Linux system installation

Linux system deployment environment preparation

Computer hardware environment: CPU-i5 memory-8G + hard disk-500g

Prepare for the virtual environment: windows-vmware 12 windows-- 15 architecture 64-bit

Operating system 32-bit: memory recognition capacity up to 4G memory recognition

Operating system 64-bit: memory recognition capacity up to 128G

First step: install the vmware software-- next step-- enter the activation code

Step 2: create a virtual host-- purchase a desktop

Step 3: configure virtualized network information

. Linux system installation and deployment process

The first step: download the system image / get the system CD
