 Configuring  ESXi 5.5 Host Step By Step Guide

 

In this section I will show you how to configure and connect to your newly installed ESXi 5.5 host. To begin open your virtual machine running your ESXi host or if it is a physical screen access the monitor. Once it has completely loaded up you should be looking at a screen similar to the one shown below. This shows the specs or the machine/vm and also give you some important information.

 config1

For most deployments you will want to configure a static ip address.  To do this you will need to log into the Host, Press “F2” to bring up the login screen.

config2

Enter your password for the root user account. If you have forgotten or lost this password you will need to do a complete reinstall to reset the password. Once logged in you should see the system menu. Select configure management network to continue

config3

Here we can setup the ESXi 5.5 Host’s management network settings. By default in my lab I only have 1 Nic card but if you had multiple nics for redundancy or for storage please make sure you have the correct nic/s selected. Once configured launch the “IP Configuration” menu

config4

Here you will configure you new static Ip address. Make sure to use your correct default gateway and subnet mask. Once everything is setup correctly hit “Enter” to finalize your changes

config5

For my Labs and most deployments I turn off IPV6, to do this select the IPv6 Configuration, Uncheck the enable box and hit “Enter” to save your settings

config6

Next we will configure DNS. Enter your Primary and Secondary DNS Server ip addresses. Also create you host name for the host. When finished hit “Enter to save”.  This is step 1 of 2 when configuring the DNS settings for a ESXi host. Next we will need to create the DNS entry on our DNS server.

config7

On your DNS Server you will need to create a new Host A record for the host. Browse to your Domains forward lookup zone, Right click and select New Host (A or AAA). Enter in your corresponding ip address and Host name. I also create a PTR record as well for reverse lookup. Click “Add Host” once finished and now your DNS entry should show up in Domains DNS.

Go back to your ESXi Host, Hit “ESC” To go back to the previous menu. Hit “Y” to apply your changes.

config10

 

 

 

Due to turning IPv6 off the host will need to be rebooted before continuing. Once the reboot has completed Log back in using your root account.

config11

Next we will select “Test Management Network”, Make sure your host name is correct and hit Enter to begin testing. If everything was setup correctly your new Esxi 5.5 host should pass. If everything checks out we can move on. If for some reason if failed, The ping checks are your gateway and DNS. If one of these fails check to make sure you have select the proper NIC and that it is cabled correctly. If your DNS name look up fails you may have configured DNS incorrectly on the server.

config12

 

Now in order to administer and begin using the ESXi host you need to download and install the vSphere client. At the main screen for your host it will tell you these tools can be downloaded via the host. Open up a browser window on your machine, Browse to your configured ip address.

config13

 

Click “Download vSphere Client” to begin the download.

 

Once finished Launch the .exe file to install vSphere.

config14

Launch vSphere

config15

Type in the Ip address of the Host you wish to administer, Also username will be root, type in your associated password. Once everything has been entered click “Login”

 config16

Select Install this certificate and Click “Ignore” to prevent getting this security warning message every time you launch vSphere.

 config17

Now you should load up into vSphere. You can now begin administering your ESXi host. From here you can apply license keys and begin creating VM’s. Ideally if you have more than 1 host you would want to use vCenter to gain further benefits.
