2. Create a new Compute database.
The new Havana Compute environment requires a distinct database from the one your
existing Grizzly Compute environment is using. On a system where you have administrative
access to your SQL server, create a new database.
For example, to create a database with the name no va_havana, the MySQL commands
would be:
mysql> create database nova_havana;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on nova_havana.* to nova@ '%';
Query OK, 0 rows affected (0.00 sec)
3. Configure the Compute service:
a. Replace /etc/no va on your Havana Compute controller with the contents of
/etc/no va from your Grizzly controller.
b. In the /etc/no va/no va. co nf file:
Update sq l _co nnecti o n to point to the database created in Step 2. If your old
configuration looked like this:
sql_connection = mysql://nova@ 192.168.122.110/nova
The new configuration should look like this (using the example no va_havana
database):
sql_connection = mysql://nova@ 192.168.122.110/nova_havana
Update the metad ata_ho st setting to point to your new Havana controller.
On your Compute nodes, make sure that the following settings all point to the
address of the local Compute node:
vncserver_pro xycl i ent_ad d ress
