我有一個作爲Web服務器由Nginx控制的Web應用程序。當它被配置如下，它的工作。打到http://192.168.33.10:9174/產生「需要402付款」Nginx可以作爲反向代理，但不會通過套接字將流量傳遞給Puma
# /etc/nginx/sites-enabled/myapp
server {
listen 9174;
server_name 127.0.0.1;
location /status {
stub_status on;
access_log off;
}
return 402;
}
它的工作原理。
然後我試圖讓它將流量轉發到Puma應用服務器，但失敗了。然後我設置了一堆代理如下：
# /etc/nginx/sites-enabled/myapp
upstream sqlitething {
server www.sqlite.org;
}
upstream hwacithing {
server www.hwaci.com;
}
upstream appthing {
#server unix:///home/deployer/myapp/shared/sockets/socktest.sock
server unix:/home/deployer/myapp/shared/sockets/puma.sock fail_timeout=0;
}
server {
listen 80;
server_name 192.168.33.10;
location/{
proxy_pass http://sqlitething;
}
}
server {
listen 8080;
server_name 192.168.33.10;
location/{
proxy_pass http://hwacithing;
}
}
server {
listen 8099;
server_name 192.168.33.10;
location/{
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://appthing;
}
}
server {
listen 9175;
server_name 192.168.33.10;
return 402;
}
這裏是我的結果時，我打了瀏覽器的網址：
- http://192.168.33.10:80，它代理www.sqlite.org（預期） 。
- http://192.168.33.10:8080，它代理www.hwaci.com（預期）
- http://192.168.33.10:9175，返回HTTP 402（需要付款）消息（預期）
- http://192.168.33.10:8099想我重定向到https://appthing，但沒有發生（NOT預期）
套接字文件存在與權限如下：
srwxrwxrwx 1 deployer deployer 0 Jun 8 19:15 /home/deployer/myapp/shared/sockets/puma.sock
-------- UPDATE 6月8日5： 57 EST --------------------
我嘗試了失敗的網址如下：
$ curl -isL http://192.168.33.10:8099

我試成功URL以下

----- UPDATE 6月9日上午11時24分EST --------------
我在線加入
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_redirect off;
到連接到Unix套接字的端口8099的服務器/監聽塊。我得到了同樣的結果。
我後來去http://blog.honeybadger.io/how-unicorn-talks-to-nginx-an-introduction-to-unix-sockets-in-ruby/當他們指定成立了一個小插座服務器，但與
unix:///home/deployer/myapp/shared/sockets/socktest.sock
插座然後我修改了nginx.conf所以它不會守護進程和錯誤會去到標準輸出。
daemon off;
error_log /dev/stdout info;
然後我nginx的跑了作爲
> sudo nginx -c nginx.conf
當我跑到捲曲擊中的nginx /插座組合，我得到這個：
$ curl -isL http://192.168.33.10:8099
HTTP/1.1 502 Bad Gateway

nginx的日誌是這樣的：

我配置所述上游彪馬作爲各種配置指南指定。我究竟做錯了什麼？
有沒有辦法查看Puma進程是否真正在爲我的Web應用程序提供服務？
有沒有辦法使用curl或wget和通過Unix套接字來訪問Puma進程（unix：/home/deployer/myapp/shared/sockets/puma.sock）？
你是什麼意思的「試圖重定向，但沒有發生」？當你點擊'http：//192.168.33.10：8099 /'url時，究竟發生了什麼？ – Roman
網絡瀏覽器將我重定向到https：// appthing。 –
你的意思是說，'https：// appthing /'字面意思？ – Roman
