Re: Problems connecting Dashboard and Nova

 

Yeah

It's trying to clear an existing database named nova in mysql.. try the following before install and run:

mysql -u root -p <root_password> -e"create database nova"

This should create an empty database called nova for it to whack.

Thanks

Arvind,

I ran the script with USE_MYSQL=1, also inverted the order of lines 321 & 322 in the nova.sh script (was generating an error). Didn't complete due to the following db-related error:

"Command failed, please check log for more info
2011-08-09 14:58:47,555 CRITICAL nova [-] (OperationalError) (1049, "Unknown database 'nova'") None None ...."

Any ideas what could be the problem?

Thanks for your help,

Mauricio

    Mauricio,

    The cloudbuilders script starts the server on port 80
    automatically. Afaik it also runs the sampledata script from
    keystone to set up a couple of users. You might try user:'joeuser'
    pass: 'secrete' or user:'joeadmin' pass:'secrete' .. both accounts
    are autocreated from the sample data script.

    As to your sql problem.. I ran into the same when using sqlite
    with the cloudbuilders image. Try this, install mysql and:

    export USE_MYSQL=1
    export MYSQL_PASS=<your mysql root password>

    then
    // Clear our existing install data
    nova.sh terminate
    nova.sh clean
    nova.sh scrub
    nova.sh install
    nova.sh run

    The nova processes are run in a SCREEN command. The script does
    not install euca2ools so you'll need to install those separately.

    Thanks
    Arvind

    I didn't see any of the nova processes running with 'nova-*'
    names. What names do they have?

    I wasn't able to run either the nova-manage nor the euca tools.
    How can I do this? It is very helpful to have both access to the
    command line tools in nova as well as the Dashboard.

    Thanks,

        $ sudo ./nova.sh branch

        This starts up everything in a screen session.  When you
        detach the screen with Ctrl-A, D all of the openstack
        components will shut down.

        The nova.sh script generally sets up a clean environment
        every time it is run.  This makes it mostly useful for demo
        and test environments.

        Hopefully this helps.

            Thanks Mark,

            I'm trying your nova.sh script. I run it in a clean
            Ubuntu instance as 'nova.sh install'. However it didn't
            start the nova processes.

            Please let me know what is the correct way of runnig the
            scrpt to get everything running.

                Have you set up and configured a keystone instance
                for authentication?  The dashboard only supports
                Keystone based authentication right now, and it looks
                like you're trying to connect to nova using Nova's
                builtin auth.  That howto you are following is quite
                old.   If you're looking to get openstack up and
                running on a single box, you might want to try this
                script
                (https://github.com/4P/deployscripts/blob/master/nova.sh)
                which sets up nova+keystone+glance+dashboard on a
                single host.

                 If you'd like to modify your existing setup, take a
                look at https://github.com/openstack/keystone, which
                talks about how to set up keystone and integrate it
                into your nova installation.

                    Hi,

                    I installed Nova and Dashboard on a single
                    VirtualBox Ubuntu guest, following the
                    instructions in:
                    http://uksysadmin.wordpress.com/2011/02/17/running-openstack-under-virtualbox-a-complete-guide/
                    and
                    http://wiki.openstack.org/OpenStackDashboard

                    I added the following lines in Dahsboard's
                     local_settings.py, based on information
                    extracted from the novarc file in Nova:

                    NOVA_CERT="/home/mauricio/ostack/cloud/creds/cacert.pem"
                    ]

                    The nova install, runs well, tested it using euca
                    tools.

                    The GUI part of Dashboard works but fails
                    connecting to Nova, generating the this error on
