Memcached¶
The Identity service authentication mechanism for services uses Memcached to cache tokens. The memcached service typically runs on the controller node. For production deployments, we recommend enabling a combination of firewalling, authentication, and encryption to secure it.
Install and configure components¶
Install the packages:
# yum install memcached python-memcached
Finalize installation¶
Start the Memcached service and configure it to start when the system boots:
# systemctl enable memcached.service # systemctl start memcached.service
