Install the Database service This procedure installs the Database module on the controller node. Prerequisites This chapter assumes that you already have a working OpenStack environment with at least the following components installed: Compute, Image Service, Identity. Ubuntu 14.04 Only The Database module is only available under Ubuntu 14.04. Packages are not available for 12.04, or via the Ubuntu Cloud Archive. To install the Database module on the controller: Install required packages: # apt-get install python-trove python-troveclient python-glanceclient \ trove-common trove-api trove-taskmanager # yum install openstack-trove FIXME # zypper install openstack-trove python-troveclient Prepare OpenStack: Source the admin-openrc.sh file. $ source ~/admin-openrc.sh Create a trove user that Compute uses to authenticate with the Identity service. Use the service tenant and give the user the admin role: $ keystone user-create --name=trove --pass=TROVE_PASS --email=trove@example.com $ keystone user-role-add --user=trove --tenant=service --role=admin Edit the the following configuration files, taking the below actions for each file: trove.conf trove-taskmanager.conf trove-conductor.conf Edit the [DEFAULT] section of each file for the, client URLs and logging configuration [DEFAULT] log_dir=/var/log/trove trove_auth_url = http://controller:5000/v2.0 nova_compute_url = http://controller:8774/v2 cinder_url = http://controller:8776/v1 swift_url = http://controller:8080/v1/AUTH_ Set these configuration keys to configure thee Database module to use the Qpid message broker: # openstack-config --set /etc/trove/trove-api.conf \ DEFAULT rpc_backend rabbit # openstack-config --set /etc/trove/trove-taskmaster.conf \ DEFAULT rpc_backend rabbit # openstack-config --set /etc/trove/trove-conductor.conf \ DEFAULT rpc_backend rabbit # openstack-config --set /etc/trove/trove-api.conf DEFAULT qpid_hostname controller # openstack-config --set /etc/trove/trove-taskmaster.conf DEFAULT qpid_hostname controller # openstack-config --set /etc/trove/trove-conductor.conf DEFAULT qpid_hostname controller Configure the Database module to use the RabbitMQ message broker by setting these configuration keys in the [DEFAULT] configuration group of each file: [DEFAULT] ... rpc_backend = rabbit rabbit_host = controller rabbit_password = RABBIT_PASS Set these configuration keys to configure the Database module to use the RabbitMQ message broker: # openstack-config --set /etc/trove/trove-api.conf \ DEFAULT rpc_backend rabbit # openstack-config --set /etc/trove/trove-taskmaster.conf \ DEFAULT rpc_backend rabbit # openstack-config --set /etc/trove/trove-conductor.conf \ DEFAULT rpc_backend rabbit # openstack-config --set /etc/trove/trove-api.conf DEFAULT rabbit_host controller # openstack-config --set /etc/trove/trove-taskmaster.conf DEFAULT rabbit_host controller # openstack-config --set /etc/trove/trove-conductor.conf DEFAULT rabbit_host controller # openstack-config --set /etc/trove/trove-api.conf DEFAULT rabbit_password RABBIT_PASS # openstack-config --set /etc/trove/trove-taskmaster.conf DEFAULT rabbit_password RABBIT_PASS # openstack-config --set /etc/trove/trove-conductor.conf DEFAULT rabbit_password RABBIT_PASS Edit the [keystone_authtoken] section of each file so it matches the listing shown below: [keystone_authtoken] auth_host = controller auth_port = 35357 auth_protocol = http admin_user = trove admin_password = TROVE_PASS admin_tenant_name = service auth_uri = https://controller:5000/v2.0 Edit the [database] section of each file, adding it if necessary, so it matches the listing shown below: [database] connection = mysql://trove:TROVE_DBPASS@controller/trove Edit the trove.conf file so it matches the listing shown below: [DEFAULT] default_datastore = mysql .... # Config option for showing the IP address that nova doles out add_addresses = True network_label_regex = ^NETWORK_LABEL$ .... # ============ notifer queue kombu connection options ======================== notifier_queue_hostname = controller Edit the trove-taskmanager.conf file so it matches the listing shown below: [DEFAULT] .... # Configuration options for talking to nova via the novaclient. # These options are for an admin user in your keystone config. # It proxy's the token received from the user to send to nova via this admin users creds, # basically acting like the client via that proxy token. nova_proxy_admin_user = admin nova_proxy_admin_pass = ADMIN_PASSS nova_proxy_admin_tenant_name = service .... # ============ notifer queue kombu connection options ======================== notifier_queue_hostname = controller ... Create a trove_nolog.conf file: # cp /etc/trove/trove.conf /etc/trove/trove_nolog.conf Edit the trove_nolog.conf file: # remove line starting with logdir and add use_syslog=False Prepare the trove admin database: $ mysql -u root -p mysql> CREATE DATABASE trove; mysql> GRANT ALL PRIVILEGES ON trove.* TO trove@'localhost' IDENTIFIED BY 'TROVE_DBPASS'; mysql> GRANT ALL PRIVILEGES ON trove.* TO trove@'%' IDENTIFIED BY 'TROVE_DBPASS'; Prepare the Database service: Initialize the database: $ trove-manage --config-file=/etc/trove/trove_nolog.conf db_sync Create a datastore. You need to create a separate datastore for each type of database you want to use, for example, MySQL, MongoDB, Cassandra. This example shows you how to create a datastore for a MySQL database: $ trove-manage --config-file=/etc/trove/trove_nolog.conf datastore_update mysql "" Create a trove image. Create an image for the type of database you want to use, for example, MySQL, MongoDB, Cassandra. This image must have the trove guest agent installed, and it must have the trove-guestagent.conf file configured to connect to your OpenStack environment. To correctly configure the trove-guestagent.conf file, do these steps on the guest instance you are using to build your image: Add the following lines to trove-guestagent.conf: rabbit_host = controller rabbit_password = RABBIT_PASS nova_proxy_admin_user = admin nova_proxy_admin_pass = ADMIN_PASSS nova_proxy_admin_tenant_name = service trove_auth_url = http://controller:35357/v2.0 Update the datastore to use the new image, using the trove-manage command. This example shows you how to create a MySQL 5.5 datastore: # trove-manage --config-file=/etc/trove/trove.conf datastore_version_update \ mysql mysql-5.5 mysql glance_image_ID mysql-server-5.5 1 You must register the Database module with the Identity service so that other OpenStack services can locate it. Register the service and specify the endpoint: $ keystone service-create --name=trove --type=database \ --description="OpenStack Database Service" $ keystone endpoint-create \ --service-id=$(keystone service-list | awk '/ trove / {print $2}') \ --publicurl=http://controller:8779/v1.0/%\(tenant_id\)s \ --internalurl=http://controller:8779/v1.0/%\(tenant_id\)s \ --adminurl=http://controller:8779/v1.0/%\(tenant_id\)s Start Database services and configure them to start when the system boots: Restart Database services: # service trove-api restart # service trove-taskmanager restart # service trove-conductor restart # service openstack-trove-api start # service openstack-trove-taskmanager start # service openstack-trove-conductor start # chkconfig openstack-trove-api on # chkconfig openstack-trove-taskmanager on # chkconfig openstack-trove-conductor on
