Doug Hellmann e39304d4ae fix pdf build
The PDF build does not include content multiple times if the same file
is included in a toctree more than once. That means we need to
restructure the guide to handle the common parts differently. This
approach merges some of the previously split sections back together
using inline prose to indicate where minor variations apply for
different operating systems but retaining separate files for cases where
the differences are significant.

SUSE 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

  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 127.0.0.1"

      Note

      Change the existing line MEMCACHED_PARAMS="-l 127.0.0.1,::1".

Finalize installation

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

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