Obsolete:NovaInstall/Cactus
Installing an OpenStack Compute (Nova) Snapshot (Cactus release)
These instructions are for the Cactus release of Nova, 2011.2. If you prefer to run the more recent code rather than the tarball release, refer to NovaInstall.
These instructions do not yet contain all the dependencies, so feel free to edit this page as you sort through the dependencies.
The Cactus release notes contain a list of the features in the Cactus release as well as known issues with the release.
Please ask for assistance in the #openstack IRC channel if you want more information or run into problems.
Single Machine Installation
The instructions are based on Ubuntu commands. For Fedora, RHEL, or CentOS, refer to RHEL6 Nova installation and Nova installation on CentOS.
Step 1: Downloading the Nova compressed file
Download the released package at http://launchpad.net/nova/cactus/2011.2/+download/nova-2011.2.tar.gz.
wget http://launchpad.net/nova/cactus/2011.2/+download/nova-2011.2.tar.gz
Extract the file to the server where you want to install and run Nova.
tar xvzf nova-2011.2.tar.gz
Step 2: Install dependencies
Nova requires rabbitmq for messaging, so install it first.
Note: You must have sudo installed to run these commands as shown here.
sudo apt-get install -y rabbitmq-server sudo apt-get install -y python2.6-dev python-software-properties python-setuptools python-distutils-extra sudo apt-get install libssl-dev sudo apt-get install -y swig m2crypto sudo easy_install pip sudo apt-get install python-pip sudo pip install setuptools
Furthermore, nova-compute will need:
sudo apt-get install -y python-libvirt libvirt-bin
And nova-network will need:
sudo apt-get install vlan curl
Step 3: Build and install Nova services
Switch to the directory where the Python files for Nova are extracted.
cd nova-2011.2
Type or copy/paste in the following line to compile the Python code for OpenStack Compute.
sudo pip install -r tools/pip-requires sudo python setup.py build sudo python setup.py install
When the installation is complete, you'll see the following lines:
Installing nova-volume script to /usr/local/bin Installing nova-debug script to /usr/local/bin Installing nova-import-canonical-imagestore script to /usr/local/bin Installing nova-spoolsentry script to /usr/local/bin Installing nova-objectstore script to /usr/local/bin Installing nova-api script to /usr/local/bin Installing nova-instancemonitor script to /usr/local/bin Installing nova-logspool script to /usr/local/bin Installing nova-scheduler script to /usr/local/bin Installing nova-network script to /usr/local/bin Installing nova-compute script to /usr/local/bin Installing nova-manage script to /usr/local/bin Installing nova-dhcpbridge script to /usr/local/bin Installed /usr/local/lib/python2.6/dist-packages/nova-2011.2-py2.6.egg Processing dependencies for nova==2011.2 Finished processing dependencies for nova==2011.2
Finally, sync the database to pick up any changes:
sudo nova-manage db sync
Next, refer to RunningNova for more information about getting images and starting instances. Be aware that in those steps you might need to do first (or a variation on this):
cd /usr/local/lib/python2.6/dist-packages/nova-2011.2-py2.6.egg/ sudo ln -s /opt/nova-2011.2/CA . sudo ln -s /opt/nova-2011.2/etc .
