Nginx, Express.js и узел на порту 80

Question

Я запустил приложение Express.js на порту 8000, и я хочу работать с localhost, а не с localhost: 8000 в моей среде dev.

Я на Mac OSX El Capitan и используя Nginx 1.8.0

Я получаю 502 Bad Gateway и ERR_CONNECTION_TIMED_OUT ошибку.

Остановить nginx через sudo pkill nginx и начать с sudo nginx. Я также использую pm2 и запускаю его через sudo pm2 start bin/www --watch, здесь проблем нет. Я могу получить доступ к моему приложению на localhost: 8000

Я установил nginx через доморощенный.

/и т.д./хосты

Answer 1

Попробуйте это для вашего sites_enabled/default.conf:

upstream backend { 
    server localhost:8000; 
} 

server{ 
    listen 80; 
    server_name 127.0.0.1 localhost; 
    location/{ 
    proxy_set_header Upgrade $http_upgrade; 
    proxy_set_header Connection "upgrade"; 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_set_header Host $host; 
    proxy_pass http://backend; 
    } 
} 

Answer 2

Upgrade является заголовком от HTTP v1.1, возможно, потребуется включить proxy_http_version 1.1; при его использовании.
