Distributions release OpenStack packages as part of the distribution or using other methods because of differing release schedules. Perform these procedures on all nodes. Disable or remove any automatic update services because they can impact your OpenStack environment. Install the Ubuntu Cloud archive keyring and repository: # apt-get install ubuntu-cloud-keyring # echo "deb http://ubuntu-cloud.archive.canonical.com/ubuntu" \ "trusty-updates/juno main" > /etc/apt/sources.list.d/cloudarchive-juno.list Install the yum-plugin-priorities package to enable assignment of relative priorities within repositories: # yum install yum-plugin-priorities On RHEL and CentOS, enable the EPEL repository: # yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm Fedora does not require this repository. On RHEL, enable the extras repository using the subscription manager: # subscription-manager repos --enable=rhel-7-server-extras-rpms CentOS and Fedora do not require this repository. Install the rdo-release-juno package to enable the RDO repository: # yum install http://rdo.fedorapeople.org/openstack-juno/rdo-release-juno.rpm Enable the Open Build Service repositories based on your openSUSE or SLES version: On openSUSE 13.1: # zypper addrepo -f obs://Cloud:OpenStack:Juno/openSUSE_13.1 Juno On SLES 11 SP3: # zypper addrepo -f obs://Cloud:OpenStack:Juno/SLE_11_SP3 Juno The packages are signed by GPG key 893A90DAD85F9316. You should verify the fingerprint of the imported GPG key before using it. Key ID: 893A90DAD85F9316 Key Name: Cloud:OpenStack OBS Project <Cloud:OpenStack@build.opensuse.org> Key Fingerprint: 35B34E18ABC1076D66D5A86B893A90DAD85F9316 Key Created: Tue Oct 8 13:34:21 2013 Key Expires: Thu Dec 17 13:34:21 2015 The Juno release is available only in Debian Experimental (otherwise called rc-buggy), as Jessie is frozen soon, and will contain Icehouse. However, the Debian maintainers of OpenStack also maintain a non-official Debian repository for OpenStack containing Wheezy backports. On all nodes, install the Debian Wheezy backport repository Juno: # echo "deb http://archive.gplhost.com/debian juno-backports main" >>/etc/apt/sources.list Install the Debian Wheezy OpenStack repository for Juno: # echo "deb http://archive.gplhost.com/debian juno main" >>/etc/apt/sources.list Update the repository database and install the key: # apt-get update && apt-get install gplhost-archive-keyring Update the package database, upgrade your system, and reboot for all changes to take effect: # apt-get update && apt-get dist-upgrade # reboot Numerous archive.gplhost.com mirrors are available around the world. All are available with both FTP and HTTP protocols (you should use the closest mirror). The list of mirrors is available at http://archive.gplhost.com/readme.mirrors. The Debian OpenStack packages are maintained on Debian Sid (also known as Debian Unstable) - the current development version. Backported packages run correctly on Debian Wheezy with one caveat: All OpenStack packages are written in Python. All packages support version 2.7; porting to Python version 3 is ongoing. Note that Debian Wheezy uses Python 2.6 and 2.7, with Python 2.7 as the default interpreter; Sid has only Python 2.7. There is one packaging change between these two. In Python 2.6, you installed the python-argparse package separately. In Python 2.7, this package is installed by default. Unfortunately, in Python 2.7, this package does not include Provides: python-argparse directive. Because the packages are maintained in Sid where the Provides: python-argparse directive causes an error, and the Debian OpenStack maintainer wants to maintain one version of the OpenStack packages, you must manually install the python-argparse on each OpenStack system that runs Debian Wheezy before you install the other OpenStack packages. Use the following command to install the package: # apt-get install python-argparse This caveat applies to most OpenStack packages in Wheezy. Upgrade the packages on your system: # apt-get update && apt-get dist-upgrade # yum upgrade # zypper refresh && zypper dist-upgrade If the upgrade process includes a new kernel, reboot your system to activate it. RHEL and CentOS enable SELinux by default. Install the openstack-selinux package to automatically manage security policies for OpenStack services: # yum install openstack-selinux Fedora does not require this package. The installation process for this package can take a while.
