"Linux" "Services" "IaaS" Openstack-pike (5. Install memcached)

1. Introduction

1.1. Note: Because memcached does not have its own cluster scheme, so this step is very simple, direct installation can be enabled. The popular online is the use of magent, but also a scheduler and other software. Since OpenStack is self-balancing, this demo is not configured to be highly available
