# by Fotis Evangelou (Engintron)
#
# Updated: May 2018
#
# USAGE:
# Upload this file at the root (/) folder of your cPanel/WHM server (on CentOS 7)
# and make it executable with: $ chmod +x /memcached_installer_for_cpanel.sh
#
# Then execute it with:
# $ /memcached_installer_for_cpanel.sh
#
# To define a different cache pool size (e.g. 512M), execute with:
# $ /memcached_installer_for_cpanel.sh 512M
#
# Enjoy!

CACHE_SIZE="256M"
