OpenStack界面登录报错

1、OpenStack界面登录时，出现报错

2、修改文件/etc/openstack-dashboard/local_settings
SESSION_ENGINE = ‘django.contrib.sessions.backends.cache’

CACHES = {
‘default’: {
‘BACKEND’: ‘django.core.cache.backends.memcached.MemcachedCache’,
‘LOCATION’: ‘controller:11211’,
},
}
3、重启服务
systemctl restart memcached.service
service httpd restart
