Nginx 连接到 Unicorn 时权限被拒绝

我在网上尝试了很多建议，但没有任何效果。我让 unicorn 和 nginx 致力于在 CentOS 6.5 服务器上部署 ruby​​ on Rails 应用程序。它以前有效，但现在当我尝试拉起该网站时，我收到了错误的网关错误。我正在使用的两个主要文件是 unicorn.rb 配置文件和 nginx 的 default.conf 文件。这些文件的位置是：/home/myuser/myApp/config/unicorn.rb 和 /etc/nginx/conf.d/default.conf。以下是它们包含的内容：

独角兽.rb

Set the working application directory
# working_directory "/path/to/your/app"
working_directory "/home/myuser/myApp"

# Unicorn PID file location
# pid "/path/to/pids/unicorn.pid"
pid "/home/myuser/myApp/pids/unicorn.pid"

# Path to logs
# stderr_path "/path/to/log/unicorn.log"
# stdout_path "/path/to/log/unicorn.log"
stderr_path "/home/myuser/myApp/log/unicorn.log"
stdout_path "/home/myuser/myApp/log/unicorn.log"

# Unicorn socket
# listen "/tmp/unicorn.[app name].sock"
listen "/home/myuser/myApp/tmp/unicorn.myApp.sock"

# Number of processes
# worker_processes 4
worker_processes 2

# Time-out
timeout 30

默认配置文件

upstream app {
        # Path to Unicorn SOCK file, as defined previously
        server unix:/home/myuser/myApp/tmp/unicorn.myApp.sock fail_timeout=0;
}

server {


    listen 80;
    server_name localhost;

    # Application root, as defined previously
    root /root/myApp/public;

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

    location @app {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app;
    }

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;
}

我正在尝试从 myuser 运行这些东西，所以我不想移动 unicorn 文件或 myApp。为了设置这个我遵循https://www.digitalocean.com/community/articles/how-to-deploy-rails-apps-using-unicorn-and-nginx-on-centos-6-5但更改了某些步骤的目录。我知道当我不更改目录时该教程会起作用，但我确实需要它在我的用户主目录中运行。任何帮助表示赞赏。

看起来问题出在nginx上。当查看 nginx error.log 时，我得到以下信息：

我在网上找到的解决方案之一是禁用 SELinux。我尝试过，但没有帮助。这些文件的权限均为 777，因此不应发生这种情况。有任何想法吗？

我发现了问题。 unicorn.myapp.sock 的路径必须转到 root 上的 /tmp 目录，而不是 myuser 目录。另外，我的 nginx default.conf 文件中的根路径需要位于 root/myApp/public ，而不是我的根路径。我不知道最后一部分意味着什么，但它有效并且我很高兴。感谢所有帮助我到达这里的人。
