添加到站点conf文件中，如果不配置的话，访问时不会访问到wp super cache生成的html纯静态文件。

# Rest of your config lines above
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';
}

if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in") {

# Use cached or actual file if they exists, otherwise pass request to WordPress
location / {

}

修改后重启Nginx
