Memcached is a memory object caching system specifically designed to enhance the speed of dynamic web applications by reducing the load of the database server.

Install Memcached on Ubuntu 22.04 LTS

Step 1. First, before you start installing any package on your Ubuntu server, we always recommend making sure that all system packages are updated.

sudo apt update
sudo apt upgrade
sudo apt install software-properties-common apt-transport-https wget

Step 2. Install Memcached on Ubuntu.

Memcached installation is quite easy and straightforward since the Memcached package is accessible in the repositories of the majority of Linux distributions. To install Memcached, enter the following command:

sudo apt install memcached libmemcached-tools

Now you can verify that Memcached was installed:

memcached --version

To start Memcached, run the following systemctl command:

sudo systemctl enabled memcached --now
sudo systemctl start memcached

In addition, you can also enable Memcached for PHP applications. It can easily be installed using the APT package manager. Here is the command:

sudo apt install php-memcached

Step 3. Configure Memcached on Ubuntu.

For configuration, we will open its config file using your favorite text editor:

sudo nano /etc/memcached.conf

Leave as the default unless you have internal IP on a local network or external IP from outside; you must modify the default IP address from to the new IP address:


Next, recommended disabling UDP:

-U 0

Now change the default 64MB memory allocation is recommended as this isn’t much for larger websites, and you will not see much benefit using Memcached:

-m 2000

Save the file, then exit and restart your Memcached instance:

sudo systemctl restart memcached

Step 4. Configure Firewall.

Don’t forget to allow TCP port 11211 in your server firewall. If you are using Ubuntu’s UFW firewall then you have to open the port in that for remote connection; use the given command:

sudo ufw allow 11211/tcp

Step 5. Memcached Command line.
