Site environment: aaPanel Nginx 1.17 PHP 7.3 Add the following 4 rows to the top of the site configuration. fastcgi_cache_key "$scheme$request_method$host$request_uri"; fastcgi_cache_path /dev/shm/fastcgi-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m; fastcgi_cache_use_stale error timeout invalid_header http_500; fastcgi_ignore_headers Cache-Control Expires Set-Cookie; if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } Create a cache directory mkdir /dev/shm/fastcgi-cache Comment php configuration Add the following to the server field If you have ssl turned on, add it below #SSL-END 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/|index.php|sitemap(_index)?.xml") { set $skip_cache 1; } if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") { set $skip_cache 1; } location ~ [^/]\.php(/|$) { try_files $uri =404; fastcgi_pass unix:/tmp/php-cgi-73.sock; fastcgi_index index.php; include fastcgi.conf; add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload"; fastcgi_cache_bypass $skip_cache; fastcgi_no_cache $skip_cache; add_header X-Cache "$upstream_cache_status From $host"; fastcgi_cache WORDPRESS; add_header Cache-Control max-age=0; add_header Nginx-Cache "$upstream_cache_status"; add_header Last-Modified $date_gmt; add_header X-Frame-Options SAMEORIGIN; add_header X-Content-Type-Options nosniff; add_header X-XSS-Protection "1; mode=block"; etag on; fastcgi_cache_valid 200 301 302 1d; } location ~ /purge(/.*) { allow 127.0.0.1; allow "change_to_your_server_ip"; deny all; fastcgi_cache_purge WORDPRESS "$scheme$request_method$host$1"; } if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } Install and configure the (Nginx Helper) wp plugin. Since the cache path defined by the plugin author is /var/run/nginx-cache , we may customize the cache path according to the actual situation of the server. As a result, the difference of the cache path will cause the plugin to not find the cache file and delete it! Add the following code to the WordPress wp-config.php file Check whether the configuration takes effect

This is working, however the PURGE does not clear the cache. I have had to manually remove the files from this path to clear the cache: /dev/shm/fastcgi-cache Also let me know, why do we need to comment out PHP Conf files. I am using PHP 7.2 & Nginx 1.16, will there be any difference?

aaPanel_Jose In point number 6 we need to use this code and path to wp-config.php, and then PURGE button of nginx helper will work. define('RT_WP_NGINX_HELPER_CACHE_PATH', '/dev/shm/fastcgi-cache');

When I want to duplicate this procedure on multiple websites, what approach should be used? Since it is giving error message while saving config on another website. nginx: [emerg] "fastcgi_cache_key" directive is duplicate

can you make this as addon or default in next upgrade as cache is most require for wordpress sites

szone So if we need to use fastcgi caching on multiple sites, we need to follow this process: (you need to skip step number 1 from above guide) add the following code to nginx.conf located at this path /www/server/nginx/conf/ fastcgi_cache_key "$scheme$request_method$host$request_uri"; fastcgi_cache_path /dev/shm/fastcgi-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m; fastcgi_cache_use_stale error timeout invalid_header http_500; fastcgi_ignore_headers Cache-Control Expires Set-Cookie; if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } And add the following code to each site's config file: 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/|index.php|sitemap(_index)?.xml") { set $skip_cache 1; } if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") { set $skip_cache 1; } location ~ [^/]\.php(/|$) { try_files $uri =404; fastcgi_pass unix:/tmp/php-cgi-73.sock; fastcgi_index index.php; include fastcgi.conf; add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload"; fastcgi_cache_bypass $skip_cache; fastcgi_no_cache $skip_cache; add_header X-Cache "$upstream_cache_status From $host"; fastcgi_cache WORDPRESS; add_header Cache-Control max-age=0; add_header Nginx-Cache "$upstream_cache_status"; add_header Last-Modified $date_gmt; add_header X-Frame-Options SAMEORIGIN; add_header X-Content-Type-Options nosniff; add_header X-XSS-Protection "1; mode=block"; etag on; fastcgi_cache_valid 200 301 302 1d; } location ~ /purge(/.*) { allow 127.0.0.1; allow "change_to_your_server_ip"; deny all; fastcgi_cache_purge WORDPRESS "$scheme$request_method$host$1"; } if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); }

szone Yes, the configuration of the first step only needs to be configured once.

