nginx开启gzip和静态资源缓存、location;静态资源cdn

1.开启gzip:

主要配置gzip和gzip_types

#user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}

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

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip on;

    # Compression level (1-9).

    #5 is a perfect compromise between size and cpu usage, offering about

    #75% reduction for most ascii files (almost identical to level 9).

    gzip_comp_level    9;


    # Don't compress anything that's already small and unlikely to shrink much

    # if at all (the default is 20 bytes, which is bad as that usually leads to

    # larger files after gzipping).

    gzip_min_length    256;

    gzip_disable "msie6";

    gzip_buffers 32 4k;

    gzip_http_version 1.1;

    # https://www.mail-archive.com/search?l=nginx@nginx.org&q=subject:%22Gzip+issue+with+Safari%22&o=newest&f=1  for safira

    gzip_static on;


    # Compress data even for clients that are connecting to us via proxies,

    # identified by the "Via" header (required for CloudFront).

    gzip_proxied       any;


    # Tell proxies to cache both the gzipped and regular version of a resource

    # whenever the client's Accept-Encoding capabilities header varies;

    # Avoids the issue where a non-gzip capable client (which is extremely rare

    # today) would display gibberish if their proxy gave them the gzipped version.

    gzip_vary          on;


    # Compress all output labeled with one of the following MIME-types.

    gzip_types

        application/atom+xml

        # 这个application/x-javascript还是有区别的

        application/javascript

        application/json

        application/ld+json

        application/manifest+json

        application/rss+xml

        application/vnd.geo+json

        application/vnd.ms-fontobject

        application/x-font-ttf

        application/x-web-app-manifest+json

        application/xhtml+xml

        application/xml

        font/opentype

        image/bmp

        image/svg+xml

        image/x-icon

        text/cache-manifest

        text/css

        text/plain

        text/vcard

        text/vnd.rim.location.xloc

        text/vtt

        text/x-component

        application/octet-stream

        text/x-cross-domain-policy;

    # text/html is always compressed by HttpGzipModule

    # include /etc/nginx/conf.d/*.conf;
    server {
        listen       80;
        server_name  localhost;
        root  /usr/share/nginx/html;
        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root  /usr/share/nginx/html;
            index  index.html index.htm;
        }

        location ~ /static/ {
            add_header Cache-Control no-cache;
            # root /webroot/static/;
        }

        location ~ /(js/*|css/*|img/*|font/*) {
            expires 30d;
            add_header Cache-Control public;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
}
    

const CompressionWebpackPlugin = require("compression-webpack-plugin");
// 可加入需要的其他文件类型，比如json
// 图片不要压缩，体积会比原来还大
const productionGzipExtensions = ["js", "css"];

module.exports = {
  configureWebpack: config => {
    if (process.env.NODE_ENV === "production"){
      return {
        plugins: [
          new CompressionWebpackPlugin({
            // filename: '[path].gz[query]',
            algorithm: "gzip",
            test: new RegExp("\\.(" + productionGzipExtensions.join("|") + ")$"),
            threshold: 10240, //对超过10k的数据进行压缩
            minRatio: 0.6 // 压缩比例，值为0 ~ 1
          })
        ]
      };
    }
  }
};

如何判别是否使用的是打包好带.gz文件的

 

 

 

 

2.配置静态资源缓存

 

nginx.conf里面配置server的http添加location ~*  \.(gif|jpg|jpeg|png|css|js|ico)${

　　expires  30d;

}

或者： location ~ /(js/*|css/*|img/*|font/*) {

 

}

3.nginx的location配置

location [=|~|~*|^~] /uri/ { … }
=是精确匹配
~ 是匹配正则限定大小写
~* 是匹配正则不限定大小写
^~  以xxx开头
!~和!~*分别为区分大小写不匹配及不区分大小写不匹配 的正则
