uwsgiの.sockファイルが生成されないのはなぜですか？

過去6時間の間、頭を強くぶつかったが、何も効果がないようです。

私はnginxとuwsgiを介してDjangoをホストしようとしています。私の理解と研究に基づいて、nginx.confとuwsgi.iniファイルを設定しました。

nginx.conf

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    server unix:/tmp/abc.sock; # for a file socket
}

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name localhost; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 2048M;   # adjust to taste

    # Django media
    location /media  {
        alias /<path_to>/media;  # your Django project's media files - amend as required
    }

    location /static {
        alias /<path_to>/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        include     /<path_to>/uwsgi_params; # the uwsgi_params file you installed
        uwsgi_param REMOTE_USER $remote_user;
        uwsgi_param DATE_GMT $date_gmt;
        uwsgi_param DATE_LOCAL $date_local;
        uwsgi_param AUTH_TYPE Basic;
        uwsgi_read_timeout 600s;
        uwsgi_pass  django;
    }
}

uwsgi.ini

[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = <path_to>/site
# Django's wsgi file
module          = pjgweb.wsgi:application
# the virtualenv (full path)
home            = /<path_to>/ENV

# process-related settings
# gid
gid             = www-data
# uid
uid             = www-data
# master
master          = true
# maximum number of worker processes
processes       = 6
# maximum number of threads for each worker process
threads         = 5
# the socket (use the full path to be safe
socket          = /tmp/abc.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = true
thread_lock     = true
python_thread   = true
# set the DJANGO MODULE SETTINGS
env             = DJANGO_SETTINGS_MODULE=pjintegweb.settings_production
# Log to
logto           = /<path_to>/uwsgi-app.log
# Statistics
stats           = :9191
stats-http      = true

• また、nginx.confとuwsgi.iniへのシンボリックリンクも作成しました。

• systemd の Emperor.uwsgi.service ファイルを設定しました。

    [Unit]
    Description=uWSGI Emperor service
    After=syslog.target
  
    [Service]
    ExecStart=/usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data
    Restart=always
    KillSignal=SIGQUIT
    Type=notify
    StandardError=syslog
    NotifyAccess=all
  
    [Install]
    WantedBy=multi-user.target
  

nginxログファイルを確認すると、次のようになります。

• 次のコマンドを実行するとエラーは表示されませんが、コマンドラインに戻りません。なぜそうなのか分からない

  uwsgi --ini uwsgi.ini [uWSGI] /path_to/uwsgi.iniからINI設定を取得する

それは永遠にそこにあります。インターネット上でたくさんの投稿を見ましたが、そのどれも私には役に立たないようです。助けてください。ありがとうございます。
