WordPress NGINX WP Super Cache配置规则

我一直使用Web环境是LAMP，WP Super Cache运行起来是比较方便的。NGINX其实也可以安装WP Super Cache，NGINX配置如下：

server {
    server_name example.com www.example.com;
    root /var/www/example.com/htdocs;
    index index.php;

    access_log /var/log/nginx/example.com.access.log;
    error_log  /var/log/nginx/example.com.error.log debug;

    set $cache_uri $request_uri;

    # POST requests and URLs with a query string should always go to PHP
    if ($request_method = POST) {
        set $cache_uri 'null cache';
    }  
    if ($query_string != "") {
        set $cache_uri 'null cache';
    }   

    # Don't cache URIs containing the following segments
    if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php
                          |wp-.*.php|/feed/|index.php|wp-comments-popup.php
                          |wp-links-opml.php|wp-locations.php |sitemap(_index)?.xml
                          |[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {

        set $cache_uri 'null cache';
    }  
	
    # Don't use the cache for logged-in users or recent commenters
    if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+
                         |wp-postpass|wordpress_logged_in") {
        set $cache_uri 'null cache';
    }

    # Use cached or actual file if it exists, otherwise pass request to WordPress
    location / {
        try_files /wp-content/cache/supercache/$http_host/$cache_uri/index.html 
                  $uri $uri/ /index.php;
    }    

    location = /favicon.ico {
        log_not_found off; 
        access_log off;
    }

    location = /robots.txt {
        log_not_found off;
        access_log off;
    }

    location ~ .php$ {
        try_files $uri /index.php;
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        #fastcgi_pass 127.0.0.1:9000;
    }
	
    # Cache static files for as long as possible
    location ~*.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg
                 |jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid
                 |midi|wav|bmp|rtf)$ {
        expires max;
        log_not_found off;
        access_log off;
    }
}

之前做的Hyper Cache与WP Super Cache缓存性能对比测试是在LAMP下，不是NGINX下的，NGINX下晚些时候有服务器再做测试。
