Memcached for SUSE

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:

    # zypper install memcached python-python-memcached

  1. Edit the /etc/sysconfig/memcached file and complete the following actions:

    • 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:

      MEMCACHED_PARAMS="-l 10.0.0.11"

      Note

      Change the existing line MEMCACHED_PARAMS="-l 127.0.0.1".

Finalize installation

  • Start the Memcached service and configure it to start when the system boots:

    # systemctl enable memcached.service
# systemctl start memcached.service
