Memcached for Ubuntu

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

  1. Install the packages:

    # apt install memcached python-memcache

  2. Edit the /etc/memcached.conf file and configure the service to use the management IP address of the controller node. This is to enable access by other nodes via the management network:

    -l 10.0.0.11

    Note

    Change the existing line that had -l 127.0.0.1.

Finalize installation

  • Restart the Memcached service:

    # service memcached restart
