Memcached is an open-source, high-performance, distributed memory caching system that helps improve the speed of dynamic web applications by reducing database load. In this guide, we’ll walk you through how to install and configure Memcached on Ubuntu 22.04. For improved performance and scalability, it’s highly recommended to host your Memcached setup on a WindowsVPS. A VPS server ensures you have the dedicated resources needed to handle high-volume caching operations effectively.

Step 1: Update Your VPS Server

Before installing Memcached, ensure that your VPS server is up to date. Run the following commands to update your system:

sudo apt update && sudo apt upgrade -y

Using a WindowsVPS provides you with the necessary performance enhancements and dedicated resources required for a stable caching solution.

Step 2: Install Memcached

Memcached is available in the default Ubuntu 22.04 repositories, making it easy to install. Run the following command to install Memcached and its associated tools:

sudo apt install memcached libmemcached-tools -y

This command installs both the Memcached server and the tools you can use to manage it.

Step 3: Configure Memcached

After Memcached is installed, you can configure it to suit your specific needs. The default configuration file is located at /etc/memcached.conf. Open this file with a text editor:

sudo nano /etc/memcached.conf

Here are some key settings to consider:

• -m: Specifies the amount of memory allocated for Memcached (in megabytes). The default is 64MB, but you can adjust this depending on your server’s resources. For example, to allocate 128MB of memory, change this line to:

-m 128

• -l: Defines the IP address Memcached listens on. By default, it is set to 127.0.0.1 (localhost). If you want Memcached to be accessible remotely, you can change this to your VPS server's IP address:

-l your-server-ip

• -p: Specifies the port Memcached listens on (default is 11211). You can change this port if needed.

After making the changes, save the file and exit the text editor.

Step 4: Start and Enable Memcached

Once the configuration is complete, you can start the Memcached service and enable it to start automatically at boot:

sudo systemctl start memcached
sudo systemctl enable memcached

To check the status of the Memcached service, use the following command:

sudo systemctl status memcached

Step 5: Verify Memcached Installation

To verify that Memcached is running correctly, you can use the memcached-tool to check its status. Run the following command:

memcached-tool 127.0.0.1 stats

This will display a list of statistics about Memcached, including memory usage and cache hit rates, helping you monitor performance.

Step 6: Configure a Firewall Rule (Optional)

If you are using a firewall on your VPS server, you may need to open Memcached's default port (11211) to allow external connections. If you're using UFW (Uncomplicated Firewall), you can open the port with this command:

sudo ufw allow 11211

However, it’s generally recommended to keep Memcached accessible only locally unless needed. Opening ports can expose the service to external threats, so secure connections with additional measures if external access is required.

Step 7: Use Memcached in Your Applications

Now that Memcached is installed and running, you can integrate it into your applications. Many popular web platforms like WordPress, Drupal, and frameworks such as Laravel support Memcached either natively or through plugins, allowing them to leverage caching for faster database query responses.

To optimize the caching performance of your web applications, hosting your setup on a WindowsVPS will ensure a more efficient caching system. A VPS server provides better resource management and is scalable as your project grows, ensuring that your caching system can handle increasing traffic and demand.

Conclusion

Installing Memcached on Ubuntu 22.04 is a simple and effective way to improve your web application's performance by reducing database load and speeding up data retrieval. Hosting Memcached on a WindowsVPS ensures that your caching solution has the dedicated resources needed to maintain optimal performance under heavy traffic or large data volumes.
