Origin Linux

Developed by a 21-year-old boy named Linus Torvalds in 1991.

发行版

Ubuntu,RedHat,CentOS,openSUSE,Fedora,红旗Linux

Installation of Linux

We can visit the below urls to get the ISO.

https://wiki.centos.org/Download

Typically, we usually download the torrent file rather than iso then conduct the task on Thunder.

Then we can install the CentOS on Parallels Desktop.

After we login the Linux.

Excute the below command to get the Internet connectivity.

ip addr

Then we can see the item “eth0” where we need to fix doesn’t show the ip address.

cd /etc/sysconfig/network-scripts   // enter the directory to edit the file

vi ifcfg-eth0    //edit the file

change the last onboot = yes

ONBOOT=yes      

:x  //or :wq  to save end exit

reboot      //restart Linux System

Then we can connect remotely via SSH client.Here I list 3 kinds of clients

Terminal / iTerm

ssh -p $port $username@$ip

PS: FinalShell & NuoShell are developed by our Chinese! But it still takes long time to verify its safety anyway.
