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
--------------------------------

#. Install the packages:

   .. code-block:: console

      # zypper install memcached python-python-memcached

   .. end

2. 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:

     .. code-block:: none

        MEMCACHED_PARAMS="-l 127.0.0.1"

     .. end

     .. 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:

  .. code-block:: console

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

  .. end

Update install instructions for memcached
Update install instructions for memcached

The OBS install instructions for memcached incorrectly instructed the
user to configure memcached to listeon on the localhost address. It
should be configured to use the management IP address of the
controller.
