Assumption:

1. You already installed PHP, MySQL, Nginx & Postfix
2. You already installed a fresh WordPress or moved an existing WordPress to current server

Based on these assumptions, we will jump to directly a WordPress-Nginx configuration part.

Standard WordPress-Nginx configuration with WP Super cache support:

As you are getting into Nginx, I hope you don’t need my help with configuring WP Super Cache plugin.

Still, make sure you are using “Use mod_rewrite to serve cache files. (Recommended)” option under “Advanced” tab.

Following configuration supports:

1. Static Page Caching using Disk
2. Direct browser cache for static content like images, js, css, etc

# WP Super Cache 设置.
# Designed to be included from a 'wordpress-ms-...' configuration file.
set $cache_uri $request_uri;

# POST 的请求和带参数的请求都通过php处理
if ($request_method = POST) {
        set $cache_uri 'null cache';
}
   
if ($query_string != "") {
        set $cache_uri 'null cache';
}   

# 以下文件不缓存
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';
}   

#对于已登录用户不缓存
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in") {
        set $cache_uri 'null cache';
}


# 当其他连接访问Wordpress的时候通过下面的路径找到缓存文件的地址,访问缓存页面
location / {
        try_files /wp-content/cache/supercache/$http_host/$cache_uri/index.html $uri $uri/ /index.php?$args ;
}   
location = /favicon.ico { log_not_found off; access_log off; }
location = /robots.txt  { log_not_found off; access_log off; }
 # 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;
   }

Note:

Don’t Forget:

Always test your Nginx configuration and then reload it. All changes to Nginx config must be followed with these commands:

nginx -t && service nginx reload

Important Note:

WP Super Cache caching will conflict with plugins that uses query vars. WooCommerce is an example known plugin known to work with above configuration. Reason is following line:

try_files /wp-content/cache/supercache/$http_host/$cache_uri/index.html $uri $uri/ /index.php ;

It doesn’t passes $args to /index.php. If you set last try_files argument to /index.php?$args as with other WordPress-Nginx configuration, WP Super Cache, itself will break!
