Introduction

Memcached is a high-performance, distributed memory caching system used to speed up dynamic web applications by alleviating database load. This guide will walk you through the installation of Memcached on Ubuntu 22.04, which can be efficiently hosted on a Windows VPS UK for enhanced performance and reliability.

Prerequisites

• An Ubuntu 22.04 server with root access
• Basic knowledge of Linux commands

Step 1: Update Your System

Start by updating your package index and upgrading any existing packages:

sudo apt update && sudo apt upgrade -y

Step 2: Install Memcached

To install Memcached, use the following command:

sudo apt install memcached libmemcached-dev -y

Step 3: Configure Memcached

Edit the Memcached configuration file to set the desired memory limit and other options:

sudo nano /etc/memcached.conf

Here are some key parameters you can modify:

• -m: Sets the memory limit (in MB) for caching. Default is 64MB.
• -p: Sets the port number. Default is 11211.
• -u: User that Memcached will run as. Default is nobody.

For example, to set a memory limit of 256MB, find the line that starts with -m and change it to:

-m 256

Step 4: Start Memcached Service

Start the Memcached service and enable it to run on boot:

sudo systemctl start memcached
sudo systemctl enable memcached

Step 5: Verify Memcached is Running

Check the status of the Memcached service:

sudo systemctl status memcached

You should see output indicating that Memcached is active and running.

Step 6: Testing Memcached

To test Memcached, you can use the following command to connect to it:

echo "stats" | nc 127.0.0.1 11211

This command should return statistics about the Memcached server, confirming that it is operational.
