Installing the Live CD
|
||||
======================
|
||||
|
||||
If you'd like to set up a sandbox installation of Nova, you can use one of these Live CD images.
|
||||
|
||||
If you don't already have VirtualBox installed, you can download it from http://www.virtualbox.org/wiki/Downloads.
|
||||
|
||||
Download the zip or iso file and then follow these steps to try Nova in a virtual environment.
|
||||
|
||||
http://c0047913.cdn1.cloudfiles.rackspacecloud.com/OpenStackNova.x86_64-2010.1.2.iso (OpenSUSE image; root password is "linux" for this image)
|
||||
|
||||
http://c0028699.cdn1.cloudfiles.rackspacecloud.com/nova-vm.zip (~900 MB) (log in information is nova/nova)
|
||||
|
||||
Once a VM is configured and started, here are the basics:
|
||||
|
||||
#. Login to Ubuntu using ID nova and Password nova.
|
||||
|
||||
#. Switch to running as sudo (enter nova when prompted for the password)::
|
||||
|
||||
sudo -s
|
||||
|
||||
#. To run Nova for the first time, enter::
|
||||
|
||||
cd /var/openstack/
|
||||
|
||||
#. Now that you're in the correct directory, enter::
|
||||
|
||||
./nova.sh run
|
||||
|
||||
.. image:: images/novashvirtually.png
|
||||
|
||||
If it's already running, use screen -ls, and when the nova screen is presented,then enter screen -d -r nova.
|
||||
|
||||
These are the steps to get an instance running (the image is already provided in this environment). Enter these commands in the "test" screen.
|
||||
|
||||
::
|
||||
|
||||
euca-add-keypair test > test.pem
|
||||
chmod 600 test.pem
|
||||
euca-run-instances -k test -t m1.tiny ami-tiny
|
||||
euca-describe-instances
|
||||
|
||||
ssh -i test.pem root@10.0.0.3
|
||||
|
||||
To see output from the various workers, switch screen windows with Ctrl+A " (quotation mark).

Nova Quickstart
|
||||
===============
|
||||
|
||||
.. todo::
|
||||
P1 (this is one example of how to use priority syntax)
|
||||
* Document the assumptions about pluggable interfaces (sqlite3 instead of
|
||||
mysql, etc) (todd)
|
||||
* Document env vars that can change things (USE_MYSQL, HOST_IP) (todd)
|
||||
The quickest way to set up an OpenStack development environment for testing is
|
||||
to use `DevStack <http://devstack.org/>`_.
|
||||
|
||||
Recommended System Configuration
|
||||
--------------------------------
|
||||
|
||||
Although Nova can be run on a variety of system architectures, for most users the following will be simplest:
|
||||
|
||||
* Ubuntu Lucid
|
||||
* 10GB Hard Disk Space
|
||||
* 512MB RAM
|
||||
|
||||
For development, Nova can run from within a VM.
|
||||
|
||||
|
||||
Getting the Code
|
||||
----------------
|
||||
|
||||
Nova is hosted on launchpad. You can get the code with the following command
|
||||
|
||||
::
|
||||
|
||||
git clone https://github.com/openstack/nova.git
|
||||
|
||||
The `contrib/nova.sh` file in the source distribution is a script that
|
||||
will quickly set up nova to run on a single machine. It is tested against
|
||||
Ubuntu only, but other distributions are forthcoming.
|
||||
|
||||
A more recent shell script for setting up an OpenStack development environment
|
||||
can be found at http://devstack.org
|
||||
|
||||
Environment Variables
|
||||
---------------------
|
||||
|
||||
By tweaking the environment that nova.sh run in, you can build slightly
|
||||
different configurations (though for more complex setups you should see
|
||||
