    Hello! i have one error.. :-( i don’t solve this problem. (Same procedure)

    ERROR : Error appeared during Puppet run:
    Error: Could not prefetch keystone_service provider ‘openstack’: Command: ‘openstack [“service”, “list”, “–quiet”, “–format”, “csv”, “–long”]’ has been running for more then 20 seconds!

    How can you suggest setting SSH config option ‘PermitRootLogin’ to ‘yes’ and disable SELinux when this article ‘’ clearly state that this is NOT a good idea, if you want a stable and secure server?

    It would be nice if this tutorial was edited so that installation of OpenStack could be done on a secure server :)

    Thanks :)

  4. Evans Banda says:

    I got stuck on the “yum install openstack-packstack” part. No package openstack-packstack available.

  5. cmdrtech says:

    Just a quick question. Shouldnt the # packstack –gen-answer-file=’date +”%d.%m.%y”‘.conf
    actually have backticks to make the com,and produce the date.conf file? Maybe its just a text translation thing.

    Here is what i mean
    # packstack –gen-answer-file=`date +”%d.%m.%y”`.conf

    • matei cezar says:

      Yes…it must have backtricks to produce the command output. You can also use command substitution with $(command to execute)

    • Matei Cezar says:

      I see that your Linux knowledge is limited. No offence but you should first start to learn how the system and Linux bash operates and then go to more complicated stages, such as Openstack, which is very hard to be configured for beginners.

  6. Matei Cezar says:

    It seems to be a bug or a compatibility problem with already installed software or libraries on your system. Please consult OpenStack forums for this issue or send the output of the log file to their mail list.
