Server Instalation/Setup Guide

Post by ben_tvpp » 2018/12/05 11:56:43

I must be missing something but cant find the above. What I am looking for is the recommended way of setting up a basic server (no GUI/remote ssh access/networking). Lost of googling and searching these forums has not unearthed such a thing. Ive been setting up Linux servers for 15 years on and off and this is normally where I start.

The first thing I am trying to work out is which ISO should I use. Minimal or Netinstall.

Very odd.

There's a 0_README.txt in the /isos/ directory on all mirrors that contains the following explanatory text:

Code: Select all

List of images in this directory

  This DVD image contains all the packages that can be installed using the
  installer. This is the recommended image for most users.

  This is the network install and rescue image. The installer will ask from 
  where it should fetch the packages to be installed. This image is most 
  useful if you have a local mirror of CentOS packages.

  This image contains the complete set of packages for  CentOS Linux 7. It can be 
  used for installing or populating a local mirror. This image needs a 16GB USB 
  flash drive as it is too large for DVD isos.

  These images are Live images of  CentOS Linux 7. Depending on the name they use the
  respective display manager. They are designed for testing purposes and
  exploring the  CentOS Linux 7 environment. They will not modify the content of your 
  hard disk, unless you choose to install  CentOS Linux 7 from within the Live
  environment. Please be advised that you can not change the set of installed
  packages in this case. This needs to be done within the installed system
  using 'yum'.

  The aim of this image is to install a very basic  CentOS Linux 7 system, with the 
  minimum of packages needed to have a functional system. Please burn this image
  onto a CD and boot your computer off it. A preselected set of packages will be
  installed on your system. Everything else needs to be installed using yum. The set
  of packages installed by this image is identical to the one installed when choosing
  the group named "Minimal" from the full DVD image.

Using the installation images

You can burn these images to a DVD or 'dd' them to a USB flash drive. 
After the boot media has been prepared, boot the computer off the boot media. 
If you do an install to your hard disk using these installation images, please 
remember to run "yum update" after the installation to update your system to the 
latest packages.

Remember that in order to be able to partition your disk you will need to run
the GUI installer which in turns needs enough RAM. The same is true for the 
network setup step. Please refer to the release notes available at for more details about
these aspects.
Minimal iso is self-contained and needs no network to install a minimal system. Netinstall requires the network but otherwise functions exactly the same as the full DVD iso image except that it fetches all packages from the network. The DVD is also self-contained and needs no network access as all required packages are on the iso image itself.
CentOS 6 will die in November 2020 - migrate sooner rather than later!
Info for USB installs on
CentOS 5 is dead, do not use it.

Sorry, posted to wrong thread. I ended up going minimal.