JAY I think this configuration can be added with an open button or other methods. We will join the development plan

what if i have a non wordpress site how to cache my site..

How to enable fastcgi cache for WordPress with aapanel

haivcci

fast-cgi cache is the important page cache method and aaPanel author even did not give the solution for two or more websites on this thread. Poor aaPanel. I will stop to try aaPanel here.

aaP_Rajib

aaPanel_Jose This post was very helpful. I did some modifications and finally managed to set fastcgi on multiple websites.

ccasalicchio

Is this still valid for aaPanel version 6.8.22, nginx 1.21.4, and PHP 7.4 ?

aaPanel_Kern

ccasalicchio
yes it works, you have to replace from 73 to 74 in above examples.

Syams

aaPanel_Jose What is benefit of FastCGI cache?

idwikat

is the Nginx Helper wp plugin necessary for fastcgi cache to work or it's just for the purge cache to work? because I do it manually anyway

dattrinh

Hi, I did follow your instruction and it worked, thanks for the tutorial.
But, I got a problem that is when I enable "Anti-XSS attack (Base directory limit)(open_basedir)" feature for the website, I can't do "Purge Cache" from the Nginx-Helper plugin, there was no-showed error, I clicked on it, and I check the cache folder in the server, the cached files were still there.
"Purge Cache" works well when I disable "Anti-XSS attack (Base directory limit)(open_basedir)".

So, is there any solution to that? I want to enable "Anti-XSS attack (Base directory limit)(open_basedir)"

Hello, try to add the relevant directory to the .uer.ini file

Josdansd

This doesn't work if Wordpress is in a subdirectory, what should be modified for it to work?

dattrinh

aaPanel_Kern Thank you! it works well now. 😀

I want to share my work here.
I did update the file: /www/server# vim panel/class/panelSite.py

As you can see in the picture, I added /dev/shm, /dev/shm is my cache path.

Do not forget to restart the panel to apply your change.

Josdansd

@aaPanel_Kern any advices to make the fastcgi cache works if wordpress is running in a subdirectory?

aaPanel_Kern

Josdansd
The same, except that the site data storage directory is different

Josdansd

aaPanel_Kern But I followed the same steps and I'm getting a 502 Nginx Error

aaPanel_Kern

Josdansd
It is recommended that you use Wordpress deploy for deployment and enable caching

Tried so many times, when we use Fast CGI cache with NGINX helper security headers are not detected.

aaPanel_Kern

aaP_hareeshnarayan1982
Hello, it is recommended to modify the configuration and add it yourself

aaP_hareeshnarayan1982

aaPanel_Kern

I had added the headers in site config. Here are the headers that i added in site config. Without NGINX cache (NGINX Helper) its working fine.
add_header X-XSS-Protection "1; mode=block";
add_header X-Frame-Options "ALLOW-FROM *";
add_header X-Content-Type-Options "nosniff" always;
add_header Referrer-Policy "strict-origin-when-cross-origin";
add_header Permissions-Policy "geolocation=(),midi=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),fullscreen=(self),payment=()";
add_header Content-Security-Policy "upgrade-insecure-requests";

Permission, referral and content security is what having problems.

aaP_hareeshnarayan1982
look confing PHP conf

aaP_hareeshnarayan1982

aaPanel_Kern
Checked

aaPanel_Kern

aaP_hareeshnarayan1982
/www/server/nginx/conf

Modify this file. Pay attention to backup first

aaP_hareeshnarayan1982

aaPanel_Kern Worked perfectly. Thanks for your help. I think you can add this into the guide.
