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..

can you helpme on this to add cache on non wordpress site.

How to enable fastcgi cache for WordPress with aapanel

aaP_raha_ab1988

Now the config saved whiteout error but in testing with browser, I couldn't find any FastCGI cache

aapanel_user

aaP_raha_ab1988 Cache does not work for logged in users. Check in private browsing mode.

aaP_raha_ab1988

aapanel_user Yes you right , I cheek that and then works perfect ,
Now for wordpress which plugin? WP-Rocket or WP-fastest cache?

aapanel_user

aaP_raha_ab1988 I didn't use any of them. And if you use fastcgi cache you don't really need cache plugins.

aaP_raha_ab1988

aapanel_user Dos that minifiy java script and css and html ?

Free

aaP_raha_ab1988 For wordpress with fastcgi cache i recommend autoptimize work well together.

aapanel_user

aaP_raha_ab1988 No. I also recommend autoptimize.

I am trying to setup my second site for fastcgi-cache
So I can just use the same directory ?
mkdir /dev/shm/fastcgi-cache
or I need to create new directory for new site ?
mkdir /dev/shm/fastcgi-cache2

and new config site
define('RT_WP_NGINX_HELPER_CACHE_PATH', '/dev/shm/fastcgi-cache2');

????

aapanel_power

lucius100 Caching on local disk is not as fast as putting it in an in-memory database like Redis|MongoDB|Memcached. You can try using

aapanel_power
With all due respect, that is not what @lucius100 is asking. I also would like to know the answer to his question.
Besides that, I don't believe that Redis should be used for full page caching, but Fastcgi.

Kind greetings,
Jimmy

lucius100

JimmyBobsa I think we can mix the folder for both site, but purge cache sure will clear the cache for 2 sites, that's why we need to create second folder maybe ?

@aapanel_power I just want to use fastcgi on local disk, no enough memory for redis,etc.

JimmyBobsa

lucius100 but purge cache sure will clear the cache for 2 sites

Correct. I have 11 WP sites running on a 4GB VPS and all sites are really fast. But when 1 sites clears the cache, cache is purched for all sites. So 1 dir per website is the best idea indeed. Could not find how to make it work like that.

lucius100

JimmyBobsa Try make change to directory in step 1,2,6

/dev/shm/fastcgi-cache

make it more memorable, if website is example.com try use folder
/dev/shm/example

In theory, it should work.

JimmyBobsa

lucius100 In theory, it should work.

Yep, but it doesn't 😀
I have tried different way's, but the cache dir stay's empty. I tried with PHP 7.3/7.4 and 8

lucius100

JimmyBobsa I tried it just now, and it doesn't work lol.

ERROR:
nginx: [emerg] "fastcgi_cache_key" directive is duplicate in /www/server/panel/vhost/nginx/example.com.conf:1
nginx: configuration file /www/server/nginx/conf/nginx.conf test failed

I can't even use same setting for second site, it seems like fastcgi caching only can for 1 website.

So right now, all your website no caching ?
I just migrated from OLS to nginx, there's no way I gonna back again T_T
Really hope there's solution for fastcgi caching 2 or more website

Free

lucius100 For the second site change with /dev/shm/nginx-cache try this.
