Check Memcached

This guide explains how to manage Memcached and particularly how to determine if this memory caching system is functioning correctly on your hosting.

Prerequisites

install Memcached on Managed Cloud Server

Check Memcached Execution

To verify Memcached is running correctly:

Copy the following code into a PHP file:

                        // connect to the local memcache server
$fp = fsockopen("localhost", 11211);
if ($fp) {
// request stats
fwrite($fp, "stats\n");
while (!feof($fp)) {
$buf = rtrim(fgets($fp));
if (preg_match('/^STAT curr_items ([0-9]+)$/', $buf, $matches)) {
// number of stored items
print $matches[1] . PHP_EOL;
} elseif (preg_match('/(END|ERROR)/', $buf)) {
// end of stats
break;
}
}
fclose($fp);
} else {
print "Error: cannot connect to local memcached server: $!" . PHP_EOL;
}

Upload the PHP file to your hosting
Execute the PHP file

The script will return the number of items cached in the server's memory.

Enable Memcached on a CMS

Prestashop

The native integration of Memcached into the Prestashop application simplifies its configuration. To enable it:

Access your Prestashop admin area
Go to the Advanced settings tab
Select Performance
Choose Yes from the dropdown under Use cache in the Cache section
Select CacheMemcached
Add a server by providing the required information such as
1. IP address: 127.0.0.1
2. Port: 11211
3. Weight: 1

You can test the information by clicking the "Test server" button before saving it at the bottom of the "Cache" section.

Once this step is completed, your PrestaShop application is ready to use Memcached to cache certain API calls, database calls, and objects.
