Use the Packstack “allinone” option to deploy an Openstack-in-a-box. This tends to work better than trying to get DevStack to work on CentOS.

  1. First, create a CentOS 7 VM. Make sure to use a flavor with enough memory. If you will only be running PackStack, m1.large will work. If you want to deploy other services in the same VM, use m1.xlarge.

IMPORTANT: The steps below should be done INSIDE THE VM, NOT directly on your computer
Installing PackStack on your computer will probably make it stop working.

  1. In the VM, add this line to the file /etc/resolv.conf:
    options single-request

    And add this line to /etc/sysconfig/network:
    RES_OPTIONS=single-request

  2. Follow these instructions to install and deploy PackStack
    Note: the MOC Kaizen Openstack cluster is currently running OpenStack Mitaka, but if you want a different version, you can replace ‘mitaka’ in the first command below with that release

    $ sudo yum install -y centos-release-openstack-mitaka $ sudo yum update -y $ sudo yum install -y openstack-packstack $ sudo packstack –allinone

    The last command takes a long time so just let it run. When it is finished, you should see a message like this:

**** Installation completed successfully ******

Additional information:
 * A new answerfile was created in: /root/packstack-answers-20170601-190213.txt
 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
 * File /root/keystonerc_admin has been created on OpenStack client host 10.11.12.13. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://10.11.12.13/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
 * The installation log file is available at: /var/tmp/packstack/20170601-190212-ESb_Vc/openstack-setup.log
 * The generated manifests are available at: /var/tmp/packstack/20170601-190212-ESb_Vc/manifests
  1. Get the admin credentials for your OpenStack cluster from the file /root/keystonerc_admin. Test that your dashboard is working by navigating to http://<floating-IP-of-your-instance>/dashboard and logging in.

If your instance does not have a floating IP, but another instance on the same private network does, you can use this command to forward a port on your local machine:

ssh -L 8080:10.11.12.13 <user>@<host-with-floating-ip>

where <user> and <host-with-floating-ip> point to the host which has a public IP. After the ssh connection is live, you can point your browser to localhost:8080/dashboard and the login page should appear.
