I am installing Openstack of Mitaka and Centos7.

When I add SESSION_ENGINE = 'django.contrib.sessions.backends.cache' in localsetting file as the installation file mentioned, I can't access the website of Openstack, the erros is as below: "Unable to create a new session key. " [Fri Mar 03 16:29:22.382562 2017] [:error] [pid 28850] RuntimeError: Unable to create a new session key. It is likely that the cache is unavailable.

but if I remove it, I can access the website by webrowsers but the speed is slow becausse no cache I guess, I want to know why? Thanks!

Check that memcached is actually running, and that it's listening on the correct IP (OPTIONS="-l ....) Also, did you update the CACHES section in local_settings?

CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller:11211',
    }

Thanks! I really config the caches and session according to installation document, so the configuration of caches is right, the service of httpd and memcached are all good, but it really doesn't work!

modify /etc/sysconfig/memcached -l 127.0.0.1 to management ip address of controller to solve it!
