Installing the MAAS Server Operating System Canonical 5 of 32 v1.6

5 Note: We assume in this example that the MAAS server has a dedicated NIC to manage the IPMI cards of the nodes. Please update accordingly for every customer 1. Boot the server and install via USB or CD 2. Choose Install Ubuntu Server 3. Configure the network manually IP: Net Mask: Gateway: DNS: Hostname: maas Domain Name: customer.com After that we add the IPMI network to eth1: Edit /etc/network/interfaces and add eth1: auto eth1 iface eth1 inet static address netmask Section Status Comments Installing the MAAS Server Operating System PENDING DONE If there are issues or comments worth pointing out include them here, if not leave it blank. Installing and Configuring the MAAS Service Install MAAS: Login by ssh to the MAAS server. $ sudo apt-get update $ sudo apt-get install -y maas maas-dhcp maas-dns maas-cli ntp After this we can log into MAAS at Create a superuser account Which you will use to log into the MAAS web interface. We will use root as username and ubuntu as password Canonical 6 of 32 v1.6

6 $ sudo maas createsuperuser Import the isos from the Canonical archive: Specify the images to download We are going to use only Ubuntu LTS (Precise). Edit /etc/maas/import_pxe_files and change the RELEASES line so it looks like: RELEASES="precise" Save the file and exit Download the images $ sudo maas-import-pxe-files Configure the rest with the Web UI Add the ssh public key: Log into the MAAS web interface and add a ssh public key under your user preferences. This key will be added to the.ssh/authorized_keys of the ubuntu user for machines deployed via MAAS. Configure the DHCP service: Click on the settings icon next to the search box in the MAAS main screen. Scroll down and under Default domain for new nodes enter customer.com. Then scroll back up and on Cluster controllers click the edit icon. Under DNS zone name enter customer.com Click on the edit icon of the NIC that will be used for DHCP. Under Management select Manage DHCP and DNS Under Interfaces click on the edit button for the interface that will make the DHCP offers to the MAAS nodes and enter these settings: IP: Subnet mask: Broadcast IP: Router IP: IP range low: IP range high: Configure squid-deb-proxy Squid-deb-proxy will cache the deb packages downloaded by the MAAS nodes from Canonical 7 of 32 v1.6

Enlisting and Commissioning Machines Power on all the remaining machines. Note: The machines must be set to PXE boot. They will automatically PXE boot from the MAAS server, enlist then power off. Once machines are enlisted they will appear in the MAAS Web UI as Declared. Edit each machine changing its hostname to the desired one in MAAS, for example, nova-compute-01.customer.com, then click to Accept and Commission each machine. Note: to accept all the nodes from the MAAS command line interface we would do the following: 1. Log into MAAS from the MAAS server: Canonical 8 of 32 v1.6

8 $ maas-cli login root 2. Enter the API Key found in the MAAS Web UI under root and then Preferences. 3. Accept all the nodes: $ maas-cli root nodes accept-all MAAS will power on and commission the accepted machines. Once commissioned, the machines will show as being in the Ready state in the MAAS Web UI and will be powered off by MAAS. Section Status Comments Enlisting and Commissioning Machines PENDING DONE If there are issues or comments worth pointing out include them here, if not leave it blank. Setting up the Juju Bootstrap Node Change DNS name of the node that will be the bootstrap node In the MAAS Web UI, change the name of the machine intended to be the bootstrap node to zookeeper.customer.com. Also change the names of all other machines for their intended role, e.g: nova-compute-01.customer.com, nova-compute-02.customer.com, and so on. Create the Juju client environment for MAAS The Juju client can be installed on any machine and for convenience we will use the MAAS server: Login by ssh to the maas server. Install the Juju repository ppa:juju/pkgs: $ sudo apt-get install -y python-software-properties $ sudo apt-add-repository ppa:juju/pkgs $ sudo apt-get update $ sudo apt-get install -y juju juju-jitsu charm-tools bzr Edit ~/.juju/environments.yaml on the MAAS node adding the following with the correct oauth API key found in the MAAS Web UI under the user preferences. environments: mymaas: Canonical 9 of 32 v1.6

