I cannot seem to set a static IP address in the "firstboot" section of my kickstart script. The servers always come up using DHCP. I've used every flag in the Guides, and seen lots of sample scripts online, and just for good measure, I have thrown most of what I've found into the script, as seen below. To assign a static IP you have to create a portgroup first, assign your vlan if applicable add a vmkernel interface, and then assign the static IP, so it looks like this:.

Thanks for the help. It looks like I was close, but assigning a vmkernel interface should help a ton. I'll do a couple of test runs and post results soon. No problem.

I usually blow away the default network created by the network statement prior to the firstboot section. If you use this approach be sure to regenerate the certificates for the host, so you do not end up with certificate mismatch.

To regenerate the certs run. Quick question on this guys. IN redhat's kickstart it will actually take these options and use them to set the IP of the host.

In the kickstart you have the option to set a static IP on the networking options line. Thanks for the reply I was actually wanting to pass the parameters at the boot prompt of the iso so that we don't have to specify per ks.

William Lam said that passing the parameters at boot time will pass it through to the install. Sorry, I didn't realize you were asking about the boot options. You can pass parameters through on the kernel options line for sure. I do that and then read the log using a python script to grab the values. The error doesn't hurt anything, but it definitely stumped me for a bit. I just ignore it as I delete the default network in my kickstart and then load all my settings.

Do you have any examples on how you are doing that?Automating your ESXi builds is a great way of gaining efficiency and standardization. There are pros and cons of each way, with a networked unattended install we can modify our ESXi configuration relatively easy by editing the kickstart file that gets referenced each time, however, we are constrained to the requirement of having to be connected to the network at the time of the install.

Just starting out with VMware? Read this first. First of all, what is a kickstart file? A kickstart file is a text file containing the configuration typically used for Linux installations. ESXi is NOT based on Linux it does not use the Linux kernel, it uses its own proprietary VMkernel, however, there are many similarities to Linux and Unix-like OSes and being able to use kickstart files for configuring installs is one of them.

Below is a template of a kickstart file that can be used, we will use this for our demo. We have an ESXi host with a 4 port networking card. So when you look over the vSwitch configuring you can see we are adding all 4 of those ports to the vSwitch:.

Also, notice the section where we set the root password, this is the encrypted password hash of my password. This is the best practice for creating these kickstart files. Otherwise, people will be able to open up the. CFG file and see the root password in plain text.

How to Configure ESXi Unattended Installations: Part 1

So how do we generate our password hash? First, we need to install chocolatey. It allows us to install OpenSSL very quickly.

The password looks garbled up to us, but ESXi will still know what the password is. Using the password hash instead of a plain text password is little more secure to the human eye. To install chocolatey, run the following commands in an Administrative PowerShell console, then install openssl.

There are two bat files for installation. This will bring up a screen to install OpenSSL. Run through the installer window and now we have everything we need to generate our password hash.

Open up an administrative command prompt and type in the following two commands to generate your password hash. Now we have the password hash, copy that to the root password configuration section on the kickstart file and we are good to go. Now that we have our kickstart file created, we can test it. Run through the install and once completed, we can create our folder.

This allows us to specify the kickstart file for install. Next, we will take it a step further in part 2 where we will go over how to create an ISO to boot from that will let us skip typing in the location of the kickstart file. Download Altaro VM Backup.

To do so, you need a kickstart file, which can either be included in the ESXi image, or accessed by configuring the boot options of the host during the install, or via PXE boot. You can call the kickstart file from any of the following locations:.

Once you have your kickstart file in place, and accessible to your hosts, you need to edit the boot loader settings on the host in order to call the script. A example of the contents of a ks. You will then be presented with a prompt, where you can set the boot options referencing the ks. After hitting return, the installation will begin and the host will be configured with the settings defined in the ks. Other boot loader options include taken from VMware KB :. There is a default ks.

You can use this as the basis for your ks. The boot. The boot loader configuration file contains the following statements:. Generally speaking, if you have a small number of hosts to install, an interact installation is the best approach.

If you have a larger number of hosts then it is worth spending the time looking at automating the installations. Skip to content You can perform an unattended installation or upgrade of an ESXi host by using scripts.

Specify as a MAC address, for example, C This location can also be a vmnicNN name. If not specified and files need to be retrieved over the network, the installer defaults to the first discovered network adapter that is plugged in.

List of Tutorials. First, you need to access the Vmware web interface. Access the Port Groups tab. Click on the Management Network option.

On the next screen, you need to select the virtual management network interface. In our example, we selected the VMK0 interface. On the Top of the screen, click on the Actions menu and select the Edit settings option. On the new screen, you are able to perform the static IP address configuration.

After finishing the configuration, you need to click on the Save button. On the new screen, click on the Actions menu and select the Edit settings option.

First, we need to enable the SSH service to be able to remote access the Esxi server. Right click on the SSH service and select the Start option.

The Putty software is available on the putty. After finishing the download, run the software and wait for the following screen. On the prompt screen, enter the administrative login information. Use the following command to enter the Maintenance mode. Use the following command to perform the static IP address configuration. Use the following command to change the hostname of your Vmware ESXi server:.In this post we will enhance the PXE install with customized kickstart files specific for the hardware we want to install.

The kickstart file ks. The default and at this point only PXE menu is configured in the pxelinux. Even though many of them are for older ESXi versions they still apply. To tie this up to the pxelinux default menu or the default option in UEFI boot we will change the default file.

The first thing to understand is that the file needs to be available somehow. In our scenario we will use HTTP for delivering the file, and we will use the http service installed in the previous post. Google is your friend here This is split in two parts. This was straight forward on our servers apart from missing the ability to script it. The second part was the hardest to get right maybe because of missing googling skills on my part. Then I selected the wanted option and it loaded the installer.

The legacy option still works with the pxelinux. In addition to the default file which contains your PXE boot menu you will add a file named after the mac address of your host prefixed with a as in the UEFI example.

This file will have a specific menu with a default option pointing to your kickstart file. And now your PXE boot menu should include this option and optionally it will use it as the default and thereby having the installer load automatically after the specified timeout in this case you might want to set a lower timeout. Legacy boot syslinux Modify the default legacy PXE menu to include your script.
