Nginx配置Https

1. Nginx配置Https和认证，仅供参考

           ssl on;
           #配置证书的路径
           ssl_certificate      /usr/local/nginx/conf/ssl/server.pem;
           ssl_certificate_key  /usr/local/nginx/conf/ssl/privkey.pem;

           #设置代理地址
           location / {
                proxy_pass http://192.168.1.110:18281;
             #  root   html;
             #  index  index.html index.htm;
           }
           #配置H5资源路径
           location  /dist/  {
               root  html;
               index  index.html;
               autoindex on;
           }
       }
   }

2. root 、alias指令区别（alias是一个目录别名的定义，root则是最上层目录的定义。alias后面必须要用“/”结束，否则会找不到文件的，而root则可有可无）

   location /img/ {
       alias /var/www/image/;
   }

   若按照上述配置的话，则访问/img/目录里面的文件时，ningx会自动去/var/www/image/目录找文件

   location /img/ {
       root /var/www/image;
   }

   若按照这种配置的话，则访问/img/目录下的文件时，nginx会去/var/www/image/img/目录下找文件

4. Nginx作为代理需要访问Nginx所在的服务才可以发挥作用。就像黄牛买票，需要找到某个黄牛作为代理再买票。
