操作环境

  • 硬件：华为云服务器
  • 操作系统：Rocky Linux 9.0 64bit
  • 服务器软件：nginx 1.24.0，php 8.2.6，openssl 3.0.7，WordPress6.2.2

基本假设

1.nginx已开启https服务
2.nginx已配置http转发https
3.nginx已配置gzip模块

操作方法

1.修改nginx.conf文件，修改 HTTPS 部分内容。

在 HTTPS的server块添加以下内容，并保存修改：

# BEGIN Browser Cache
    gzip on;
    gzip_types text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/richtext text/plain text/xsd text/xsl text/xml image/bmp application/java application/msword application/vnd.ms-fontobject application/x-msdownload image/x-icon application/json application/vnd.ms-access video/webm application/vnd.ms-project application/x-font-otf application/vnd.ms-opentype application/vnd.oasis.opendocument.database application/vnd.oasis.opendocument.chart application/vnd.oasis.opendocument.formula application/vnd.oasis.opendocument.graphics application/vnd.oasis.opendocument.spreadsheet application/vnd.oasis.opendocument.text audio/ogg application/pdf application/vnd.ms-powerpoint image/svg+xml application/x-shockwave-flash image/tiff application/x-font-ttf audio/wav application/vnd.ms-write application/font-woff application/font-woff2 application/vnd.ms-excel;
    location ~ \.(css|htc|less|js|js2|js3|js4)$ {
        expires 31536000s;
        etag on;
        if_modified_since exact;
        try_files $uri $uri/ /index.php?$args;
    }
    location ~ \.(html|htm|rtf|rtx|txt|xsd|xsl|xml)$ {
        etag on;
        if_modified_since exact;
        try_files $uri $uri/ /index.php?$args;
    }
    location ~ \.(asf|asx|wax|wmv|wmx|avi|avif|avifs|bmp|class|divx|doc|docx|exe|gif|gz|gzip|ico|jpg|jpeg|jpe|webp|json|mdb|mid|midi|mov|qt|mp3|m4a|mp4|m4v|mpeg|mpg|mpe|webm|mpp|_otf|odb|odc|odf|odg|odp|ods|odt|ogg|ogv|pdf|png|pot|pps|ppt|pptx|ra|ram|svg|svgz|swf|tar|tif|tiff|_ttf|wav|wma|wri|xla|xls|xlsx|xlt|xlw|zip)$ {
        expires 31536000s;
        etag on;
        if_modified_since exact;
        try_files $uri $uri/ /index.php?$args;
    }
    add_header Referrer-Policy "no-referrer-when-downgrade";
# END Browser Cache

2.重新启动nginx服务

用命令 systemctl restart nginx重启nginx服务,再使用命令 systemctl status nginx查看nginx服务状态。

[root@hecs-288529 ~]# systemctl restart  nginx
[root@hecs-288529 ~]# systemctl status  nginx
● nginx.service - nginx
     Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; preset: disabled)

             └─5799 "nginx: worker process"

3.浏览网站测试

发现网页访问秒开，但是网页有部分图片无法显示。

打开EDGE浏览器的开发人员工具（其它浏览器也有类似工具），发现有部分图片资源请求的回应是404。

查看nginx的错误日志，发现有大量 No such file or directory的错误记录，正是回应404的部分图片资源请求。摘录其中一条错误日志如下：

2023/06/03 11:00:43 [error] 21996#0: *55 open() "/usr/local/nginx/html/wp-content/uploads/2023/05/Pasted-image-20230307220546-1536x864.png" failed (2: No such file or directory), client: 36.157.185.137, server: wslibai.com, request: "GET /wp-content/uploads/2023/05/Pasted-image-20230307220546-1536x864.png HTTP/2.0", host: "wslibai.com", referrer: "https://wslibai.com/technology/visual-studio-code-%e5%bc%80%e5%8f%91c-c%e7%8e%af%e5%a2%83%e6%90%ad%e5%bb%ba/"

经核实是请求资源的路径错误，原来是我的wordpress网站根目录已设置为html/wordpress，而上述新添加的location块中未配置root参数。

4.添加根目录参数设置

在以上新添加的几个location块中添加一行内容： root html/wordpress;，保存修改，重新启动nginx服务，问题解决。

location ~ \.(css|htc|less|js|js2|js3|js4)$ {
            root   html/wordpress;
            add_header    Cache-Control  max-age=360000;
            #expires 31536000s;
            etag on;
            if_modified_since exact;
            try_files $uri $uri/ /index.php?$args;
        }
        location ~ \.(html|htm|rtf|rtx|txt|xsd|xsl|xml)$ {
            root   html/wordpress;
            add_header    Cache-Control  max-age=no-cache;
            etag on;
            if_modified_since exact;
            try_files $uri $uri/ /index.php?$args;
        }
        location ~ \.(asf|asx|wax|wmv|wmx|avi|avif|avifs|bmp|class|divx|doc|docx|exe|gif|gz|gzip|ico|jpg|jpeg|jpe|webp|json|mdb|mid|midi|mov|qt|mp3|m4a|mp4|m4v|mpeg|mpg|mpe|webm|mpp|_otf|odb|odc|odf|odg|odp|ods|odt|ogg|ogv|pdf|png|pot|pps|ppt|pptx|ra|ram|svg|svgz|swf|tar|tif|tiff|_ttf|wav|wma|wri|xla|xls|xlsx|xlt|xlw|zip)$ {
            root   html/wordpress;
            add_header    Cache-Control  max-age=360000;
            #expires 31536000s;
            etag on;
            if_modified_since exact;
            try_files $uri $uri/ /index.php?$args;
        }
        add_header Referrer-Policy "no-referrer-when-downgrade";

细心的读者可能发现了expires参数已被替换为Cache-Control ，其实两个参数功能差不多，都是表示强缓存，但前者是http 1.0，后者是http1.1的，后者功能更强。如果两个参数都配置，起作用的是后者。具体含义可自行百度。同时，我将过期时间从原来的4个月修改为4天了（开发调试期间，设短一点）。

5.打开开发人员工具浏览网站测试验证

用EDGE浏览器打开网站页面，并打开开发人员工具，刷新页面，发现总请求128次，通过网络传输大小为59.6kB，资源实际大小为8MB。说明浏览器缓存已启用。
