nginx配置

alias 和 root 的区别

一般情况下，在location /中配置root，在location /xxx中配置alias是一个好习惯。

假如服务器路径为 /home/imooc/files/img/face.png

• root路径完全匹配访问 

         location /imooc {
            root /home;
         }

用户访问的时候请求为 url:port/imooc/files/img/face.png 

• alias可以为你的路径做一个别名, 对用户透明

         location /hello {
            alias /home/imooc;
         }

用户访问的时候请求为 url:port/hello/files/img/face.png , 如此相当于为目录/home/imooc取了一个别名

         location /images {
            alias /usr/share/nginx/html/images;
         }

         location /demo {
            root /usr/share/nginx/html;
            try_files $uri $uri/ /index.html;
            index index.html index.htm;
         }

       #  与上面的配置实现效果相同 
       #  location /demo {
       #     alias /usr/share/nginx/html/demo;
       #     try_files $uri $uri/ /index.html;
       #     index index.html index.htm;
       #  }

 

 

反向代理proxy_pass URL末尾加与不加/(斜线)的区别

举例说明,假设前端访问http://192.168.217.129/prod-api/captchaImage

nginx配置如下,proxy_pass URL后面没有/

经过nginx转发后实际到后台的请求地址是http://192.168.217.129/prod-api/captchaImage

nginx配置如下,proxy_pass URL后面有/

经过nginx转发后实际到后台的请求地址是http://192.168.217.129/captchaImage

 

区别就是加/(斜线)后的url不带location的匹配参数
