Baota Panel Nginx FastCGI Cache Configuration Tutorial: Complete Guide to WordPress Website Acceleration (2026 Edition)

After installing a WordPress website, it's common to install a caching plugin to improve site speed.

Nginx FastCGI Page Cache is a technology that stores copies of PHP-generated web pages at the Nginx level. Compared to other WordPress caching plugins, using Nginx FastCGI Page Cache is faster and more efficient. The only difference is that it's a bit more complicated to configure.

Fortunately, there are now simple VPS management tools like Baota Panel (Baota Installation Tutorial) that even beginners can follow this tutorial to configure successfully.

Read carefully and operate meticulously. Follow Naiba step by step to enable Nginx FastCGI cache for WordPress.

Nginx FastCGI Cache Single Site Configuration Steps

Create Cache Folder

Enter the Baota Panel backend, go to the file management interface, and create an nginx folder under /www/wwwroot/[your website folder]/wp-content/cache/.

Modify Website NGINX Configuration File

Return to the website list, select the settings for the website you want to configure, the pop-up interface shown above, select the configuration file, and then add the following content.

#NGINX缓存配置1开始（blog.naibabiji.com替换为你网站正确文件夹名称）
fastcgi_cache_path /www/wwwroot/blog.naibabiji.com/wp-content/cache/ levels=1:2 keys_zone=blogcache:200m max_size=10g inactive=2h use_temp_path=off;
fastcgi_cache_key "$scheme$request_method$host$request_uri";
fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
#NGINX缓存配置1结束

Tip, if an error occurs when saving, indicating a conflict with /www/server/panel/vhost/nginx/0.fastcgi_cache.conf, simply delete the 0.fastcgi_cache.conf file.

Then, add the following code below the security certificate configuration:

#NGINX缓存配置2开始
set $skip_cache 0;

if ($request_method = POST) {
    set $skip_cache 1;
}
if ($query_string != "") {
    set $skip_cache 1;
}

if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|^/feed/*|/tag/.*/feed/*|index.php|/.*sitemap.*\.(xml|xsl)") {
    set $skip_cache 1;
}

if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
    set $skip_cache 1;
}
#NGINX缓存配置2结束

Modify PHP Software Configuration File

Using the Baota file function, enter the /www/server/nginx/conf folder, select the file corresponding to your own PHP version. For example, Naibabiji currently uses PHP 8.4, so select and edit the enable-php-84.conf file.

Add the following content before the last closing brace.

fastcgi_cache blogcache;
fastcgi_cache_valid 200 301 302 2h;
fastcgi_cache_use_stale error timeout updating invalid_header http_500 http_503;
fastcgi_cache_min_uses 1;
fastcgi_cache_lock on;
fastcgi_cache_bypass $skip_cache;
fastcgi_no_cache $skip_cache;
add_header X-FastCGI-Cache $upstream_cache_status;

After adding this code, return to the Baota backend, go to Software Store, then Installed, click on nginx to restart or reload the configuration. If there are no errors, it means the code was added correctly.

Test if Configuration is Effective

Use private/incognito mode or log out of your account, right-click in the browser and select Inspect Element or press F12, click on Network, select the URL you visited under Name, and then in the Headers, you can see X-Fastcgi-Cache HIT, which indicates the cache is working.

Alternatively, you can directly observe the cache folder you created. If new folders appear, it also indicates it's working.

Nginx FastCGI Cache Configuration for Multiple Sites on the Same Server

If your server contains multiple WordPress websites, and you need to configure Nginx FastCGI cache for all of them, you can follow the steps below.

1. Create an nginx folder in the directory of the website you want to configure, e.g., /www/wwwroot/blog.naibabiji.com/wp-content/cache/nginx

2. Open the nginx.php file under /www/server/nginx/conf, and insert the following code below 'access_log off;' (replace the URL with your own).