`Installing and Configuring OpenStack Compute <http://docs.openstack.org/openstack-compute/admin/content/ch03.html>`_).
|
||||
|
||||
* HOST_IP
|
||||
* Default: address of first interface from the ifconfig command
|
||||
* Values: 127.0.0.1, or any other valid address
|
||||
* TEST
|
||||
* Default: 0
|
||||
* Values: 1, run tests after checkout and initial setup
|
||||
* USE_MYSQL
|
||||
* Default: 0, use sqlite3
|
||||
* Values: 1, use mysql instead of sqlite3
|
||||
* MYSQL_PASS (Only useful if $USE_MYSQL=1)
|
||||
* Default: nova
|
||||
* Values: value of root password for mysql
|
||||
* USE_LDAP
|
||||
* Default: 0, use :mod:`nova.auth.dbdriver`
|
||||
* Values: 1, use :mod:`nova.auth.ldapdriver`
|
||||
* LIBVIRT_TYPE
|
||||
* Default: qemu
|
||||
* Values: uml, kvm
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Unless you want to spend a lot of time fiddling with permissions and sudoers,
|
||||
you should probably run nova as root.
|
||||
|
||||
::
|
||||
|
||||
sudo -i
|
||||
|
||||
If you are concerned about security, nova runs just fine inside a virtual
|
||||
machine.
|
||||
|
||||
Use the script to install and run the current trunk. You can also specify a
|
||||
specific branch by putting `lp:~someone/nova/some-branch` after the branch
|
||||
command
|
||||
|
||||
::
|
||||
|
||||
./nova.sh branch
|
||||
./nova.sh install
|
||||
./nova.sh run
|
||||
|
||||
The run command will drop you into a screen session with all of the workers
|
||||
running in different windows You can use eucatools to run commands against the
|
||||
cloud.
|
||||
|
||||
::
|
||||
|
||||
euca-add-keypair test > test.pem
|
||||
euca-run-instances -k test -t m1.tiny ami-tiny
|
||||
euca-describe-instances
|
||||
|
||||
To see output from the various workers, switch screen windows
|
||||
|
||||
::
|
||||
|
||||
<ctrl-a> "
|
||||
|
||||
will give you a list of running windows.
|
||||
|
||||
When the instance is running, you should be able to ssh to it.
|
||||
|
||||
::
|
||||
|
||||
chmod 600 test.pem
|
||||
ssh -i test.pem root@10.0.0.3
|
||||
|
||||
When you exit screen
|
||||
|
||||
::
|
||||
|
||||
<ctrl-a> <ctrl-d>
|
||||
|
||||
nova will terminate. It may take a while for nova to finish cleaning up. If
|
||||
you exit the process before it is done because there were some problems in your
|
||||
build, you may have to clean up the nova processes manually. If you had any
|
||||
instances running, you can attempt to kill them through the api:
|
||||
|
||||
::
|
||||
|
||||
./nova.sh terminate
|
||||
|
||||
Then you can destroy the screen:
|
||||
|
||||
::
|
||||
|
||||
./nova.sh clean
|
||||
|
||||
If things get particularly messed up, you might need to do some more intense
|
||||
cleanup. Be careful, the following command will manually destroy all runnning
|
||||
virsh instances and attempt to delete all vlans and bridges.
|
||||
|
||||
::
|
||||
|
||||
./nova.sh scrub
|
||||
|
||||
You can edit files in the install directory or do a git pull to pick up new versions. You only need to do
|
||||
|
||||
::
|
||||
|
||||
./nova.sh run
|
||||
|
||||
to run nova after the first install. The database should be cleaned up on each run.
|
||||
To start over, drop the nova, glance, and keystone databases, delete the logs,
|
||||
delete the IP addresses and bridges created, and then recreate the databases
|
||||
and restart the services to get back to a clean state.

