场景

项目需要区分系统使用者身份，存在诸如xxx/admin 、 xxx/client这样的访问地址。 因此在需要进行对相应项目进行独立部署

部署环境

  os： mac（10.12.6）
  服务器： Nginx (1.17.1)
  前端项目开发框架： Umi (2.8.11)

解决方案一：（nginx指定静态资源路径）

项目配置

Umi中config配置(config/config.js)添加如下参数

base: '/admin'   (如果为client端，相应为base: '/client');

参考;https://umijs.org/zh/guide/deploy.html#%E9%83%A8%E7%BD%B2-html-%E5%88%B0%E9%9D%9E%E6%A0%B9%E7%9B%AE%E5%BD%95
原理请查阅react-router的basename

Nginx配置

Nginx (www)文件结构如下

    ├── 50x.html
    ├──admin
    │ ├──index.html
    │ ├──latout.css
    │ ├──main.js
    ├──client
    │ ├──index.html
    │ ├──latout.css
    │ ├──main.js

Nginx配置如下

  
#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

    worker_connections  1024;

        location = /50x.html {

        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

    }

    include servers/*;
}

解决方案二（webpack配置publicPath）

1、 项目配置

base: '/admin/',
publicPath: '/admin/',

2、移除Nginx中静态资源配置项： location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|css|js|eot|svg|ttf|woff|woff2|properties|json)$ {...}

解释：

base做为路由路径，为匹配nginx的 location ^~ /admin{ }
publicPath为静态资源指定路径，打包出来css与js引入路径如图所示：

css.jpg

js.jpg

su.
