Vue 前后端分离部署 nginx 配置

1.vue.config.js

'use strict'
const path = require('path')
const defaultSettings = require('./src/settings.js')

function resolve(dir) {
  return path.join(__dirname, dir)
}

const name = defaultSettings.title// 标题

const port = process.env.port || process.env.npm_config_port || 800 // 端口

// vue.config.js 配置说明
//官方vue.config.js 参考文档 https://cli.vuejs.org/zh/config/#css-loaderoptions
// 这里只列一部分，具体配置参考文档
module.exports = {
  // 部署生产环境和开发环境下的URL。
  // 默认情况下，Vue CLI 会假设你的应用是被部署在一个域名的根路径上
  // 例如 https://www.ruoyi.vip/。如果应用被部署在一个子路径上，你就需要用这个选项指定这个子路径。例如，如果你的应用被部署在 https://www.ruoyi.vip/admin/，则设置 baseUrl 为 /admin/。
  publicPath: process.env.NODE_ENV === "production" ? "/" : "/",
  // 在npm run build 或 yarn build 时 ，生成文件的目录名称（要和baseUrl的生产环境路径一致）（默认dist）
  outputDir: 'dist',
  // 用于放置生成的静态资源 (js、css、img、fonts) 的；（项目打包之后，静态资源会放在这个文件夹下）
  assetsDir: 'static',
  // 是否开启eslint保存检测，有效值：ture | false | 'error'
  lintOnSave: process.env.NODE_ENV === 'development',
  // 如果你不需要生产环境的 source map，可以将其设置为 false 以加速生产环境构建。
  productionSourceMap: true,
  // webpack-dev-server 相关配置
  devServer: {
    host: '0.0.0.0',
    port: port,
    open: true,
    proxy: {
      // detail: https://cli.vuejs.org/config/#devserver-proxy
      [process.env.VUE_APP_BASE_API]: {
        target: `http://localhost:8090/bem_api`,
        changeOrigin: true,
        pathRewrite: {
          ['^' + process.env.VUE_APP_BASE_API]: ''
        }
      }
    },
    disableHostCheck: true
  },
  configureWebpack: {
    name: name,
    resolve: {
      alias: {
        '@': resolve('src')
      }
    }
  },
  chainWebpack(config) {
    config.plugins.delete('preload') // TODO: need test
    config.plugins.delete('prefetch') // TODO: need test

    // set svg-sprite-loader
    config.module
      .rule('svg')
      .exclude.add(resolve('src/assets/icons'))
      .end()
    config.module
      .rule('icons')
      .test(/\.svg$/)
      .include.add(resolve('src/assets/icons'))
      .end()
      .use('svg-sprite-loader')
      .loader('svg-sprite-loader')
      .options({
        symbolId: 'icon-[name]'
      })
      .end()

    config
      .when(process.env.NODE_ENV !== 'development',
        config => {
          config
            .plugin('ScriptExtHtmlWebpackPlugin')
            .after('html')
            .use('script-ext-html-webpack-plugin', [{
            // `runtime` must same as runtimeChunk name. default is `runtime`
              inline: /runtime\..*\.js$/
            }])
            .end()
          config
            .optimization.splitChunks({
              chunks: 'all',
              cacheGroups: {
                libs: {
                  name: 'chunk-libs',
                  test: /[\\/]node_modules[\\/]/,
                  priority: 10,
                  chunks: 'initial' // only package third parties that are initially dependent
                },
                elementUI: {
                  name: 'chunk-elementUI', // split elementUI into a single package
                  priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
                  test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
                },
                commons: {
                  name: 'chunk-commons',
                  test: resolve('src/components'), // can customize your rules
                  minChunks: 3, //  minimum common number
                  priority: 5,
                  reuseExistingChunk: true
                }
              }
            })
          config.optimization.runtimeChunk('single'),
          {
             from: path.resolve(__dirname, './public/robots.txt'), //防爬虫文件
             to: './', //到根目录下
          }
        }
      )
  }
}

2.后端项目配置

# 开发环境配置
server:
  # 服务器的HTTP端口，默认为8080
  port: 8090
  servlet:
    # 应用的访问路径
    context-path: /bem_api
  tomcat:
    # tomcat的URI编码
    uri-encoding: UTF-8
    # tomcat最大线程数，默认为200
    max-threads: 800
    # Tomcat启动初始化的线程数，默认值25
    min-spare-threads: 30

3. nginx.conf 配置文件

#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;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
	
	server {
		listen      800;
		server_name   localhost;
		
		#  配置访问根目录，跳转到首页，try_files 其他路径访问			  失败跳转到首页
		location / {
			root   D:/nh_four/nh_web/dist;
			index  index.html index.htm;
			try_files $uri $uri/ /index.html;
        }
		# Vue 项目VUE_APP_BASE_API = '/bem_api'，所以此处也要跟Vue 匹配
		location /bem_api {

			proxy_pass http://localhost:8090/bem_api;
					proxy_set_header Host $host;
			proxy_set_header X-Real_IP $remote_addr;
			proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
			proxy_set_header Cookie $http_cookie;
		}
		
		
		error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
	
	
	}

    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

小结：

1.Vue-cli3 里面：env 里VUE_APP_BASE_API = ‘/bem_api’
要跟 nginx 里 location /bem_api 完全对应
2. proxy_pass http://localhost:8090/bem_api 要跟后台服务器路径完全对应 context-path: /bem_api
3. root 对应前端实际物理地址