We need to have that ssh key in the node we run juju bootstrap from Now run juju bootstrap which will power on zookeeper.customer.com as the bootstrap node: $ juju bootstrap --constraints maas-name=zookeeper.customer.com Note: if we don t need or want to specify which node the zookeeper needs to be installed on, then we can ignore the --constraints option above. This will take a few minutes to complete. Note: after bootstrapping the node we will see in the MAAS Web UI the node as Allocated to root. We can check the progress in the rsyslog file in MAAS for that node: if, for example, its IP is , then we would do this: $ sudo tail -f /var/log/maas/rsyslog/ customer.com/2013/02/21/messages As the installation completes check the status: $ juju status At this point, the bootstrap/zookeeper node should show as running. Now clear the created constraint for maas-name: $ juju set-constraints maas-name= Make sure that the constraint set is cleared: $ juju get-constraints Note: More information about juju constraints available here: Canonical 10 of 32 v1.6

10 We want the ppa version of Juju in the Juju node so we proceed as we did before for the Juju node: $ juju ssh 0 $ sudo apt-add-repository ppa:juju/pkgs $ sudo apt-get update $ sudo apt-get install juju Note: Alternatively we can just include the following line in the file.juju/environments.yaml juju-origin: ppa Section Status Comments Setting up the Juju Bootstrap Node PENDING DONE If there are issues or comments worth pointing out include them here, if not leave it blank. Verify all the nodes by installing a clean Ubuntu image We need to download the Ubuntu charm to deploy it to all the hosts. We can do this from the MAAS node: $ sudo apt-get install charm-tools $ mkdir -p $HOME/charms/precise $ cd $HOME/charms/precise $ charm get ubuntu Note: we can specify with -n the total number of nodes we will be deploying the Ubuntu Charm to. Then we deploy the Ubuntu charm to all the nodes. $ juju deploy -n 18 ubuntu After verifying that the installation of Ubuntu on the nodes went well, we destroy the service ubuntu that we just deployed: $ juju destroy-service ubuntu Canonical 11 of 32 v1.6

Install NTP on each machine In order to ensure that all machines are in sync, install the ntp package on each machine. $ for machine in `juju status grep machine grep -v machines awk '{ print $2 }'`; do juju ssh $machine "sudo apt-get -y install ntp" done Section Status Comments Install NTP on each machine PENDING DONE If there are issues or comments worth pointing out include them here, if not leave it blank. Deploy OpenStack All new machines should show as Ready in the MAAS Web UI and the bootstrap node should be running, we can begin deploying the OpenStack charms. Define where the services will be allocated Note: The table at the beginning of this document shows the decided roles as well, this is a reminder before we start deploying roles/services to nodes. We will use the following setup: Juju Bootstrap node Main service: zookeeper Other services allocated: Nova Cloud Controller Main service: Nova Cloud Controller Other services allocated: Keystone, OpenStack Dashboard (Horizon) Canonical 12 of 32 v1.6

14 Comments If there are issues or comments worth pointing out include them here, if not leave it blank. Deploy the OpenStack Services Note: juju deploy deploys the service to a MAAS node and juju add-unit scales out the deployed service to additional nodes. By using constraints we can decide what node we deploy to or scale out to. Note: to watch the output of juju running hooks on each node, open an additional terminal on the maas server and run: $ juju debug-log Note: The OpenStack related services need the openstack.yaml files when we deploy them. Deploy Swift services to swift storage nodes We can start by deploying Swift Storage on every node allocated to Swift Storage. From the directory where we have the openstack.yaml file and the charms directory we run the following commands: $ juju deploy --repository. --config=openstack.yaml --constraints maas-name=swift-storage-01.customer.com local:precise/swift-storage $ juju set-constraints maas-name=swift-storage-02.customer.com $ juju add-unit swift-storage $ juju set-constraints maas-name=swift-storage-03.customer.com $ juju add-unit swift-storage $ juju set-constraints maas-name=swift-storage-04.customer.com $ juju add-unit swift-storage $ juju set-constraints maas-name=swift-storage-05.customer.com $ juju add-unit swift-storage Clear the constraints: $ juju set-constraints maas-name= Make sure that we don t overwrite sdc in future deployments: $ juju set swift-storage overwrite=false Deploy swift-proxy (Swift API) $ juju deploy --repository. --config=openstack.yaml --constraints Canonical 15 of 32 v1.6

