Install Centos and CRTM

Refresher (Last time I used Linux is 4 months ago and I almost forgot everything)

• robo vm is 3 GB .vmdk file, password: robo-nd
• open terminal: ctrl + option + t

main take-away:

1. use stable version of VirtualBox(older version)
2. use ready-to-use version of centos VM. So you have GUI and Firefox.

install on Mac OS, fail

cd config-setup
chmod u+x gfortran.setup  # change user access to write

install on Ubuntu, fail

install on Centos 7 DVD ISO, but no GUI

install virtual box on macOS High Sierra

Virtual Box 5.2.6 doesn’t work on macOS High Sierra. Use VirtualBox 5.2.4. https://www.virtualbox.org/wiki/Download_Old_Builds_5_2

Installation failure? System configuration -> Seurity & Privacy -> authroize changes ( the lock sign)

install centos on virtual box

Installing Centos 7 on VirtualBox: https://www.youtube.com/watch?v=O1nF7HQAJGw

Virtual box - new -> name: centos7 -> next -> 2048 MB->create a virtual hard disk now -> Hard disk file type: VDI -> dynamically allocated

Localhost login: root

Password: wnixxxxxxx

add user

adduser yuchao
passwd yuchao
usermod -aG wheel username

CentOS 使用 yum，Ubuntu 使用 apt-get，近些年又出现了一些与发行版无关的第三方包管理器，比如 Linuxbrew.

The problem is no GUI, so inconvenient to use. May try everything ISO next time.

install on Centos, ready-to-use VirtualBox by OSBoxes, success!
