[HOWTO] FASTCGI CACHE WORDPRESS Topic is solved

[valentine]

NGINX + PHP-FPM + WORDPRESS + NGINX CACHE SNIPER
I found a good solution to cache wordpress.

Nginx includes a FastCGI module which has directives for caching dynamic content that are served from the PHP backend. Setting this up removes the need for additional page caching solutions like reverse proxies (think Varnish) or application specific plugins (Super Cache). Content can also be excluded from caching based on the request method, URL, cookies, or any other server variable.

Cache Sniper for Nginx works as it should only if script have permissions to cache files and folders. To make it works you have to change the web user (%user%) to www-data which is the default user that nginx uses. Then your PHP script run through php-fpm will have the appropriate permissions and will be able to delete the cache.

Go to /usr/local/vesta/data/templates/web/php-fpm and make copy socket.tpl to www-data-socket.tpl
Open terminal:

Code: Select all

cd /usr/local/vesta/data/templates/web/php-fpm/
cp socket.tpl www-data-socket.tpl
sudo chmod 664 www-data-socket.tpl
nano www-data-socket.tpl

Find:

Code: Select all

user = %user%
      group = %user%

      listen.owner = %user%
      listen.group = www-data

and change with:

Code: Select all

                      user = www-data
                               group = www-data

                               listen.owner = %user%
                               listen.group = www-data
                               listen.mode = 0660

Go to /usr/local/vesta/data/templates/web/nginx/php-fpm and make copy wordpress2_rewrite.tpl, wordpress2_rewrite.stpl to wordpress2_rewrite_nginx_sniper.tpl, wordpress2_rewrite_nginx_sniper.stpl

Code: Select all

cd /usr/local/vesta/data/templates/web/nginx/php-fpm/
cp wordpress2_rewrite.tpl wordpress2_rewrite_nginx_sniper.tpl
cp wordpress2_rewrite.stpl wordpress2_rewrite_nginx_sniper.stpl
sudo chmod 664 wordpress2_rewrite_nginx_sniper.*

Code: Select all

nano wordpress2_rewrite_nginx_sniper.tpl

and after

Code: Select all

nano wordpress2_rewrite_nginx_sniper.stpl

At the beginning add

Code: Select all

fastcgi_cache_path /var/cache/nginx/fastcgi_cache/%domain%/ levels=1:2 keys_zone=%domain%:100m inactive=60m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";
add_header X-Cache $upstream_cache_status;

Next, move the location directive that passes PHP requests to php-fpm. Inside "location ~ .php$ { }" add the following lines.

Code: Select all

fastcgi_cache_valid 200 301 302 60m;
fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
fastcgi_cache %domain%;

Some dynamic content such as authentication required pages shouldn't be cached.
Such content can be excluded from being cached based on server variables.
Here is a configuration which must be used in the server{ } context.

Code: Select all

#Cache everything by default
set $skip_cache 0;

    # POST requests and urls with a query string should always go to PHP
    if ($request_method = POST) {
        set $skip_cache 1;
    }

    #Don't cache if the URL contains a query string
    if ($query_string != "") {
        set $skip_cache 1;
    }   

    # Don’t cache uris containing the following segments
    if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
        set $skip_cache 1;
    }   

    # Don’t use the cache for logged in users or recent commenters
    if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
        set $skip_cache 1;
    }
    
    # Skip cache on WooCommerce pages
    if ($request_uri ~* "/store.*|/cart.*|/my-account.*|/checkout.*|/addons.*") {
        set $skip_cache 1;
    }

To apply the "$no_cache" variable to the appropriate directives, place the following lines inside location ~ .php$ { }

Code: Select all

fastcgi_cache_bypass $skip_cache;
fastcgi_no_cache $skip_cache;

