Matthew Kassawara 6c185febf6 Install: Environment updates for Mitaka 
Update environment configuration for Mitaka.

1) Change SQL database configuration file name to
   something less clunky.
2) Improve consistency of SQL database configuration
   among distributions.
3) Change RDO to use the PyMySQL library.
4) Add pre-release package repositories for testing
   purposes. Remove after release of Mitaka packages.
5) Move Memcached content from keystone because all
   services use it, but in a different way than in
   Liberty.

Memcached

The Identity service authentication mechanism for services uses Memcached to cache tokens. For production deployments, we recommend enabling a combination of firewalling, authentication, and encryption to secure it.

Install and configure components

  1. Install the packages:

    ubuntu

    # apt-get install memcached python-memcache

    rdo

    # yum install memcached python-memcached

    obs

    # zypper install memcached python-python-memcached

ubuntu

  1. Edit the /etc/memcache/memcached.conf file and configure the service to use the management IP address of the controller node to enable access by other nodes via the management network:

    -l 10.0.0.11

    Note

    Change the existing line with -l 127.0.0.1.

Finalize installation

ubuntu or debian

  • Restart the Memcached service:

    # service memcache restart

rdo or obs

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

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