1、分别使用vmware将两台linux虚拟机还原至安装的初始状态（前提是已经创建快照，实验目的是配置网卡信息，确保两台主机可以通信，因此需要两台虚拟机）
2、为了更加清晰的分辨两台主机，先分别配置主机名称，并查看系统版本
[root@linuxprobe Desktop]# vim /etc/hostname ## 修改虚拟机1主机名称
host1
[root@linuxprobe Desktop]# hostname ## 查看
host1
[root@linuxprobe Desktop]# hostnamectl ## 查看系统信息
Static hostname: host1
Icon name: computer
Chassis: n/a
Machine ID: 3475295383774df4b83491fd573fbbc2
Boot ID: 71ab80ee01054f5b84d6cd935259a977
Virtualization: vmware
Operating System: Red Hat Enterprise Linux Server 7.0 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.0:GA:server
Kernel: Linux 3.10.0-123.el7.x86_64
Architecture: x86_64
[root@linuxprobe Desktop]# reboot ## 重启，是主机名称生效
[root@linuxprobe Desktop]# vim /etc/hostname ## 修改虚拟机2主机名称
host2
[root@linuxprobe Desktop]# hostname ## 查看
host2
[root@linuxprobe Desktop]# hostnamectl ## 查看系统版本信息，也是RHEL7
Static hostname: linuxprobe.com
Icon name: computer
Chassis: n/a
Machine ID: 94333412b1ab4fb8b024d9b7038e4caa
Boot ID: 3998b9eeab3f45ffa78549f214f057ae
Virtualization: vmware
Operating System: Red Hat Enterprise Linux Server 7.0 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.0:GA:server
Kernel: Linux 3.10.0-123.el7.x86_64
Architecture: x86_64
[root@linuxprobe Desktop]# reboot ## 重启使主机名称生效
2、分别查看两台虚拟机的网卡信息
[root@host1 Desktop]# ifconfig ## 查看虚拟机1网卡信息，有网卡名称，MAC地址，但是没有IP信息
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ether 00:0c:29:e4:f7:b9 txqueuelen 1000 (Ethernet)

[root@host2 Desktop]# ifconfig ## 查看虚拟机2的网卡信息，有网卡名称，MAC地址，但是没有IP
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

3、分别修改两台虚拟机的网卡配置文件
