前端配置（使用 vue-cli3.x)

webpack 官网 compression-webpack-plugin

1. 安装依赖

$ npm i compression-webpack-plugin --save-dev

2. 修改 vue.config.js 配置文件

const productionGzipExtensions = /\.(js|css|html|svg)$/i;
const CompressionWebpackPlugin = require('compression-webpack-plugin');

module.exports = {
    configureWebpack: config => {
        // https://cli.vuejs.org/zh/guide/webpack.html#%E7%AE%80%E5%8D%95%E7%9A%84%E9%85%8D%E7%BD%AE%E6%96%B9%E5%BC%8F
        if (process.env.NODE_ENV === 'production') {
            // 为生产环境修改配置...
            // config.output.filename = 'assets/js/[name].[contenthash:8].min.js';
            // config.output.chunkFilename
            //     = 'assets/js/[name].[contenthash:8].min.js';
            config.plugins = [
                ...config.plugins,
                new CompressionWebpackPlugin({
                    filename: '[path].gz[query]',
                    algorithm: 'gzip',
                    test: productionGzipExtensions,
                    threshold: 2048,
                    minRatio: 0.8
                })
            ];
        } else {
            // 为开发环境修改配置...
            config.devtool = 'cheap-module-eval-source-map';
        }
    }
};

nginx 开启 gzip 优化

1.把阿里云服务上的文件拷贝到本地

# 把阿里云服务上的文件拷贝到本地
scp -r root@123.56.21.102:/etc/nginx/nginx.conf ./

2.nginx.conf 默认配置

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;


    server {
        listen       80 default_server;
        server_name  localhost;

        location / {
            proxy_pass http://127.0.0.1:8090;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

3.添加 gzip 之后 nginx.conf

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;


    server {
        # 开启gzip
        gzip on;

        # 启用gzip压缩的最小文件，小于设置值的文件将不会压缩
        gzip_min_length 1k;

        # gzip 压缩级别，1-9，数字越大压缩的越好，也越占用CPU时间，后面会有详细说明
        gzip_comp_level 9;

        # 进行压缩的文件类型。javascript有多种形式。其中的值可以在 mime.types 文件中找到。
        gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png application/vnd.ms-fontobject font/ttf font/opentype font/x-woff image/svg+xml;

        # 是否在http header中添加Vary: Accept-Encoding，建议开启
        gzip_vary on;

        # 禁用IE 6 gzip
        gzip_disable "MSIE [1-6]\.";

        # 设置压缩所需要的缓冲区大小
        gzip_buffers 32 4k;

        # 设置gzip压缩针对的HTTP协议版本
        gzip_http_version 1.0;

        listen       80 default_server;
        server_name  localhost;

        location / {
            proxy_pass http://127.0.0.1:8090;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

4. 把修改后的文件重新上传到阿里云服务

win 电脑建议使用 git bash 进行以下命令的操作

# 1. 上传到阿里云服务默认目录，使用 cd ~ 可以切换到对应目录
scp -r ./nginx.conf root@123.56.21.102:./

# 2. 使用ssh登录阿里云服务器, 输入以下命令按照提示输入密码就行
ssh root@123.56.21.102

# 3. 切换到默认 ~目录
cd ~

# 4. nginx配置文件的默认路径，/etc/nginx/nginx.conf
# 备份nginx.conf文件
# 把默认配置文件拷贝出来 并重命名为nginx.conf.backup
cp /etc/nginx/nginx.conf ./nginx.conf.backup

# 5. 把nginx修改后的配置文件再拷贝回去
cp ./nginx.conf /etc/nginx/nginx.conf

# cp: overwrite '/etc/nginx/nginx.conf'? y

# 6.重启nginx
systemctl restart nginx
