Я создаю приложение, используя стек Nginx, uWSGI, Django и Postgresql. Приложение использует сокет Unix между Nginx и uWSGI. Разрешение файла на сокете - 775. Но я все равно получаю эту ошибку разрешения:
[error] 6978#0: *6725 connect() to unix:/path/to/socket failed (111: Connection refused) while connecting to upstream, client: 54.250.253.225, server: example.com, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/path/to/socket:", host: "example.com"

Может кто-нибудь сказать мне, что вызывает эту проблему с разрешениями?
По сути, мой был проектом Django. После сброса пароля root я повторно активировал свою виртуальную среду и перезапустил Nginx и Gunicorn. Это решило мою ошибку.
Перезапуск Nginx: sudo service nginx restart
Перезапуск Gunicorn: gunicorn --reload <your-wsgi-folder-name>.wsgi bind 0.0.0.0:8000
Во-первых, упростите чтение конфигурации и забудьте о восходящей информации. Я уже давно работаю с uWSGI. У меня часто были проблемы с сокетами (особенно в проектах python), но с PHP и uWSGI я получаю с сокетами, на удивление хорошо.
Если вы ДЕЙСТВИТЕЛЬНО настаиваете на использовании uWSGI, вам понадобятся 2 вещи!
1. config.ini, где хранятся все параметры uWSGI, относящиеся к вашим проектам, и конфигурация nginx.
2-й файл nginx.conf, где запросы направляются обратно в uWSGI для дальнейшей обработки.
/ etc / hosts:
127.0.0.1 projekte.local
nginx.conf:
server {
listen 127.0.0.1:80;
server_name projekte.local;
include uwsgi_params;
location / {
uwsgi_pass 127.0.0.1:3030;
}
projekte.conf (наш ini-файл):
[uwsgi]
socket = 127.0.0.1:3030
uid = daemon
gid = daemon
venv = /storage/PyENV/projekteENV
project_dir = /storage/PyProjects/bprojekte/projekte
chdir = %(project_dir)
master = true
plugins = plugins/python/python
check-static = %(project_dir)
static-skip-ext = .py
static-skip-ext = .pyc
static-skip-ext = .inc
static-skip-ext = .tpl
pidfile2 = /var/run/uwsgi/projekte.pid
disable-logging = false
processes = 8
cheaper = 2
#daemonize2 = true
enable-threads = true
offload-threads = N
py-autoreload = 1
wsgi-file = /storage/PyProjects/bprojekte/projekte/wsgi.py
вы переходите в папку приложения uWSGI и запускаете uWSGI с помощью:
./uwsgi --ini /path/to/projekte.conf
запустить nginx:
/usr/local/nginx/sbin/nginx
и откройте URL-адрес (в этом случае: http: //projekte.local)
Вопрос: Почему вы продолжаете использовать uWSGI? Gunicorn для отдельной машины достаточно хороша и намного проще в использовании. переключение с Gunicorn на uWSGI выполняется за одну минуту (без изменения ни одной строчки кода).
uWSGI предназначен для масштабирования ... для автономной работы ... хммм, я не знаю.
лучший, укротитель
Я сам смог решить проблему. Перезагрузил сервер. Затем я перезапустил Nginx и uWSGI с
sudo service nginx restart
sudo service uwsgi restart
Nginx перезапустился без проблем. Однако uWSGI вернул эту ошибку:
/etc/init.d/uwsgi: line 73: /usr/share/uwsgi/init/do_command: No such file or directory
Пытался перейти в каталог. Однако его не существовало. Итак, я создал каталог init в каталоге uwsgi с помощью:
sudo mkdir init
затем я вошел в новый каталог:
cd init
В этом каталоге я создал файл, который uWSGI не смог найти: do_command.
sudo nano do_command
Открыв редактор файлов, я вставил этот файл, который нашел: https://raw.githubusercontent.com/jbq/uwsgi/master/debian/uwsgi-files/init/do_command:

# This construction is needed for supporting configuration file names with

#
# Predefined delimeters are resetted to null character (by changing IFS and
# setting -d option of 'read' command) and then:
# * 'find -print0' command is used for finding all available confnames
# * 'while ... read' loop is used for iterating over found confnames
#
# Also process substitution is used, so that variables changed inside 'while'
# loop will retain their values after exiting from loop.
#
# By default 'find' command use emacs-style regexps. Emacs-style regexp
# processor with given regexp doesn't matches to file names with newline
# character. Posix-style regexp processor is working good.
#
# With executing 'sed' over found paths, relative configuration file
# paths are extracted from full paths provided with 'find' output.
# Firstly, common directory path (UWSGI_CONFDIR) is stripped from 'find'
# output. Secondly, all directories (except the first) and file extensions
# are stripped from result of first substitution.
#
# For example: list of found paths
# '/etc/uwsgi/apps-enabled/site.ini\0/etc/uwsgi/apps-enabled/dir/site2.ini'
# is transformed by sed into 'apps-enabled/site\0apps-enabled/site2'.

Затем я перезапустил uWSGI:
sudo service uwsgi restart
Приложение Django запустилось нормально.
Похоже, что служба uWSGI прослушивает сокет Unix с другим абсолютным путем (из-за chdir()
вызов). Ты можешь использовать lsof | grep "/path/to/socket"
чтобы найти абсолютный путь к прослушиваемому сокету Unix. Я думаю это /path/to/chdir/path/to/socket
.
