NGINX + Gunicorn + Flask Почему 500 Внутренняя ошибка сервера при отправке пост-запроса?

/ 04 марта 2019

Я использую Flask с NGINX и Gunicorn.Ubuntu 18.04.02.

Когда я запускаю сервер Flask по умолчанию, все работает.

Вперед.После подключения Gunicorn не работают пост-запросы.Но когда я запускаю Gunicorn с 3 рабочими gunicorn --bind 0.0.0.0:5000 wsgi:app -w 3, все работает.Окей!

Давай.Подключите NGINX.Мои конфиги:

/etc/nginx/nginx.conf

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 768;
}

http {
        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        include /etc/nginx/mime.types;
        default_type application/octet-stream;

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

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

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

/etc/nginx/sites-available/myproject

server {
    listen 80;
    server_name 157.230.103.16 www.157.230.103.16;

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

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/root/blend/myproject.sock;
    }
}

/etc/systemd/system/myproject.service
