0 (ruby 2.1.7-p400), codename: Fuchsia Friday
* Min threads: 0, max threads: 16
* Environment: production
* Daemonizing...

它读取上面的文本，但它不会逗留，命令提示符立即再次出现，尽管'...'在最后。

这个命令似乎不起作用，所以如果有人可以建议如何在unix上运行puma，而不是在TCP3000上运行，那么我可以完成这个建议。（尽管我怀疑在与彪马有关的任何事情之前，可能会出现配置nginx的问题）

这意味着这种方法是不正确的，因为如果没有nginx，当我访问外部IP时，它现在不会返回任何东西服务器拒绝连接。与原来的相反：

We're sorry, but something went wrong.

If you are the application owner check the logs for more information.

如果有人知道如何防止最初的错误，任何建议都将非常感谢。

编辑5原来的问题仍然存在，但是有人能告诉我这是https问题还是ssl问题吗？

我相信这是因为端口80比其他端口具有更高的权限造成的。因此，我运行了sudo rack_env=production bundle exec puma-p80，但它刚刚返回:您的Ruby版本是1.9.3，但您的Gemfile指定了2.1.7

我和你有同样的错误，我有一个解决方案，但不知道它应该是正确的。更改文件/etc/nginx/nginx.conf的第一行

用户www-data；
到
用户根；

然后使用以下命令重新启动nginx：
