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.

Debian 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:
# apt install memcached python-memcache

  1. 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