# FastCGI缓存配置 - WordPress网站专用
        # blog.naibabiji.com缓存区域
        fastcgi_cache_path /www/wwwroot/blog.naibabiji.com/wp-content/cache/nginx 
                          levels=1:2 
                          keys_zone=blog_cache:100m 
                          max_size=2g 
                          inactive=2h 
                          use_temp_path=off;
        
        # wordpressjc.com缓存区域
        fastcgi_cache_path /www/wwwroot/wordpressjc.com/wp-content/cache/nginx 
                          levels=1:2 
                          keys_zone=wordpressjc_cache:100m 
                          max_size=2g 
                          inactive=2h 
                          use_temp_path=off;
        
        # quhenet.com缓存区域
        fastcgi_cache_path /www/wwwroot/quhenet.com/wp-content/cache/nginx 
                          levels=1:2 
                          keys_zone=quhenet_cache:100m 
                          max_size=2g 
                          inactive=2h 
                          use_temp_path=off;
        
        # FastCGI缓存相关变量设置
        fastcgi_cache_key "$scheme$request_method$host$request_uri";
        fastcgi_cache_use_stale error timeout invalid_header http_500;

Tip, if an error occurs when saving, indicating a conflict with /www/server/panel/vhost/nginx/0.fastcgi_cache.conf, simply delete the 0.fastcgi_cache.conf file.

3. Create a wordpress-fastcgi-cache.conf file in the /www/server/nginx/conf folder with the following content:

# WordPress FastCGI缓存配置模板
# 适用于所有WordPress网站的通用缓存规则

# 设置不缓存的条件
set $skip_cache 0;

# POST请求不缓存
if ($request_method = POST) {
    set $skip_cache 1;
}

# URL包含查询字符串不缓存
if ($query_string != "") {
    set $skip_cache 1;
}

# WordPress管理后台和特殊页面不缓存
if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|^/feed/*|/tag/.*/feed/*|index.php|/.*sitemap.*\.(xml|xsl)") {
    set $skip_cache 1;
}

# 已登录用户不缓存
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
    set $skip_cache 1;
}

# WooCommerce相关页面不缓存（如果有电商功能）
if ($request_uri ~* "/(cart|my-account|checkout|addons)") {
    set $skip_cache 1;
}

# 包含购物车Cookie不缓存
if ($http_cookie ~* "woocommerce_items_in_cart|woocommerce_cart_hash") {
    set $skip_cache 1;
}

4. Still in the /www/server/nginx/conf directory, create the corresponding enable-php-84.conf files (the file corresponding to the PHP version used by the website) for each website you need to configure. The filenames can be referenced from Naiba's settings:

• enable-php-84-cache-quhenet.conf
• enable-php-84-cache-wordpressjc.conf
• enable-php-84-cache-blog.conf

After creation, each file's code has only one difference. The complete code is as follows:

location ~ [^/]\.php(/|$) {
    try_files $uri =404;
    fastcgi_pass  unix:/tmp/php-cgi-84.sock;
    fastcgi_index index.php;
    include fastcgi.conf;
    include pathinfo.conf;
    
    # FastCGI缓存配置（替换下方blog_cache为第2步创建的keys_zone值）
    fastcgi_cache blog_cache;
    fastcgi_cache_valid 200 301 302 2h;
    fastcgi_cache_use_stale error timeout updating invalid_header http_500 http_503;
    fastcgi_cache_min_uses 1;
    fastcgi_cache_lock on;
    fastcgi_cache_bypass $skip_cache;
    fastcgi_no_cache $skip_cache;

    # 忽略上游的缓存控制头（重要！）
    fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
    
    # 添加缓存状态头部信息（用于调试）
    add_header X-FastCGI-Cache $upstream_cache_status;
    add_header X-Cache-Skip $skip_cache;
}

5. Enter the /www/server/panel/vhost/nginx folder and edit the corresponding virtual host configuration file.

Replace the existing line 'include enable-php-84.conf;' with the following content.

# WordPress FastCGI缓存配置 - 必须在PHP配置之前
    include /www/server/nginx/conf/wordpress-fastcgi-cache.conf;
    include enable-php-84-cache-blog.conf;
# 上面这个php文件记得修改为你网站对应的文件

6. After completing the operations, restart nginx, test on the frontend, or directly check if new folders appear in the cache directory.

How to Clear Cache

Website backend, Plugin, install plugin, search for „Nginx cache“, install and activate.

Then go to the plugin settings, and fill in the input box after Cache Zone Path with your cache directory /www/wwwroot/blog.naibabiji.com/wp-content/cache/nginx.

Working with Other Plugins

To further improve website access speed and performance, we can also use it in conjunction with the following plugins.

1. Redis Object Cache

To use this plugin, first go to the Baota Panel backend, App Store, Installed, select the PHP version your website is using, install the redis extension, and then visitors can use it.

2. Autoptimize

This plugin can compress and integrate static resources.

No need to install other caching plugins, because the webpage already uses Nginx FastCGI caching. Installing additional caching plugins may have no effect and could even cause conflicts.
