A Complete Guide to Installing Memcached on Amazon Linux 2023

How to Install Memcached on Amazon Linux 2023

Memcached is a popular in-memory caching system that can greatly improve the performance of your web applications. In this guide, we will walk you through the steps to install Memcached on Amazon Linux 2023.

Step 1: Update System Packages

Before we begin the installation process, let’s make sure our system packages are up to date. Open your terminal and run the following command:

sudo yum update -y

This command will update all the installed packages on your Amazon Linux system.

Step 2: Install Memcached

Now that our system is up to date, we can proceed with the installation of Memcached. Run the following command in your terminal:

sudo yum install memcached -y

This command will download and install Memcached on your system.

Step 3: Start and Enable Memcached Service

After the installation is complete, we need to start the Memcached service and enable it to start automatically on system boot. Run the following commands:

sudo systemctl start memcachedsudo systemctl enable memcached

These commands will start the Memcached service and configure it to start on system boot.

Step 4: Configure Memcached

By default, Memcached listens on the loopback interface (127.0.0.1) and uses the default port 11211. If you want to change these settings, you can edit the Memcached configuration file located at /etc/sysconfig/memcached. Open the file using a text editor:

sudo vi /etc/sysconfig/memcached

Inside the file, you can modify the OPTIONS variable to specify the listening IP address and port. For example, to make Memcached listen on all interfaces and use port 12345, you can set the following:

OPTIONS="-l 0.0.0.0 -p 12345"

Save the file and exit the text editor.

Step 5: Test Memcached

Now that Memcached is installed and configured, let’s test if it’s working correctly. Run the following command in your terminal:

echo "stats" | nc 127.0.0.1 11211

If Memcached is running properly, you should see a list of statistics related to the Memcached server.
