Code Issues Proposed changes
openstack-manuals/doc/install-guide/source/environment-memcached-obs.rst
Doug Hellmann c7bfdbb44f split install guide into separate files by OS 
Provide a script for interpreting the "only" directives and splitting
the existing content up into standalone files for each OS to make it
easier for project teams to copy the parts they need into their own
project documentation trees without requiring separate platform builds.

The files have been hand-edited to pass the niceness check and to allow
the install guide to build.

The script for building the guide has been changed to not build separate
copies per OS.

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