With juju status we check the identification number assigned to each node and we will use it to deploy services to the desired nodes. If the output of juju status contains this: 17: agent-state: running dns-name: nova-cloud-controller-01.customer.com7ba9-11e2-88c fd7032/ instance-id: /MAAS/api/1.0/nodes/node-6de875ee-7ba9-11e2-88c fd7032/ instance-state: unknown In this case we will use the node ID 17 to deploy to nova-cloud-controller-01.customer.com the desired services. One at a time, waiting for each to finish. Note: if the services below have a dedicated machine we will use juju deploy as in the above services, instead jitsu deploy-to Deploy Glance $ jitsu deploy-to <machine-id> --repository. --config=openstack.yaml local:precise/glance Deploy Cinder $ jitsu deploy-to <machine-id> --repository. --config=openstack.yaml local:precise/cinder Deploy MySQL $ jitsu deploy-to <machine-id> --repository. local:precise/mysql Deploy RabbitMQ Server $ jitsu deploy-to <machine-id> --repository. local:precise/rabbitmq-server Deploy Nova Compute $ jitsu deploy-to <machine-id> --repository. --config=openstack.yaml local:precise/nova-compute Deploy Keystone Canonical 16 of 32 v1.6

Add relations between the OpenStack services Check juju status Verify that the proper machines are deployed and that there are no errors reported: $ juju status Note: It is recommended to verify that each relation is added successfully using juju status before moving to the next relation. Some relations may involve the same node, such as mysql, and may conflict if configuration is happening on the same node at the same time. Note: It is a good practice to check the juju log during the creation of the relations: $ juju debug-log Start adding relations between charms: $ juju add-relation keystone mysql We wait until the relation is set. After it finishes check it with juju status: $ juju status mysql $ juju status keystone If the relations are set and the services started then we proceed with the rest. $ juju add-relation nova-cloud-controller mysql $ juju add-relation nova-cloud-controller rabbitmq-server $ juju add-relation nova-cloud-controller glance $ juju add-relation nova-cloud-controller keystone $ juju add-relation nova-compute mysql Canonical 17 of 32 v1.6

Set up Access to Openstack and Start Booting VMs Once charms are deployed and relations are added, we can configure the private network on each compute node. Get the Keystone IP Address and admin_token Get the admin token from the machine running the keystone service: $ juju ssh keystone/0 $ sudo grep admin_token /etc/keystone/keystone.conf Save the admin_token to use it on the next step. Create an rc file with the OpenStack environment We create a nova.rc file that will have the required environment to run OpenStack commands (mainly nova). First find the Keystone hostname To find the Keystone hostname we can run juju status keystone: $ juju status keystone grep dns-name :27:54,355 INFO Connecting to environment :27:55,038 INFO Connected to environment.

Download the Ubuntu Cloud Image $ mkdir ~/iso $ cd ~/iso $ wget k1.img Import the Ubuntu Cloud Image into Glance Note: glance comes with the package glance-client which may need to be installed where you plan the run the command from $ apt-get install gla nce-client $ glance add name="precise x86_64" is_public=true container_format=ovf disk_format=qcow2 < precise-server-cloudimg-amd64-disk1.img Create OpenStack private network Note: nova-manage can be run from the nova-cloud-controller node or any of the nova-compute nodes. To access the node we run the following command: $ juju ssh nova-cloud-controller/0 Note: If the flat-interface (physical interface used by the bridge connecting the VMs) in the compute nodes is not up, for instance if only eth0 is configured, then the interface needs to be up before we can boot instances. This will be needed in the compute nodes in /etc/network/interfaces and ifup eth1 after adding these lines: Canonical 19 of 32 v1.6

