In this article, we’ll explain how it is easy to install Memcached on Ubuntu 20.04.
Memcached is free and open-source, high-performance, distributed memory object caching system software. Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
- A Ubuntu 20.04 installed dedicated server or KVM VPS.
- A root user access or normal user with administrative privileges.
Let’s get started with the installation.
1. Keep the server updated
# apt update -y
# apt upgrade -y
2. Install Memcached
Run the following command to install Memcached with supporting utilities.
# apt install memcached libmemcached-tools
3. Start and enable memcached.service
After the installation, start and enable the memcached.service, using following commands:
# systemctl start memcached
# systemctl enable memcached
Run a status check by typing in the following command:
# systemctl status Memcached
In case, you want to configure Memcached, you will need to edit the configuration file. Go to /etc/memcached.conf and start editing the file.
# vi /etc/memcached.conf
One setting that you can change is the default IP address 127.0.0.1, which Memcached listens on. You can specify IP address listening by editing the following line in the config file.
After making the changes restart memcached.service
# systemctl restart memcached
In case, you are using firewall UFW, add port Memcached default port 11211 like shown below:
# ufw allow from 127.0.0.1 to any port 11211
That’s it. The installation has been completed.
