为什么没有为 uwsgi 生成 .sock 文件？

为什么没有为 uwsgi 生成 .sock 文件？

在过去的 6 个小时里，我已经撞了头了，但似乎没有什么对我有用。

我正在尝试通过 nginx 和 uwsgi 托管 Django。根据我的理解和研究，我配置了 nginx.conf 和 uwsgi.ini 文件。

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

  • 我还为 nginx.conf 和 uwsgi.ini 创建了符号链接。

  • 我确实为 systemd 配置了emperor.uwsgi.service 文件

      [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

当我检查 nginx 日志文件时，我看到下面的内容

  • 当我执行以下命令时，我没有看到任何错误，但它永远不会返回到命令行。不知道为什么

    uwsgi --ini uwsgi.ini [uWSGI] 从 /path_to/uwsgi.ini 获取 INI 配置

它永远留在那里。我在互联网上看到了很多帖子，但似乎没有一个对我有帮助。请帮忙。谢谢。