19 auto eth1 iface eth1 inet manual up ifconfig eth1 up $ sudo nova-manage network create --label=private --fixed_range_v4= /27 --num_networks=1 --network_size=32 --multi_host=t --bridge_interface=eth0 --bridge=br100 To make sure that we have created the network we can now run the following command: $ sudo nova-manage network list Create OpenStack public / floating network $ sudo nova-manage floating create --ip_range= /26 $ sudo nova-manage floating list Allow ping and ssh access adding them to the default security group Note: The following commands are run from a machine where we have the package python-novaclient installed and within a session where we have loaded the above created nova.rc file. $ nova secgroup-add-rule default icmp /0 $ nova secgroup-add-rule default tcp /0 Create and register the ssh keys in OpenStack Generate a default keypair This is done in the system we use as the OpenStack nova client. We name the private key file admin-key. Make sure the file doesn t exist before creating it. $ ssh-keygen -t rsa -f ~/.ssh/admin-key Copy the public key into the Nova Cloud Controller We will name it admin-key: Note: In the precise version of python-novaclient the command works with --pub_key instead of --pub-key $ nova keypair-add --pub-key ~/.ssh/admin-key.pub admin-key And make sure it s been successfully created: $ nova keypair-list Create our first instance We created an image with glance before. Now we need the image ID to start our first Canonical 20 of 32 v1.6

First registering manually the MAAS and Juju nodes to Landscape 2. Then using the landscape-client charm to register subsequent Juju deployed nodes. Note: We will need the Landscape credentials (account name and password) to proceed with the registration of the nodes. Register the MAAS and Juju nodes to Landscape For the MAAS node and the Juju node, the registration is manually done.

Enable VNC access to the OpenStack Instances By default, the Ubuntu Cloud charms don t enable VNC access to the OpenStack instances. To enable it, we need to manually install the required packages and configure the Nova Compute nodes and the VNC proxy. Set up the OpenStack VNC Proxy We need to decide what node will be our VNC Proxy. Let s use the Nova Cloud Controller for this setup: Check with juju status the service unit for nova cloud controller and ssh to it with juju: $ juju ssh nova-cloud-controller/0 Canonical 23 of 32 v1.6

We detected that in old IPMI versions (1.29) some privileges for the user that MAAS creates are not set by default. Check the IPMI configuration: $ bmc-config -h u ADMIN -p ADMIN --checkout Ensure that Lan_Enable_IPMI_Msgs is set to Yes and Lan_Privilege_Limit is set to Administrator for the user that MAAS uses (Username maas or maas-enlist or maas-commission) Set them accordingly to the right user (in the example User3): $ bmc-config -h u ADMIN -p ADMIN --commit --key-pair="user3:lan_privilege_limit=administrator" Force a node to PXE boot with IPMI $ cat ipmi-config-reboot Section Chassis_Power_Conf Power_Restore_Policy EndSection Section Chassis_Boot_Flags Boot_Flags_Persistent Boot_Device EndSection No PXE Off_State_AC_Apply $ ipmi-chassis-config -h u ADMIN -p ADMIN --commit --filename ipmi-config-reboot $ ipmipower -h u ADMIN -p ADMIN --cycle --on-if-off : ok PXE boot all the nodes at once $ cat ipmi_list.txt Canonical 26 of 32 v1.6

27 If Juju doesn t work as expected, for instance juju ssh 0 not logging in, we can restart the Juju services from the zookeeper node this way: $ sudo restart juju-provision-agent $ sudo restart juju-machine-agent Increase the Client Connections for Zookeeper By default Zookeeper has a limit of 10 simultaneous client connections and this can lead to issues with Juju when we install a number of charms on the same node. Adding this line to /etc/zookeeper/conf/zoo.cfg will fix it: maxclientcnxns=30 References MAAS MaaS Website MaaS Documentation Setup the MaaS server Juju Juju documentation Install Juju Setup Juju nments-yaml Juju FAQ Juju webcast Juju demo Canonical 28 of 32 v1.6
