一、 NAT模式网络访问
（1）在linux中输入命令ifconfig查看网络信息
（2）在mac中输入命令ifconfig查看网络信息
lo0: flags=<UP,LOOPBACK,RUNNING,MULTICAST> mtu
options=<RXCSUM,TXCSUM>
inet6 :: prefixlen

发现多了两个vmnet1，vmnet8接口，玩过VMware的都知道这是虚拟网络，vmnet1是host-only的方式，vmnet8是NAT的方式。
（3）查看VMware Fusion配置
@webm ➜ ~ sudo more /Library/Preferences/VMware\ Fusion/networking
VERSION=,
answer VNET_1_DHCP yes
answer VNET_1_DHCP_CFG_HASH ****
answer VNET_1_HOSTONLY_NETMASK 255.255.255.0
answer VNET_1_HOSTONLY_SUBNET 192.168.227.0
answer VNET_1_VIRTUAL_ADAPTER yes
answer VNET_8_DHCP yes
answer VNET_8_DHCP_CFG_HASH ****
answer VNET_8_HOSTONLY_NETMASK 255.255.255.0
answer VNET_8_HOSTONLY_SUBNET 172.16.53.0
answer VNET_8_NAT yes
answer VNET_8_VIRTUAL_ADAPTER yes
（4）编辑System ech0网络，
选择IP4Settings
Method选择"Manual"
点击Add
ip地址： 172.16.53.100
netmask： 255.255.255.0
gateway: 172.16.53.2
（5）vi /etc/sysoconfig/network-scripts/ifcfg-eth0
添加一行 DNS1=172.16.53.2（网关地址）
（6） vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=yeahwell.abc.com
（6）vi /etc/hosts
文件尾添加一行 172.16.53.100 yeahwell.abc.com
service network restart
（7）网络断开并重新连接
（8）ping www.baidu.com
