Hi,
I'm having some trouble with horizon on centos 6.3. I've followed the
installation instructions at:
http://docs.openstack.org/essex/openstack-compute/install/yum/content/ch
_install-dashboard.html#dashboard-system-requirements.
I had this working, but following a reboot, horizon hasn't come right.
I've tried reinstalling it, but I'm getting nowhere. I've got memcached
running:
[root at wonky openstack-dashboard]# netstat -an | grep 11211
tcp 0 0 0.0.0.0:11211 0.0.0.0:*
LISTEN
tcp 0 0 :::11211 :::*
LISTEN
udp 0 0 0.0.0.0:11211 0.0.0.0:*
udp 0 0 :::11211 :::*
[root at wonky openstack-dashboard]# ps -ea | grep memcached
3318 ? 00:00:00 memcached
[root at wonky openstack-dashboard]# service memcached status
memcached (pid 3318) is running...
But with this config in my /etc/openstack-dashboard/local_settings file:
CACHE_BACKEND = 'memcached://127.0.0.1:11211/'
I get a django runtime error when I try to load the dashboard: Unable
to create a new session key.
I've seen others resolve this problem by installing or starting
memcached, but memcached is running in my environment.
Can anyone shed any light on how I can resolve this problem?
Here is the database stanza from the local_settings file:
# FIXME: We need to change this to mysql, instead of sqlite.
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'dash',
'USER': 'dash',
'PASSWORD': 'dash',
'HOST': 'localhost',
'default-character-set': 'utf8'
},
}
CACHE_BACKEND = 'memcached://127.0.0.1:11211/'
Thanks.
Cheers,
b
