First, download the ISO installation file for CentOS Linux 7, which uses the Minimal ISO. The downloaded ISO file will be written to the USB flash drive using Fedora Media Writer. Minimal ISO is a minimal installation, usually can be easily set up in the graphical interface, such as setting the time zone, hard disk partition, setting the password of the root user, and other settable items.

Then, after waiting for the installation to complete, you can start the dhcp service to get the machine's ip address, so that we can log in through the ssh software and then execute the command.
[root@localhost ~]dhclient
[root@localhost ~]# ip a
1: lo:  mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp0s3:  mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:cc:59:fa brd ff:ff:ff:ff:ff:ff
    inet brd scope global dynamic enp0s3
       valid_lft 86370sec preferred_lft 86370sec
Set the machine name
hostnamectl set-hostname atlantis1
Install wget, vim, emacs and other software
yum install wget -y

If the server accesses the YUM official software repository is slow, you can configure the mirror address of the YUM source.
cd /etc/yum.repos.d/
mkdir repo.bak
mv *.repo repo.bak/

wget http://mirrors.aliyun.com/repo/Centos-7.repo
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

yum clean allyum makecache
yum list | grep epel-release
yum install -y epel-release

wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.rep

yum clean all
