Error Installing CentOS 7

I received the error “This program has encountered an unknown error.” When installing CentOS. At the end of the report it had details about RAID and I remembered that the disk was part of a RAID.

To get rid of the RAID config:

  1. Restart the server.
  2. At the menu choose Troubleshooting Choose Rescue a CentOS system.
  3. You will be asked to make a selection, type in 1 and press enter. 
  4. You will see a prompt “Please press return to get a shell.
  5. Press the enter key Under “Rescue Mount” check which disk you need to configure i.e. sdb
  6. Now type: dmraid -E -r /dev/yourDisk i.e. (dmraid -E -r /dev/sda1)
  7. You will be asked if you want to erase “isw”. type y and press enter.
  8. Reboot your server and install CentOS 7

Here’s a video showing the screenshots I took:

Moving my server from Windows to Linux

I have moved from Windows to Linux on my laptop and gaming PC (Elementary OS) to be more specific and have not looked back.

My home server was running Windows Home Server 2011 and it seemed like I lost one of my disks with my music on. Windows could not see the disk at all but I could see the disk in the BIOS. I then booted into Linux using a USB thumb drive and managed to access the disk and it’s data so proceded to backup the data.

I then decided to get rid of Windows on my server and move to CentOS 7. I chose CentOS 7 as I am currently studying for my RHCSA

Below is the first video of the series. I stumbled across a few issues which I will be sharing soon.

How to make another version of Python the default version in Linux

In this post I show you how to make Python 3.7 the default version of Python on Linux. (This should work on all distributions of Linux).

My default version of Python was Python 2 and I needed to change it to version 3.7. 1.

Steps:

  1. Open your .bashrc file in your home directory using a text editor or the shell.
  2. Add alias python=’/usr/bin/pythonx.x’ to the file and save it. (x.x is your version that you want to be the default)
  3. Logout of your session or reboot your computer, then log back in.
  4. Open the terminal and then type in Python. It should now show you the version that you specified in the .bashrc file

Installing Virtual Box Guest Additions in Zentyal

I stumbled across Zentyal which seemed to be quite an interesting Linux distribution. I say that as they claim to be able to replace Microsoft’s Small Business Server (SBS) and co-exist with Active Directory and Exchange.

Have a look at their website for all the features.

I wanted to install the guest additions after installing Zentyal in Oracle’s Virtual Box to run the virtual machine in full screen mode. This was not as straight forward as I though it might be. Below is a video tutorial that I created to show how to install the guest additions in Zentyal. (Watch in HD and full screen)

Also note: the links below the video are for the sites I used to get this working.
