You can edit this file to adjust the amount of memory used by Memcached, the port it listens on, and other settings. For example, to change the amount of memory used by Memcached to 128MB, you can modify the -m parameter as follows:
OPTIONS="-l 127.0.0.1 -U 11211 -m 128"
  1. Restart the Memcached service for the configuration changes to take effect:
sudo systemctl restart memcached

That’s it! Memcached is now installed and running on your Redhat/CentOS system. You can now configure your applications to use Memcached to improve their performance.
