安装虚拟机
下载rhel-8.2-x86_64-dvd.iso
安装vwmare
新建虚拟机，自定义
然后起名字，选择安装位置
处理器根据自己电脑配置
内存也是
根据自己的需求选择网络模式
创建虚拟磁盘，根据自己电脑大小分配空间
选择ISO文件，并开启虚拟机，选择开始安装
选择语言（我用的中文），确定source和system，点击install
设置root用户的密码
以及可以设置一个普通用户，静静等待几分钟
安装完成后会自动重启
安装完成
编写静态路由，ssh远程连接
cd /etc/sysconfig/network-scripts/
vi ifcfg-ens160
改
onBOOT=yes
BOOTPROTO=static
写（根据自己的网卡写）
IPADDR=192.168.91.100
NETMASK=255.255.255.0
GATEWAY=192.168.91.2
DNS1=192.168.91.2
重启虚拟机，利用ssh远程连接
安装yum和vim
