As here already mentioned, you can run Domain controller either on baremetal or as VM. I prefer VM, as it gives you more flexibility and as DC require “low” CPU and RAM you don’t waste hardware resources of modern servers. AD infrastructure should be redundant, and it means that at least two DC must be deployed on different hardware servers. Failover ...

The -boot images are designed for installation over the network, external disk or a file server, typically used to install large numbers of computers. Additionally, the package collections allow the select a minimal setup. More info can be found here

This can be caused if the Windows Modules Installer service is disabled.

It seems that during the install, you answered "No" to the question "Use a network mirror?", and so your system left configured without a mirror (or maybe you didn't have a network connection during install). This, by the way, is indicated by your sources.list: # A network mirror was not selected during install. The following entries # are provided as ...

You can do it, using a script for a DHCP hook. Create a new file: sudoedit /etc/dhcp/dhclient-exit-hooks.d/hostname Paste the following code into the file, save and close: #!/bin/sh # Filename: /etc/dhcp/dhclient-exit-hooks.d/hostname # Purpose: Used by dhclient-script to set the hostname of the system # to match the DNS ...

It might be because you Calico's default POD CIDR conflicting with Host CIDR. Just got that impression from your --apiserver-advertise-address=192.168.178.33. If that is the case, worth trying out with a different POD CIDR --pod-network-cidr=20.96.0.0/12 with kubeadm init For a clean installation again, better do a kubeadm reset before the above changes. ...

2G won't cut it. Gitlab is a notorious memory hog. From the docs: https://docs.gitlab.com/ee/install/requirements.html 4GB RAM is the required minimum memory size Official doc states flat out "Gitlab has memory leaks" (https://docs.gitlab.com/ee/administration/operations/unicorn.html#unicorn-worker-killer) More details: https://about.gitlab.com/...

This is a situation where you should virtualize the workload. Use VMware ESXi or an open-source alternative to leverage modern hardware, coupled with a guest OS running the preferred variant of RHEL. Lean on your vendor to provide customer references or other examples of how this is handled in their other environments.

They clone an existing image. With a storage backend that uses deduplication cloning an image is practically instant. The most time is used booting the image, during this first boot a startup script is run that sets some settings (hostname, initial password, unique ID, stuff like this). Another option that even works on physical hardware is to have some ...

You somehow installed a package named mysql80-community-release intended for RHEL/CentOS 8, but your system is CentOS 7. This package provides the repositories to download MySQL, but it provides packages for RHEL/CentOS 8. This won't work on your system. You need to remove this package and replace it with its equivalent for CentOS 7, i.e. with yum remove ...

This is known ... thing ... in the ESXi installer from 6.0 on. Disconnect (physically remove) the FC cables (just leave them open for a few minutes) and setup will continue. After finishing setup, put the ports back in and everything will work like nothing happend. I once tried to find the "real" answer and got stuck somewhere between something ...

VDO and in particular its kernel module are built specifically for the associated RHEL/CentOS kernels. Your server, however, has OpenVZ, which uses a custom kernel. At this time using VDO with a custom kernel is not supported. In order to install this, you would need to obtain the source RPM for kmod-kvdo and then rebuild the RPM against the particular ...

This is because you are using Kerberos authentication, and you try to perform a "double hop", and this is not possible by default with Kerberos (basically, you can authenticate to "myserver", but you can't "hop" again to "fileserver"). What you can do: Copy the file locally on the server, and then remotely install the ...

The tutorial itself explains why this was done for /boot: Until there is support for mounting /boot in the initramfs, we also need to mount that, because it was marked canmount=noauto. Also, with UEFI, we need to ensure it is mounted before its child filesystem /boot/efi. Thus it instructs you to configure an /etc/fstab entry. In general you as an admin ...

maybe you would do this: using crontab -e * 20 * * * sh /path/to/myscript.sh using /etc/crontab * 20 * * * root cd /path/to/pluckeye/ && sh ./pluckeye-linux-0.99.40.installer

You will definitely need an answer file regardless of which way you want to use, if only for activation purposes. You can use answer files with any Windows installation media - Windows Setup automatically searches for a file called "autounattend.xml" in either the root folder of the installation media or the root folders of each attached USB media. So you ...

If you were tasked with setting up an AD infrastructure for multiple sites you should probably learn a bit more about the architecture than you will from random strangers on a tech forum. But to give you a meaningful answer: Pretty much any physical or virtual server capable of running a supported version of Windows Server should be capable of also running ...

Answer You do not need server racks. You need a computer to install Windows Server on. Once you have installed the operating system you install Active Directory onto that server. Your question requires too much explanation regarding Active Directory. You are essentially asking for the documentation regarding how to do a multi-site setup. Install it to ...

This is what happened. IN my home directory I had a program named copy.py, which was an example I use for teaching fileIO; it copies a file. It takes two command-line arguments and errors out if the user fails to supply them. Evidently, there is a module named copy that pandas uses. My copy.py got seen prior to the system's and it created this mess. ...

You need to set the DEBIAN_FRONTEND environment variable to noninteractive and pass the -y (yes) and -q (quiet) flags to apt export DEBIAN_FRONTEND=noninteractive sudo apt install -yq {PACKAGE} Credit: How do I ask apt-get to skip any interactive post-install configuration steps?

In my experience and across many .Net releases, very often the issue is that the .Net installer setup wants to launch the Windows Installer service, and if for any reason that fails to start it will sit there forever waiting. Manually starting the installer service via Admin Tools / Services will kick the progress back into life.

Calling sudo pip will call global pip and not pip in your virtualenv. Activate/Workon your environment then just call pip, not sudo pip, this may fix your issue, as it did mine.
