一、安装 Nginx Helper 插件
Enable Nginx Map.选项保存，即可看到插件为我们生成的映射关系文件信息。
二、修改网站配置文件
以宝塔面板为例，在网站配置文件server区域上方添加下方代码，并修改引入 Nginx Helper 插件生成的映射关系文件。
这是子目录的：
复制
<code><span class="pln">map $uri $blogname </span><span class="pun">{</span>
<span class="pun">~^(?<</span><span class="pln">blogpath</span><span class="pun">></span><span class="str">/[^/]+/</span><span class="pun">)</span><span class="pln">files</span><span class="pun">/(.*)</span><span class="pln"> $blogpath </span><span class="pun">;</span>
<span class="pun">}</span><span class="pln">
map $blogname $blogid </span><span class="pun">{</span>
<span class="kwd">default</span> <span class="pun">-</span><span class="lit">999</span><span class="pun">;</span><span class="pln">
include </span><span class="pun">映射文件路径.</span><span class="pln">conf</span><span class="pun">;</span>
<span class="pun">}</span></code>
这是子域名的：
复制
<code><span class="pln">map $http_host $blogid </span><span class="pun">{</span>
<span class="kwd">default</span> <span class="pun">-</span><span class="lit">999</span><span class="pun">;</span><span class="pln">
include </span><span class="pun">映射文件路径.</span><span class="pln">conf</span><span class="pun">;</span>
<span class="pun">}</span></code>
保存完成后应如下图所示：
三、设置 Nginx 伪静态规则
还是以宝塔面板为例，打开网站的伪静态配置页面，输入下方代码：
这是子目录的：
复制
<code><span class="com"># 避免 PHP 读取静态文件</span><span class="pln">

四、大功告成
如果你有使用 WP-Super-Cache 或者 W3 Total Cache ，可前往https://wordpress.org/support/article/nginx/#wp-super-cache-rules以获取它们所使用的 Nginx 规则，替换上述规则相应的部分，这将使缓存绕过PHP以达到性能最大化。
