Memcached is a high-performance, distributed memory object caching server that stores data in memory to reduce the number of times an external database or an API must be accessed. Here's how you can install Memcached on CentOS 7:
sudo yum update
sudo yum install memcached sudo yum install libmemcached-tools
sudo systemctl start memcached sudo systemctl enable memcached
sudo systemctl status memcached
This will cause Memcached to listen on all available network interfaces.
sudo systemctl restart memcached
That's it! You have successfully installed and configured Memcached on CentOS 7.
