Welcome to Nutanix Community EditionNutanix Community Edition is a free version of Nutanix AOS, which powers the Nutanix enterprise cloudplatform. The Community Edition of AOS is designed for people interested in test driving its main featureson their own test hardware and infrastructure. As stated in the end user license agreement, CommunityEdition is intended for internal business operations and non-production use only.

Before you begin, consider that the commercially-available Nutanix NX Series systems are tuned forperformance. The enterprise-ready version of AOS is bundled as the engine driving our hyperconvergedcompute and storage platform. You should not expect to achieve comparable benchmark numbers. Forexample, the NX Series systems include 10 GbE network interfaces, high core count dual CPUs, largeamounts of memory, and high performance enterprise-class solid-state drives (SSDs).

Even so, Community Edition performance will be sufficient for a number of VMs per node, given enoughmemory, CPU, and network resources.

What's In Community Edition

Hypervisor Acropolis hypervisor with virtualizationmanagement

Single pane of glass control Prism web console to manage the cluster

Command-line management Nutanix command line (nCLI)

Ability to add nodes to the cluster One, three, or four nodes can comprise a cluster

Ease of installation and use Install and boot the hypervisor and AOSenvironment from USB device

Community Edition Licensing Requirements

To use the Community Edition, Nutanix requires the following actions and access. If you fail to meet theserequirements, access to your cluster will be blocked. The cluster remains operating but you will be unableto log on to it. Otherwise, there are no licensing file requirements as with the commercially-availableNutanix products.

Licensing Requirements

Requirement Enforcement

Admin account password change from default When you first log on to the Prism web consolewith the admin account credentials, you mustimmediately change the admin user password fromits default.

Nutanix Next account with log on credentials andthe Community Edition role enabled

After you first log on to the Prism web console andchange the admin credentials, you are prompted toprovide these credentials.

Outgoing TCP ports 80 or 8443 opened throughyour firewall

An automated feedback mechanism named Pulsethat sends cluster alerts and usage statistics toNutanix requires internet connectivity and portaccess.

Install any pending Community Edition updates Nutanix make updates available occasionally. Whenan upgrade is available, but not yet downloaded,you must upgrade within 30 calendar days. Youmust install the available upgrade immediately onceyou have downloaded it.

If you fail to meet these requirements, access toyour cluster will be blocked. The cluster remainsoperating but you will be unable to log on to it.

Preparing to Install Community EditionBefore you begin:

Before you install Community Edition:

1. Ensure that you have a valid account and log on credentials for the Next Community Edition forum, andthat the account has the Community Edition role associated with it.

2. Download the Community Edition software at the Community Edition forum topic Nutanix NextCommunity Download Software. The latest release is usually in the most recent topic in the thread.

3. Prepare the USB drive or other boot device with the downloaded image with your favorite imagingsoftware.

Tip: If you are using a Linux or Mac OS X environment, you can use the dd command to imagethe device:

dd if=ce.img of=/dev/sdX

where X is the USB drive letter.

• [Linux only] To find the USB drive letter, check the output of this command:

for i in /dev/sd?; do udevadm info --query=all --name=$i; done

• (OS X only) List any storage devices:

diskutil list

• (OS X only) Show information about a specific device:

diskutil info /dev/X

where X is the USB drive.

(OS X only) For improved performance when imaging, specify a block size of 1 MB. Forexample:dd if=ce.img of=/dev/rdisk2 bs=1m

What to do next: Have the following networking information ready for installation.

Caution: Nutanix recommends that you not use dynamic IP addressing for hosts or ControllerVMs. If you are using a DHCP server, ensure that it is set to assign static IP addresses for hostsand Controller VMs.

Community Edition reserves IP addresses 192.168.5.0 through 192.168.5.254 for internal use.Nutanix recommends using an IP address in the network ranges 10.x.x.x or 172.x.x.x for the Hostand Controller VM.

Creating a Single-Node Cluster

Before you begin:

Note:

• The login banner displays the Controller VM IP address.• Data resiliency is not applicable for single-node clusters; a single-node cluster does not provide

resiliency or high availability features, as multi-node clusters do.• Do not remove the USB drive or device at any time during your use of Community Edition.• A single-node cluster is created with a redundancy factor of 1. You cannot extend an existing

single-node cluster to a three- or four-node cluster, to automatically create a cluster withredundancy factor 2. To expand to a three- or four-node cluster when you have a single-nodecluster, destroy the cluster first, then create the new cluster. See Destroying a Cluster onpage 18.

Caution: If you created a single-node cluster during installation (that is, you selected the Createsingle-node cluster? checkbox) you do not need to perform this procedure. This topic is includedfor reference only.

1. At the login prompt shown after installing Community Edition, log on to the Community Edition host.User name is root and password is nutanix/4u.

2. Log on to the Controller VM through a secure shell session. User name is nutanix and password isnutanix/4u.For example: ssh [email protected]

3. Create the single node cluster, where cvm_ip is the Controller VM's IP address.

nutanix@cvm$ cluster -s cvm_ip -f create

Note: As of version ce-2015.11.05-stable, you do not need to specify the -f option. Thecommand is cluster -s cvm_ip create .

