Centos7镜像安装完了发现基础的ping/ifconfig命令都是无法使用
修改网络配置
将ONBOOT=no改为yes
vi /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=23b1ac4c-3d20-4d25-9c44-438c9c03845a
DEVICE=ens33
ONBOOT=yes //此处默认为NO改为yes

修改完毕后重启网卡
service network restart

ping一下看看网络通不通
[root@localhost ~]# ping www.baidu.com

安装基础命令依赖包
yum install net-tools.x86_64

安装完成后测试

基础命令正常使用后解决ssh连接的问题
1.查看开放端口
[root@localhost ~]# firewall-cmd --list-ports
1
2.如果没有开放22端口需开放22ssh端口
firewall-cmd --zone=public --add-port=22/tcp --permanent
1
3.重启防火墙
firewall-cmd --reload
1
4.修改虚拟机为桥接模式
注：修改桥接模式将虚拟机IP通过本机桥接外网则虚拟机和本机IP网段保持一直，可以通过ssh连接
1
5.通过Xshell等ssh连接虚拟机
ifconfig查看虚拟机IP
通过ssh连接此IP

总结
A 修改网络配置能够联网
B 安装基础命令依赖
C 开放相应端口，如需ssh则开启22
D 更改虚拟机为桥接模式IP网段保持一致
E 连接虚拟机
