Prepare You Environment As Joep mentions, you need to meet specific requirements for the CE. You can run a single node in a nested environment. I wanted to build a “proper” 3 node cluster but it couldn’t be done as you need an IPMI. This is what I’m building my node on: – 250GB SSD (Samsung Evo 840) – 32GB RAM – Intel i7-3770 @ 3.4 GHz – VMware Workstation 11 When you deploy the VM, you are deploying a Linux KVM Hypervisor with a nested “control” VM (CVM) inside that. The recommended minimum spec for this is 4vCPU, 16GB RAM and 200GB+500GB Disks. 1) Make sure you have signed up with Nutanix for the CE beta and downloaded the software (and unzipped the .IMG). 2) Renamed the .IMG to a .VMDK 3) Downloaded Joep’s disk descriptor file, renamed that too a .vmdk and store it with step 2. (As documented in Step 1 of his blog post). Build A Nutanix Node 1) First thing to do is create a VMware Workstation 11 VM with custom properties. I’m not going to list this off in detail, I’m just going to spam some pictures here as they’ll speak 1000 words.
2) The important part here is that for the first disk of the VM, attach an existing SATA disk. Select the image/disk descriptor file created in the above section.
3) At this stage, I powered on the VM to check that the NutanixCE boot screen appeared. Once it did, I shutdown the VM and set the following up.
4) I also noticed this prompt, I selected “Yes”.
5) When booted, follow the instructions and type install at the login.
6) Select the language and proceed on the setup screen
7) The system then checks your disks for performance. I passed all the tests because everything is virtualised on an SSD!
8) At the prompt, enter two static IP addresses from your subnet. One for your KVM host, one for your CVM. Read/accept the EULA and Start.
9) Allow the system to build out the hypervisor and CVM.
10) When complete, you should see Success! Press Enter and get to the KVM login prompt.
11) You can then SSH to the CVM that has been created (U: nutanix P: nutanix/4u). Create a cluster by running the following command.
12) Then setup Google as a name server for DNS.(This is for later when you have to validate your Nutanix account).
13) You can then navigate to your CVM via IP address provided in step 8. The first PRISM prompt is to change your admin password.
14) After this, login to PRISM using the new details. Then login with your NEXT Account credentials with which you signed up for the BETA.
15) You are then into PRISM, controlling your single KVM host and single VM.
Once you are logged in you can see the HTML5 GUI and drive the console around and create a VM if you so wish. Pretty cool stuff! It turns out I can’t create a cluster because I don’t have an IPMI address which is sought after when you try adding extra nodes! |
