CentOS 7 minimal install
This post shows a small installation guide on how to install a Cent OS 7 minimal iso.
- Download the Minimal iso at https://www.centos.org/download/
- Setup a VM, I use VMWare Fusion here. With the following resources:
- 2 Cores
- 4 GByte RAM
- A disk with 20 GByte with 2 GB for /boot, 8 GByte swap and 10 GByte for /
- A disk with 20 GByte for /data
- Choose Etc/UTC as timezone and partition the system to use the first disk with the our choose layout.
Now we have to fix the network link, for the beginning I use a NAT ethernet to avoid external take over, before I’m finished with the installation.
