Nginx 陷阱和常见错误（以下为正确或者推荐配置）

---

• 把 root 放在 location 区块外

      server {
          server_name www.example.com;
          root /var/www/Nginx -default/;
          location / {
              # [...]
          }
          location /foo {
              # [...]
          }
          location /bar {
              # [...]
          }
      }
  

• 简单的使用“ index ”指令一次就够了。只需要把它放到 http {} 区块里面，下面的就会继承这个配置

      http {
          index index.php index.htm index.html;
          server {
              server_name www.example.com;
              location / {
                  # [...]
              }
          }
          server {
              server_name example.com;
              location / {
                  # [...]
              }
              location /foo {
                  # [...]
              }
          }
      }
  

• 不要使用 if 判断 Server Name

  不推荐

   server {
         server_name example.com *.example.com;
             if ($host ~* ^www\.(.+)) {
                 set $raw_domain $1;
                 rewrite ^/(.*)$ $raw_domain/$1 permanent;
             }
             # [...]
         }
     }
  

  推荐配置

   server {
         server_name www.example.com;
         return 301 $scheme://example.com$request_uri;
   }
   server {
         server_name example.com;
         # [...]
   }
  

• 使用主机名来解析地址

  不推荐配置

  upstream {
      server http://someserver;
  }
  
  server {
      listen myhostname:80;
      # [...]
  }
  

  推荐配置

  upstream {
      server http://10.48.41.12;
  }
  
  server {
      listen 127.0.0.16:80;
      # [...]
  }
