Something I’ve been doing for a while is running ESXi on my home server setup. Up until now I’ve been running ESXi 5.5.x on a 2011 Mac Mini, but with the release of ESXi 6.0 by VMware, I decided it was time to upgrade to new hardware. I opted to use the 2012 Mac Mini Server over the 2014 Mac Mini because the 2012 Mini Server uses quad-core processors with hyper-threading. Hyper-threading effectively doubles the number of available processors, so I would be upgrading from four available processors on my 2011 Mini to eight available processors on my 2012; in turn doubling the number of virtual machines which I could host and run inside of ESXi.
Unlike my previous installation of ESXi 5.x on a 2011 Mac Mini Server, where I needed to add ethernet drivers to the stock ESXi 5.x installer, ESXi 6.0 will install and work without additional drivers or installer modification needed. All I needed to do was download a copy of the ESXi 6.0 installer ISO file from the VMware website, use Disk Utility to burn the ISO file to a CD and use that to install ESXi 6. For more details, see below the jump.
Installing ESXi 6.0 on the Mini
Once I had the CD, I hooked up an Apple USB SuperDrive to the Mini, popped the newly-burned CD in and rebooted the Mini. When rebooting, I held down the Option key on my keyboard to allow the various boot drive options to appear, then selected the CD. The CD showed up with EFI Boot and Windows partitions, so I selected EFI Boot.
NOTE: All screenshots of this process are from ESXi running inside of VMWare Fusion, but the Mac Mini install process was identical.
Once booted from the CD, I was asked to select the ESXi 6.0 installer. Once selected, the ESXi installer boot process began.
1. When asked to begin the installation process, I hit the Enter key.
2. I hit the F11 key to accept the license agreement.
At this point, the installer took a few minutes to scan the machine.
3. Once scanning completed, I was asked to select the drive I wanted to install on. I selected the drive I wanted and hit the Enter key.
4. I selected US Default for the keyboard layout.
5. When prompted, I set a password for the root account. This is the user account that you’ll initially use to log into your ESXi server.
At this point, the installer took a few minutes to scan the machine again.
6. The installer then confirms that you want to install using the options you’ve selected. You’re also warned that the disk will be repartitioned.
NOTE: Repartitioning will wipe everything on the drive. If you have data you need to get off of this drive, hit the Escape key to back out at this point.
7. ESXi 6.0 will then install.
8. When finished, the installer will request that you remove the installation disc and then reboot. Once you’ve removed it, hit the Enter key to reboot.
Booting ESXi 6.0 on the Mini and changing network settings
On reboot, the Mini should now boot from the newly-created ESXi boot drive. Once up at the server display screen, you should see that it’s picked up a dynamic IP from your DHCP server and has the hostname of localhost. Here’s how to change that to a static IP and a new hostname.
1. Click the F2 key.
2. Log in as the root account, using the password you set during the install process.
3. You should be now at the System Customization screen. Select Configure Management Network.
4. In the Configure Management Network screen, select IPv4 Configuration.
5. In the IPv4 Configuration settings, Select Set static IP address and network configuration: and hit the space bar to make that option active.
6. Set the static IP, subnet mask and gateway address. Once finished, hit the Enter key to save the changes.
7. In the Configure Management Network screen, select DNS Configuration.
8. In the DNS Configuration settings, set the address(es) of your DNS server(s) and also set your desired hostname. In my case, I set a fully qualified DNS name.
Once finished, hit the Enter key to save the changes.
9. In the Configure Management Network screen, select Custom DNS Suffixes.
10. In the Custom DNS Suffixes settings, you may need to set a DNS suffix. In my case, my domain was already filled in. Once finished, hit the Enter key to save the changes.
11. Once you’ve made all of your changes, hit the Escape key to exit back to the System Customization screen. You’ll be asked to confirm the changes you’ve made to your network settings and warned that there will be a brief network outage for the ESXi server and any VMs running on it. Hit the Y key to apply the new settings.
12. At the System Customization screen, you should now see your static IP and hostname displayed under Configure Management Network.
13. Hit the Escape key to exit to the server display screen. It should now be displaying your hostname and your static IP address.
Logging to your ESXi server
To log into your ESXi server, I recommend having access to a Windows VM or a Windows PC and running the Windows vSphere client for initial setup. Once you’ve got it up and running, VMware Fusion Pro has a number of ESXi management options.
1. Install the vSphere client on the Windows box.
2. Launch the vSphere client and enter the following information:
IP Address / Name: IP or DNS address of your ESXi server
User name: root
Password: the password you set during the install process
3. You’ll be warned that an untrusted SSL certificate is installed. Click the Ignore button.
If everything worked right, at this point you should be in! You’ll be warned that you’re using a 60 day evaluation license. If you have a VMWare account, you can log in to the VMWare website and download a free ESXi license to use with your Mini ESXi server.
