OpenStack: Keystone and nova-network inactive after reboot

Question

After Installing RDO (OpenStack Packstack) on CentOS 7.2 (7.2.1511) I always end up with following:

Once OpenStack is successfully installed I can use OpenStack as intended. Even that openstack-status returns:

..
openstack-nova-network:                 inactive  (disabled on boot)
openstack-keystone:                     inactive  (disabled on boot)
mysqld:                                 inactive  (disabled on boot)
.. (and some more)

After a reboot of the system I cannot access Keystone anymore (since it's disabled on boot) but also if I try to start the service manually with:

service openstack-nova-network restart

or all services with

openstack-service start

end in a timeout. So basically - once I've reboot the VM where I installed OpenStack I cannot use OpenStack anymore..

I installed with following commands:

sudo -i
systemctl disable NetworkManager firewalld
systemctl enable network
vi /etc/selinux/config
SELINUX=permissive

sync;reboot

vi /etc/enviroment
LANG=en_US.utf-8
LC_ALL=en_US.utf-8

yum install -y centos-release-openstack-mitaka
yum update -y
yum install -y openstack-packstack
packstack --allinone

Answer 1

I had the some issue with openstack mitaka on centos 7 and this solved the issue: systemctl restart httpd.service

Answer 2

Since those services are disabled, they will not start when rebooted. You first need to enable the service and then start it. Refer to this.

systemctl enable openstack-keystone.service
systemctl start openstack-keystone.service
