Some very rough notes on installing and configuring OpenNebula on an Ubuntu host.
On the Server host:
apt-get install opennebula
Adding system user `oneadmin’ (UID nnn) …
Adding new user `oneadmin’ (UID nnn) with group `nogroup’ …
The home directory `/var/lib/one’ already exists. Not copying from `/etc/skel’.
adduser: Warning: The home directory `/var/lib/one’ does not belong to the user you are currently creating.
Generating public/private rsa key pair.
Your identification has been saved in /var/lib/one/.ssh/id_rsa.
Your public key has been saved in /var/lib/one/.ssh/id_rsa.pub.
The key fingerprint is:
The key’s randomart image is:
+–[ RSA 2048]—-+
| . o.. |
(more random artwork)
test the installation by running the new “onehost” command:
onehost [<options>] <command> [<parameters>]
-l, –list x,y,z Selects columns to display with list
–list-columns Information about the columns available
to display, order or filter
-o, –order x,y,z Order by these columns, column starting
with – means decreasing order
-f, –filter x,y,z Filter data. An array is specified
with column=value pairs.
-d, –delay seconds Sets the delay in seconds for top
-v, –verbose Tells more information if the command
-h, –help Shows this help message
–version Shows version and copyright information
* create (Adds a new machine to the pool)
onehost create <hostname> <im_mad> <vmm_mad> <tm_mad>
* show (Gets info from a host)
onehost show <host_id>
* delete (Removes a machine from the pool)
onehost delete <host_id>
* list (Lists machines in the pool)
* enable (Enables host)
onehost enable <host_id>
* disable (Disables host)
onehost disable <host_id>
* top (Lists hosts continuously)
So far so simple, so it’s time to set up a new host and install the client…
This is done by installing the node package like so:
sudo apt-get install opennebula-node
then starting defining and adding the node to the Master instance via the onehost command.
After that’s done, you can move on to set up a private network for your cloud, create you own KVM images, and start firing up VM’s in your own personal cloud.
More detail coming soon…
