《OD学hadoop》mac下使用VMware Fusion安装centos

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

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=1,0
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