All together looks like:Show

fastcgi_cache_path /var/cache/nginx/fastcgi_cache/%domain%/ levels=1:2 keys_zone=%domain%:200m inactive=120m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";

add_header X-Cache $upstream_cache_status;

server {
listen %ip%:%web_port%;
server_name %domain_idn% %alias_idn%;

#Cache everything by default

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

#Don't cache if the URL contains a query string
if ($query_string != "") {
set $skip_cache 1;
}

# Don’t cache uris containing the following segments
if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
set $skip_cache 1;
}

# Don’t use the cache for logged in users or recent commenters
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
set $skip_cache 1;
}

# Skip cache on WooCommerce pages
if ($request_uri ~* "/store.*|/cart.*|/my-account.*|/checkout.*|/addons.*") {
set $skip_cache 1;
}

include /etc/nginx/conf.d/phppgadmin.inc*;
include /etc/nginx/conf.d/webmail.inc*;

include %home%/%user%/conf/web/nginx.%domain_idn%.conf*;
}

Make your cache directory
Open terminal:

Code: Select all

mkdir -p  /var/cache/nginx/fastcgi_cache
chown -R www-data /var/cache/nginx/fastcgi_cache
chmod 700 /var/cache/nginx/fastcgi_cache

and change owner to youruser web folder

Code: Select all

chown -R www-data:www-data /home/youruser

Open terminal: save, update and restart

Code: Select all

v-update-web-templates
service nginx configtest
service nginx restart
systemctl restart php7.2-fpm

Open Wordpress Plugins (yourdomain.php/wp-admin/plugins.php)
Add and activate Cache Sniper for Nginx

And set your fastcgi_cache_path to plugin
Cache Path settings /var/cache/nginx/fastcgi_cache/yourdomain.com
Cache Levels settings 1:2


You can controll if you cache or not, and how long you cache page by page
Homepage cache already controlled by plugin last update.

So, open index.pxp and put in the beginning to be sure that your main page cache renew every 10 min.

Code: Select all

<?php
if (is_front_page() ) {
   header("X-Accel-Expires: 600"); // cache main page for a while the big 10 minutes
} 
?>
<html>
<body>

Good luck with everything!

Can you explain this line

Code: Select all

Next, move the location directive that passes PHP requests to php5-fpm. Inside "location ~ .php$ { }" add the following lines.

Of course, you can check spoiler, where all lines together. But I have php 7.2 onboard.

[xorro]

I am sorry for my short question before what i wanted to ask was in which file do we need to put this code?

[valentine]

vesta php-fpm templates: wordpress2_rewrite_nginx_sniper.tpl and wordpress2_rewrite_nginx_sniper.stpl

Code: Select all

cd /usr/local/vesta/data/templates/web/nginx/php-fpm/
cp wordpress2_rewrite.tpl wordpress2_rewrite_nginx_sniper.tpl
cp wordpress2_rewrite.stpl wordpress2_rewrite_nginx_sniper.stpl
sudo chmod 664 wordpress2_rewrite_nginx_sniper.*

UPDATED. U MAKE MISTAKE IN MANUAL. $skip_cache/$no_cache

[valentine]

UPDATE. ADD

Code: Select all

fastcgi_ignore_headers Cache-Control Expires Set-Cookie;

BECAUSE viewtopic.php?f=29&t=15764&p=64967&hili ... che#p64967

[valentine]

Also use this for browser cache:

Code: Select all

location ~* ^.+\.(jpeg|jpg|png|gif|bmp|ico|svg|css|js|eot|otf|woff|woff2|ttf|ogg)$ {
expires max;
fastcgi_hide_header "Set-Cookie";
}

You want your site to be fast, so you added caching… but now you have a new challenge that you have content that shouldn’t be caching such as ads, feeds, rotating ads, videos, shopping carts and more..

With No Cache AJAX Widgets, you simply drag and drop the new AJAX powered widgets to any widget area/s, add your content and you are done. No more messing with your theme files, functions.php, fragmented caching, mfunc and others or excluding an entire page from caching.