A series of messages displays, indicating that the cluster is being created and cluster services arestarting. When the process is finished, a cluster created message is displayed and the prompt returns.


4. Configure one or more DNS servers, then verify that the settings are in place.

nutanix@cvm$ ncli cluster add-to-name-servers servers="dns_server"

Replace dns_server with the IP address of a single DNS server or with a comma-separated list of DNSserver IP addresses.

nutanix@cvm$ ncli cluster get-name-servers

Creating and Configuring a Multi-Node Cluster (Web Browser Method)

Before you begin:

• Do not remove the USB drive or device at any time during your use of Community Edition.• If you are using Internet Explorer for Windows:

Note: Internet Explorer requires protected mode to be disabled. Go to Tools > InternetOptions > Security, clear the Enable Protected Mode check box, and restart the browser.

• If IPv6 link-local is enabled on the subnet, use the web browser option. If it is not enabled, use themanual command line option as described in Creating and Configuring a Multi-Node Cluster (ManualMethod) on page 17

• A single-node cluster is created with a redundancy factor of 1. You cannot extend an existing single-node cluster to a three- or four-node cluster, to automatically create a cluster with redundancy factor 2.To expand to a three- or four-node cluster when you have a single-node cluster, destroy the cluster first,then create the new cluster. See Destroying a Cluster on page 18.

1. Open a web browser and go to http://cvm_host_name:2100/cluster_init.html to create the cluster.Replace cvm_host_name with the IPv6 service name of any Controller VM that will be added to thecluster. Following is an example URL to access the cluster creation page on a Controller VM:

http://NTNX-12AM3K520060-A-CVM.local.:2100/cluster_init.html

2. Complete the following fields.

• Cluster Name. Type a meaningful value in this field. The maximum length is 75 characters. Allowedcharacters are uppercase and lowercase standard Latin letters (A-Z and a-z), decimal digits (0-9),dots (.), hyphens (-), and underscores (_).

• (Optional)Cluster External IP. You can connect to the external cluster IP address with both the webconsole and Nutanix command line (nCLI). In the event that a Controller VM is rebooted or fails, theexternal cluster IP address will be relocated to another Controller VM in the cluster.

• Cluster Max Redundancy Factor. Clear or set to 2 for three- and four-node clusters. By default,Nutanix clusters have redundancy factor 2, which means they can tolerate the failure of a singlenode or drive.

• Network settings. Type any network component IP addresses that were not detected duringinstallation.

• NTP servers. Enter NTP servers that the Controller VMs can reach in the CVM NTP Servers field.If reachable NTP servers are not entered or if the time on the Controller VMs is ahead of the currenttime, cluster services may fail to start.

• Discovered nodes. Select the check box next to each node that you want to add to the cluster. Allunconfigured nodes on the current network are presented on this web page. If you will be configuringmultiple clusters, be sure that you only select the nodes that should be part of the current cluster.

3. Click Create.Wait until the Log Messages section of the page reports that the cluster has been successfullyconfigured.


Output similar to the following indicates successful cluster configuration.Configuring IP addresses on node 13SM71450003/A...Configuring IP addresses on node 13SM71450003/A...Configuring IP addresses on node 13SM71450003/A...Configuring IP addresses on node 13SM71450003/A...Configuring the Hypervisor DNS settings on node 13SM71450003/A.......Initializing cluster...Cluster successfully initialized!Initializing the CVM DNS and NTP servers...Successfully updated the CVM NTP and DNS server list

The cluster is started automatically after creation.

4. You can log in to the Controller VM through an SSH session and check that the cluster started properlyby issuing a cluster status command. Each cluster service will show a status of UP if the clusterstarted successfully.

Creating and Configuring a Multi-Node Cluster (Manual Method)

Before you begin:

• Do not remove the USB drive or device at any time during your use of Community Edition.• If IPv6 link-local is enabled on the subnet, use the web browser option as described in Creating and

Configuring a Multi-Node Cluster (Web Browser Method) on page 16. If it is not enabled, use thismanual command line option.

• A single-node cluster is created with a redundancy factor of 1. You cannot extend an existing single-node cluster to a three- or four-node cluster, to automatically create a cluster with redundancy factor 2.To expand to a three- or four-node cluster when you have a single-node cluster, destroy the cluster first,then create the new cluster. See Destroying a Cluster on page 18.

Note: As described, this procedure is performed from the Community Edition hypervisor host. Youcan also perform it remotely by logging on to the Controller VM virtual IP address through a secureshell session. You specified this IP address as part of installation (Preparing to Install CommunityEdition on page 11).


2. Log on to the Controller VM through a secure shell session. User name is nutanix and password isnutanix/4u.For example: ssh [email protected]

3. Create the cluster.

nutanix@cvm$ cluster -s cvm_ip_addrs create

Replace cvm_ip_addrs with a comma-separated list of Controller VM IP addresses. Include allController VMs that will be part of the cluster. For example, if the new cluster should comprise fournodes, include all the IP addresses of all four Controller VMs

4. Start the Nutanix cluster.

nutanix@cvm$ cluster start

If the cluster starts properly, a series of messages is displayed for each node in the cluster, showingcluster services with a status of UP.


