Lately the WordPress “Site Health” tool is reporting Object Cache as “Recommended”. Using memcache is one of the most popular solution for this case.

Here are some initial notes:

• php-memcache is a PECL extension;
• memcached is a service;
• php-memcache and php-memcached are two different PECL extensions. Don’t confuse them;
• As of this writing php-memcache 8 is available only for PHP 8+. If your environment still uses PHP 7.4 please remember that it has reached End of Life in 28 Nov 2022;
• Enabling Object Cache will increase memory usage (RAM) on your machine;
• It is mandatory for your users to define a private WP_CACHE_KEY_SALT key in their wp-config.php file. The value must be unique for each WordPress install. This helps prevent cache pollution when multiple WordPress installs are using the same memcached server. Not defining a key will have unpredictable results.

This tutorial implies that you are:

• Fully understanding what you’re doing and not just copy/pasting commands;
• Using Plesk on Debian, but this can be easily adapted to RPM-based distros;
• Installing php-memcache for PHP 8.1, but feel free to replace 8.1 with any other PHP 8.X version that you have installed on your Plesk machine;

Now let’s get to work.

Users coming from cPanel are used to access their account via the /cpanel and/or /whm URLs. Unfortunately Plesk’s login method is to access port 8443 which posts an invalid, self-signed, SSL certificate. As a result clients/visitors are usually scared to access such links, as all modern browsers block invalid SSL certificates by default or post big warnings.

The most easy fix is, as of this writing, to redirect port 8443 to Plesk hostname, which normally provides a valid SSL certificate and doesn’t uses a non-standard port. The client/visitor should simply access the /plesk URL and get redirected to wherever necessary. Also this helps providers redirect /cpanel and /whm to the new URL, pointing legacy users to the right place.

Dumitru era un om ca oricare altul. Fără speranță de foarte bine, fără așteptări de foarte rău.

Își păstra amintirile în poze. Își trăia viața pe casete video. Își rescria viața pe aceleași casete, la infinit, căutând parcă momentul perfect pe care să-l lase ca piatră de hotar urmașilor. Chiar și acum îmi aduc aminte cum își retrăia obsesiv, aproape în fiecare seară, într-o totală solitudine, propria-i viață.

Dumitru a trăit inspirând bunătate și expirând egoism. În final a pierdut totul. A câștigat însă ceea ce a căutat cu atâta stoicism: singurătate.

Nu l-am condus pe ultimul drum, l-ar fi parcurs oricum singur. Nu i-am oferit acest ultim gest deoarece am vrut ca imaginea singurătății lui să se oglindească, în amintirea și inima mea, până la final.

Nu muri ca Dumitru.
