Integrating memcached

As mentioned previously, it is up to you to decide whether to offer dedicated servers for memcached instances or not. The following example assumes a simple installation of memcached on cloud controller nodes running the Keystone service. So, do not forget to adjust your settings when installing memcached, including the IP addresses of cloud controllers:

  1. Install memcached on your first cloud controller, as follows:
    # yum install -y memcached python-memcache
The following steps can be performed on OpenStack Juno release and later. Make sure to check the appendix of the official OpenStack documentation if any module or directive is being deprecated or renamed http://docs.openstack.org/developer/keystone/configuration.html ...