5. Set cluster parameters.

a. Define the name of the cluster.

nutanix@cvm$ ncli cluster edit-params new-name=cluster_name

Replace cluster_name with a name for the cluster of your choice.

b. Configure one or more DNS servers, then verify that the settings are in place.

nutanix@cvm$ ncli cluster add-to-name-servers servers="dns_server"

Replace dns_server with the IP address of a single DNS server or with a comma-separated list ofDNS server IP addresses.

nutanix@cvm$ ncli cluster get-name-servers

c. Configure the NTP servers.

nutanix@cvm$ ncli cluster add-to-ntp-servers servers="ntp_server"

Replace ntp_server with the IP address or host name of a single NTP server or a with a comma-separated list of NTP server IP addresses or host names.

d. Configure an external IP address for the cluster.

nutanix@cvm$ ncli cluster set-external-ip-address \ external-ip-address="cluster_ip_address"

Replace cluster_ip_address with a virtual IP address for the cluster.

This parameter is required for your Community Edition cluster.

Destroying a Cluster

Destroying a cluster resets all nodes in the cluster to the factory configuration. All cluster configuration andguest VM data is unrecoverable after destroying the cluster.

1. Log into a Controller VM through SSH.

2. Stop the cluster.

nutanix@cvm$ cluster stop

Wait to proceed until output similar to the following is displayed for every Controller VM in the cluster.

CVM: 172.16.8.191 Up, ZeusLeader Zeus UP [3167, 3180, 3181, 3182, 3191, 3201] Scavenger UP [3334, 3351, 3352, 3353] ConnectionSplicer DOWN [] Hyperint DOWN [] Medusa DOWN [] DynamicRingChanger DOWN [] Pithos DOWN [] Stargate DOWN [] Cerebro DOWN [] Chronos DOWN [] Curator DOWN [] Prism DOWN [] AlertManager DOWN [] StatsAggregator DOWN []


SysStatCollector DOWN []

3. Destroy the cluster.

Caution: Performing this operation deletes all cluster and guest VM data in the cluster.

nutanix@cvm$ cluster -f destroy

You can now recreate your cluster.

Install any pending Community Edition updates. As updates are made available in future, thisGetting Started guide will describe how to installthem.

Configuring Proxy Server Settings Before Logging Into the Web Console

If you are deploying Community Edition behind a proxy server, you need to use the Nutanix command lineinterface (nCLI) to configure a proxy server. This step helps ensure that Community Edition can validateyour credentials.


2. Log on to the Controller VM through a secure shell session. User name is nutanix and password isnutanix/4u.

https://www.youtube.com/watch?v=5JcYhvCbC3o




For example: ssh [email protected]

3. Create the HTTP/HTTPS proxy.

nutanix@cvm$ ncli http-proxy add name=proxy_name address=ip_addr username=user password=password port=8080 proxyTypes=http,https

The port number can be the common ports 8080 or 8443, or whichever ports are open through yourproxy server. Specify the proxy address as an IP address or domain name.

4. Ensure that proxy was added successfully by displaying the proxy settings.

nutanix@cvm$ ncli http-proxy ls

To update proxy settings, use the ncli http-proxy edit command with the same options above. Todelete the proxy, use the ncli http-proxy delete command with the same options above.

Logging Into the Web Console

Before you begin: Behind a proxy server? See Configuring Proxy Server Settings Before Logging Into theWeb Console on page 20 first.

To log into the web console, do the following:

1. Open a web browser and navigate to http://management_ip_addr. Replace management_ip_addr withthe IP address of any Nutanix Controller VM in the cluster.The browser will redirect to the encrypted port (9440) and may display an SSL certificate warning.Acknowledge the warning and proceed to the site.

2. First time logon: Do this step if this is the first time you have logged on to your Community Editioncluster.

a. Log on with the default admin account user name and password of admin).

b. When prompted, change the default admin password, then log on with the admin account user nameand new password.

c. Type your Nutanix Next Community account user name and password and press Enter or click theright arrow icon.

Click +Create Account if you have not joined the Next Community. Community Edition checks toensure that the Community Edition role associated with your account is enabled.

3. After logging on for the first time: Log on with the admin account user name and new password.

Creating the Datastore: Storage Pool and Container

1. Sign in to the Nutanix web console.

2. In the Storage dashboard, click the Storage Pool button.The Create Storage Pool dialog box appears.

For Community Edition clusters, if you name the container anything other than default you will needto use the --container parameter with the VM management scripts.


b. Storage Pool: Select the storage pool you created above from the drop-down list.The following field, Max Capacity, displays the amount of free space available in the selectedstorage pool.

Note: Advanced Settings include the ability to set the replication factor. For single-nodeclusters, you might see the alert message Replication factor of oplog on containerdefault is set to 1. Obviously, you cannot select a replication factor of 2, and, as a result,single-node clusters do not provide resiliency or high availability features, as multi-nodeclusters do.

c. When all the field entries are correct, click the Save button.

Creating a VM By Using the Web Console

You can create a new virtual machine (VM) through the web console.

To create a VM, do the following:
