Welcome to Wildcard IT Training. This workshop is titled “Installing VMware ESXi 5.5".
The objectives of this workshop are listed on the right.
Press the 'Continue' button below to begin.
Before we install VMware ESXi 5.5, we must understand what a hypervisor is. There are numerous examples of a hypervisor – XenServer, Hyper-V and, of course, ESX are all hypervisors.
A hypervisor is software that is installed onto a server to allow the creation, running and administration of virtual machines. A virtual machine behaves in the same way as a physical machine.
ESX is a Type-1 hypervisor as it is installed directly onto a host's hardware. A Type-2 hypervisor, such as VMWare Workstation, runs on conventional operating systems such as Windows 8.
The screen on the right shows us our server which has booted from the ESX5 5.5 CD.
Press the 'Enter' key to continue the install.
There are a huge amount of advantages to utilizing virtual machines.
We can do more with the server hardware we have. As the majority of physical servers are likely to be under-utilized, we can create high density deployments to get the most out of our resources.
As virtual machines on the same host are segmented, we can run many applications and operating systems that have different requirements on the same server.
In a later workshop of vCenter, we will see how we can create high availability of virtual machines in a robust and straight-forward way.
We are prompted to read and accept the End User License Agreement from VMware. In the real world we should read this fully.
Press Enter to accept.
We are prompted to select a disk to install ESX 5.5 on.
The disk space requirements are very low with only 1GB required. It is for this reason that servers often ship with a SD card of only a few gigabytes in size.
This storage does not need to be fast as when ESXi boots the hypervisor is loaded into RAM and run from there.
If we had more than one disk installed, either locally or remote, we would need to ensure we have the correct one selected before confirming the install.
It is possible to create an 'Auto-Deploy' installation but this is out-with the scope of this workshop.
Press Enter to continue.
Now we should select the keyboard layout for this installation.
It is possible to change this after the ESXi has been installed but the next step of this install process is to create a password. We should therefore ensure we select the keyboard layout we are accustomed to so as to ensure we input the correct characters.
In this case, leave the 'US Default' selected and press Enter.
We must now enter a root password and confirm this.
It is possible to leave this blank but even for testing purposes it is a good idea to retain security protocol.
There are no complexity requirements for this password.
We need to ensure we enter this password carefully and confirm it as we require it to log into the ESXi host later in this chapter.
Enter a password of your choosing, confirm it and then press Enter.
The installation has completed successfully.
ESXi 5.5 begins in evaluation mode which lasts for 60 days unless we assign a licence key to it. Will learn how to do this in a later workshop.
We would remove the installation disk from the server before rebooting.
Press Enter to reboot the server and begin the loading of ESXi 5.5.
We have successfully installed ESXi 5.5 and it has booted as expected.
From this console session there is little administration that can be done. We cannot manage virtual machines from this console, we need to log into it remotely.
However, we firstly need to assign an IP address to this ESXi host. This could be done by including a DHCP server on our network. In this case, we will set a static IP address.
We must ensure this IP address is accessible from the server or workstation that we wish to manage the creation and administration of virtual machines.
To set this address statically, we need to customize the system.
Press F2 to do this.
We need to firstly login.
This is the password we set during the installation process.
Enter this now and press Enter.
Now that we are logged in we can customize the system.
The 'Configure Password' option allows us to change the password we had set. As we learned earlier, we can change the keyboard layout by selecting 'Configure Keyboard'.
The 'View System Logs' option allows us to perform detailed system analysis if required for troubleshooting purposes.
To get us started, we need to select 'Configure Management Network'.
Using the keyboard, move the highlighted option down.
On the right of the screen we can see a very brief summary of the current management network settings.
The management network and IP address is what we access to manage and administer virtual machines.
The IP address 169.254.82.127 is an APIPA address that is automatically assigned when there is no DHCP server in the network.
Press 'Enter' to configure the management network.
An ESXi server would usually have numerous network interfaces to ensure the redundancy and bandwidth requirements of multiple virtual machines are met. We therefore need to ensure the management network is configured on the correct interface.
Select the 'Network Adapters' option by pressing 'Enter'.
This ESXi server has five physical network interfaces installed.
VMnic0 is currently selected as the only adapter that will provide the host's management network. We can select multiple network interfaces to provide fault tolerance but in this case we can leave just one selected.
It is possible to use VLAN tagging on the management interface if we wanted to trunk interfaces. This is out-with the scope of this workshop.
We should be certain that the network interface case selected is on the correct network.
Press 'Enter' to confirm this.
Now use the keyboard to move down to 'IP Configuration'.
Now use the keyboard to move down to 'IP Configuration'.
With the 'IP Configuration' configuration option selected, press 'Enter'.
Even if we did have a DHCP server on this network it would be wise to remove the dynamic IP address and set it statically to ensure we receive the same IP address at all times.
Move down to 'Set static IP address and network configuration'.
We now have to select the 'Set static IP address and network configuration'.
Do this by pressing 'Space' on the keyboard.
Now that we have the static option selected we can edit the IP address, subnet mask and default gateway.
Move down to IP address and we will set this manually.
In the IP Address field enter:
and then move down to select the subnet mask.
The subnet mask we enter is used to establish whether other hosts that this ESXi server is communicating to are on the same network or whether the request should be sent to the default gateway to route to another subnet.
We will create a 24-bit subnet mask.
Enter this in the format:
We will not set a default gateway at this point.
Press Enter to confirm these IP configuration changes.
We can see a brief summary of our new static IP address assignment.
Before these changes take effect, we need to restart the management network of the ESXi host.
Press 'Esc' to exit this screen.
We are told we have made changes to the host's management network and applying these will result in a brief outage.
Press 'Y' to apply these changes and restart the management network of the ESXi host.
The management network has restarted successfully and we are returned to the original screen of the ESXi host.
We can see that we can download tools to manage the ESXi host from the IP address that we statically set.
We could, of course, create a DNS record for this to ensure we had an easy to remember hostname such as ESX01.
Let's now attempt to manage this host.
We will connect to a Windows 8.1 workstation named WCPC01 and connect to our ESXi host remotely.
Press 'Continue' below to connect to WCPC01.
We are now connected to WCPC01.
Before we can manage our ESXi 5.5 host we must download the tools to do this.
The native tool is the VMware vSphere Client that can be downloaded from the VMware website.
Thankfully, when we browse to our ESXi host we are given a link rather than having to find it.
Let's browse to our ESXi host using the static IP we just setup.
Remember, this WCPC01 workstation must have network connectivity to the ESXi management network. In this case, it is on the same subnet so there will be no issues.
Select Internet Explorer from the task bar.
In the address bar, input the static IP address we setup. This was:
and then press 'Enter' to navigate to it.
We are given a warning that the security certificate was not issued by a trusted source.
Certificates are used to encrypt network traffic between two endpoints. Browsers will by default only trust certificates issued by a few verified companies such as Verisign, Comodo, Synamtec etc. The certificate this ESXi host uses is issued by itself.
This means that although the traffic is still encrypted, Internet Explorer does not have the ESXi host as a trusted issuer of certificates.
This can be solved by either changing the certificate to one issued by a company that browsers trust of by telling our computer the current certificate should be trusted.
In this case, we can select 'Continue to this website'.
We are now connected to the ESXi server we just installed and configured.
However, no management can be performed from this web page.
We need to download the vSphere Client.
Click on the link named 'Download vSphere Client'.
We can simply select 'Save' when prompted what to do with the EXE file.
Once the download has completed, select 'Run'.
This will launch the vSphere Client installation process on the workstation we are currently connected to.
The install wizard for the VMware vSphere Client 5.5 has begun.
When prompted for the language for the installation to be completed in, leave the default 'English (United States' selected and press 'OK'.
Begin the installation by pressing 'Next'.
In a real world scenario we should read the VMware end user license agreement.
In this case, simply select 'I accept the terms in the license agreement'.
Now continue the installation process by selecting 'Next'.
We can change the location of the vSphere Client 5.5 installation but for this workshop we will leave this as default.
Select 'Next' to continue.
Confirm we are ready to install the program by pressing 'Install'.
We are told the VMware vSphere Client 5.5 has been installed successfully.
Press 'Finish' to close the wizard.
Now we wish to use the client to connect to the ESXi we setup and configured.
A shortcut to the vSphere Client will be on the desktop.
Access this by closing the Internet Explorer window using the X at the top right of the screen.
We can now see the shortcut to the VMware vSphere Client 5.5 on the desktop.
Launch this by double clicking on it.
Enter the IP address to the static assignment we earlier defined:
Enter the username to be the default administrative account:
Finally, enter the password you previously setup.
Confirm the details by pressing 'Login'.
We receive the same security warning regarding the untrusted certificate.
This is for the same reason we previously learned.
Continue by pressing 'Ignore'.
We have finally logged into our ESXi host with the IP address 172.16.3.13.
We are firstly greeted with a warning that our evaluation will expire within 60 days.
We will see how to assign a licence in another workshop.
Press 'OK' to continue.
Select the 'Inventory' icon to view the ESXi host we created.
On the left we can see our ESXi 5.5 host, 172.16.3.13.
There are numerous tabs at the top of the screen, from Summary, Virtual Machines, Resource Allocation, Performance etc.
We will explore these in future workshops.
From this point, we can create several virtual machines with this ESXi server. We will look at doing this in future workshops.
Press the 'Continue' button below to proceed.
Let's review the objectives of this workshop.
We installed ESXi 5.5, setting the root administrative password. We ensured we had the correct network interface selected for the management network and we gave this interface a static IP address.
We downloaded the vSphere Client onto WCPC01, installed it and logged into our ESXi host using the client.
To continue our learning about VMware, select 'Next Workshop' in series where we create a virtual machine.
Use the 'Home' or 'Contents' link at the top of this page to navigate around the Wildcard IT Training website.
