一、操作系统环境准备
#确认版本、CPU和内存
#uname -r
#grep “model name” /proc/cpuinfo
#grep “MemTotal” /proc/meminfo
#cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)

#确认网卡名称
#ip addr

#设置网络信息
#nmcli connection mod ens33 connect.autoconnect yes
#nmcli connection mod ens33 ipv4.address 10.0.0.88/24
#nmcli connection mod ens33 ipv4.gateway 10.0.0.2
#nmcli connection mod ens33 ipv4.dns 10.0.0.2
#nmcli connection mod ens33 ipv4.method manual
#nmcli connection down ens33
#nmcli connection up ens33
#ip addr

#设置主机名
#hostnamectl set-hostname wdfstack
#echo “10.0.0.88 wdfstack” >> /etc/hosts

#关闭SELINUX
#setenforce 0
#vi /etc/selinux/config
SELINUX=disabled

#关闭防火墙和网络管理
#systemctl restart network
#systemctl stop firewalld.service
#systemctl disable firewalld.service
#systemctl stop NetworkManager
#systemctl disable NetworkManager

#重新启动机器
#sync
#reboot

#验证网络是否正常
#ping 10.0.0.88 -c5
#ping 10.0.0.2 -c5
#ping wdfstack -c5
#ping www.sina.com.cn -c5

#设置语言环境参数
#export LANG=en_US.utf-8
#export LC_ALL=en_US.utf-8

#刷新yum库
#yum clean all
#yum -y upgrade
#yum makecache
#yum list

二、配置软件源安装软件
#cd /etc/yum.repos.d
#yum -y install epel-release
#yum -y install centos-release-openstack-train
