使用 wsgi 运行 nginx 时找不到页面

我想使用 nginx 运行一个 flask 应用程序。我经历了本教程直到我从命令行使用 wsgi 启动服务时，一切都正常（这意味着我可以访问我的页面localhost:8000并显示Hello, there!消息）。我的项目位置如下：

(venv-dvwa) root@kali:~/services/dvwa# pwd
/root/services/dvwa
(venv-dvwa) root@kali:~/services/dvwa# ls
dvwa.sock  main.py  __pycache__  requirements.txt  uwsgi.ini  venv-dvwa  wsgi.py
(venv-dvwa) root@kali:~/services/dvwa# which uwsgi
/root/services/dvwa/venv-dvwa/bin/uwsgi
(venv-dvwa) root@kali:~/services/dvwa#

nginx 的配置文件：

(venv-dvwa) root@kali:~/services/dvwa# cat /etc/nginx/nginx.conf 
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
    server {
        listen 80;
        server_name server_domain_or_IP;
        location / {
            include uwsgi_params;
            uwsgi_pass unix:/root/services/dvwa/dvwa.sock;
        }
    }
}

并为我服务：

(venv-dvwa) root@kali:~/services/dvwa# cat /etc/systemd/system/dvwa.service 
[Unit]
Description=uWSGI instance to serve dvwa csp hacks
After=network.target

[Service]
User=root
Group=root
WorkingDirectory=/root/services/dvwa
Environment="PATH=/root/services/dvwa/venv-dvwa/bin"
ExecStart=/root/services/dvwa/venv-dvwa/bin/uwsgi --ini uwsgi.ini

[Install]
WantedBy=multi-user.target

两项服务均已启动并正在运行：

当我localhost在浏览器中输入或输入我的 IP 地址时，我收到 404 nginx 消息。我正在运行最新的 kali linux 版本（那是因为我想尝试另一个项目 - dvwa 并学习一些东西）。最后一条通知：我知道在生产目的中使用 root 帐户是个坏主意，但这个项目不打算这样做。

答案1

好的，我的设置有几个问题。首先，包括默认启用的站点覆盖了我的设置。其次，我更改了服务器名称以匹配所有情况。最后但并非最不重要的是，必须为套接字赋予 666 而不是 660 权限。

我的新 nginx.conf：

root@kali:~/services/dvwa# cat /etc/nginx/nginx.conf
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    # include /etc/nginx/sites-enabled/*;
    server {
        listen 80;
        server_name _;
        location / {
            include uwsgi_params;
            uwsgi_pass unix:/root/services/dvwa/dvwa.sock;
        }
    }
}

和 uwsgi.ini：

root@kali:~/services/dvwa# cat uwsgi.ini 
[uwsgi]

module = wsgi

master = true
processes = 1

socket = dvwa.sock
chmod-socket = 666
vacuum = true

die-on-term = true

编辑我认为我的解决方案有点过度，所以如果有人能建议更有效的方法，我会很乐意将其包含在我的答案中。
