嘗試www到no-www時inginx失敗

Question

我正在部署一個帶有jar文件的網站。這是我設置的第一臺服務器，所以我在這裏做了些什麼，但有點失落。我在我的nginx.config中有：

server{ 
    listen   80; 
    server_name  www.mySite.com; 
    return   301 $scheme://mySite.com$request_uri; 
} 

server { 
    listen  80; 
    server_name mySite.com; 

     location/{ 
      proxy_pass http://localhost:3000 ; 
     } 

     ..... 

我根據文檔設置了CNAME。

我已經試過了很多資源，理順了這一點：

http://nginx.org/en/docs/http/converting_rewrite_rules.html

Nginx no-www to www and www to no-www

http://rtcamp.com/wordpress-nginx/tutorials/nginx/www-non-www-redirection/

而繼續得到同樣的錯誤：

$ systemctl status nginx.service 
nginx.service - A high performance web server and a reverse proxy server 
    Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled) 
    Active: failed (Result: exit-code) since Fri 2013-09-27 06:22:30 UTC; 11s ago

Answer 1

我找到了解決方案。原來，我並不需要添加第二個服務器：

server { 
    listen  80; 
    server_name mySite.com www.mySite.com; 

     location/{ 
      proxy_pass http://localhost:3000 ; 
     } 

我不知道，如果這個絕對正確的答案，但我也嘗試從nginx.com這個例子，但是沒有工作：

server { 
    listen  80; 
    server_name example.com www.example.com; 
    ... 
} 

server { 
    listen  80 default_server; 
    server_name _; 
    return  301 http://example.com$request_uri; 
}