Getting Started with Nova
|
||||
=========================
|
||||
|
||||
This code base is continually changing, so dependencies also change. If you
|
||||
encounter any problems, see the :doc:`../community` page.
|
||||
The `contrib/nova.sh` script should be kept up to date, and may be a good
|
||||
resource to review when debugging.
|
||||
|
||||
The purpose of this document is to get a system installed that you can use to
|
||||
test your setup assumptions. Working from this base installtion you can
|
||||
tweak configurations and work with different flags to monitor interaction with
|
||||
your hardware, network, and other factors that will allow you to determine
|
||||
suitability for your deployment. After following this setup method, you should
|
||||
be able to experiment with different managers, drivers, and flags to get the
|
||||
best performance.
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
|
||||
Related servers we rely on
|
||||
|
||||
* **RabbitMQ**: messaging queue, used for all communication between components
|
||||
|
||||
Optional servers
|
||||
|
||||
* **OpenLDAP**: By default, the auth server uses the RDBMS-backed datastore by
|
||||
setting FLAGS.auth_driver to `nova.auth.dbdriver.DbDriver`. But OpenLDAP
|
||||
(or LDAP) could be configured by specifying `nova.auth.ldapdriver.LdapDriver`.
|
||||
There is a script in the sources (`nova/auth/slap.sh`) to install a very basic
|
||||
openldap server on ubuntu.
|
||||
* **ReDIS**: There is a fake ldap auth driver
|
||||
`nova.auth.ldapdriver.FakeLdapDriver` that backends to redis. This was
|
||||
created for testing ldap implementation on systems that don't have an easy
|
||||
means to install ldap.
|
||||
* **MySQL**: Either MySQL or another database supported by sqlalchemy needs to
|
||||
be avilable. Currently, only sqlite3 an mysql have been tested.
|
||||
|
||||
Python libraries that we use (from pip-requires):
|
||||
|
||||
.. literalinclude:: ../../../tools/pip-requires
|
||||
|
||||
Other libraries:
|
||||
|
||||
* **XenAPI**: Needed only for Xen Cloud Platform or XenServer support. Available
|
||||
from http://wiki.xensource.com/xenwiki/XCP_SDK or
|
||||
http://community.citrix.com/cdn/xs/sdks.
|
||||
|
||||
External unix tools that are required:
|
||||
|
||||
* iptables
|
||||
* ebtables
|
||||
* gawk
|
||||
* curl
|
||||
* kvm
|
||||
* libvirt
|
||||
* dnsmasq
|
||||
* vlan
|
||||
* open-iscsi and iscsitarget (if you use iscsi volumes)
|
||||
|
||||
Nova uses cutting-edge versions of many packages. There are ubuntu packages in
|
||||
the nova-core trunk ppa. You can use add this ppa to your sources list on an
|
||||
ubuntu machine with the following commands::
|
||||
|
||||
sudo apt-get install -y python-software-properties
|
||||
sudo add-apt-repository ppa:nova-core/trunk
|
||||
|
||||
Recommended
|
||||
-----------
|
||||
|
||||
* euca2ools: python implementation of aws ec2-tools and ami tools
|
||||
* build tornado to use C module for evented section
|
||||
|
||||
|
||||
Installation
|
||||
--------------
|
||||
|
||||
You can install from packages for your particular Linux distribution if they are
|
||||
available. Otherwise you can install from source by checking out the source
|
||||
files from the `Nova Source Code Repository <http://code.launchpad.net/nova>`_
|
||||
and running::
|
||||
|
||||
python setup.py install
|
||||
|
||||
Configuration
|
||||
---------------
|
||||
|
||||
Configuring the host system
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Nova can be configured in many different ways. In this "Getting Started with Nova" document, we only provide what you need to get started as quickly as possible. For a more detailed description of system
|
||||
configuration, start reading through `Installing and Configuring OpenStack Compute <http://docs.openstack.org/openstack-compute/admin/content/ch03.html>`_.
|
||||
|
||||
`Detailed instructions for creating a volume group are available <http://docs.openstack.org/openstack-compute/admin/content/ch05s07.html>`_, or use these quick instructions.
|
||||
|
||||
* Create a volume group (you can use an actual disk for the volume group as
|
||||
well)::
|
||||
|
||||
# This creates a 1GB file to create volumes out of
|
||||
dd if=/dev/zero of=MY_FILE_PATH bs=100M count=10
|
||||
losetup --show -f MY_FILE_PATH
|
||||
# replace /dev/loop0 below with whatever losetup returns
|
||||
# nova-volumes is the default for the --volume_group flag
|
||||
vgcreate nova-volumes /dev/loop0
|
||||
|
||||
|
||||
Configuring Nova
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
Configuration of the entire system is performed through python-gflags. The
|
||||
best way to track configuration is through the use of a flagfile.
|
||||
|
||||
A flagfile is specified with the ``--flagfile=FILEPATH`` argument to the binary
|
||||
when you launch it. Flagfiles for nova are typically stored in
|
||||
``/etc/nova/nova.conf``, and flags specific to a certain program are stored in
|
||||
``/etc/nova/nova-COMMAND.conf``. Each configuration file can include another
|
||||
flagfile, so typically a file like ``nova-manage.conf`` would have as its first
|
||||
line ``--flagfile=/etc/nova/nova.conf`` to load the common flags before
|
||||
specifying overrides or additional options.
|
||||
|
||||
To get a current comprehensive list of flag file options, run bin/nova-<servicename> --help, or refer to a static list at `Reference for Flags in nova.conf <http://docs.openstack.org/openstack-compute/admin/content/ch05s08.html>`_.
|
||||
|
||||
A sample configuration to test the system follows::
|
||||
|
||||
--verbose
|
||||
--nodaemon
|
||||
--auth_driver=nova.auth.dbdriver.DbDriver
|
||||
|
||||
Running
|
||||
-------
|
||||
|
||||
There are many parts to the nova system, each with a specific function. They
|
||||
are built to be highly-available, so there are may configurations they can be
|
||||
run in (ie: on many machines, many listeners per machine, etc). This part
|
||||
of the guide only gets you started quickly, to learn about HA options, see
|
||||
`Installing and Configuring OpenStack Compute <http://docs.openstack.org/openstack-compute/admin/content/ch03.html>`_.
|
||||
|
||||
Launch supporting services
|
||||
|
||||
* rabbitmq
|
||||
* redis (optional)
|
||||
* mysql (optional)
|
||||
* openldap (optional)
|
||||
|
||||
Launch nova components, each should have ``--flagfile=/etc/nova/nova.conf``
|
||||
|
||||
* nova-api
|
||||
* nova-compute
|
||||
* nova-objectstore
|
||||
* nova-volume
|
||||
* nova-scheduler

Running the Cloud

-----------------
|
||||
|
||||
The fastest way to get a test cloud running is by following the directions in the :doc:`../quickstart`. It relies on a nova.sh script to run on a single machine.

The fastest way to get a test cloud running is by following the directions in the :doc:`../quickstart`.
|
||||
|
||||
Nova's cloud works via the interaction of a series of daemon processes that reside persistently on the host machine(s). Fortunately, the :doc:`../quickstart` process launches sample versions of all these daemons for you. Once you are familiar with basic Nova usage, you can learn more about daemons by reading :doc:`../service.architecture` and :doc:`binaries`.
