具体设置
1.首先设置成虚拟机与宿主机网络连接模式为NAT模式连接
2.修改虚拟机的网络与宿主机的内网段在同一网段,(在同一个局域网),这一点非常重要,不然不能通过宿主机的ssh来连接centos
VMware中: 编辑->虚拟网络编辑器
选中虚拟机所使用的网卡进行NAT设置:
从上图中可以发现宿主机的子网ip为:192.168.1.0
,所以我我们新增的网段只能为:192.168.1.x
要保证和宿主机同一个网段,然后设置两个映射入栈端口为22(ssh的登录端口号)验证设置
1.验证centos的网段是否是跟宿主机是否属于同一网段:192.168.1.x
(博主宿主机局域网段)
ssh登录虚拟机,成功登录,查看ip,可知跟宿主机在同一网段

2.验证centos是否可以上网:能ping通,上网正常.
