现象：宿主机与虚拟机能互相ping通，宿主机能ping通外网，但虚拟机ping不通外网

原因：vmware的网关设置有误

1）查看linux网络配置信息

1. [root@localhost ~]

cat /etc/sysconfig/network-scripts/ifcfg-eth0

2. DEVICE=eth0
3. TYPE=Ethernet
4. UUID=4af77be9-c7c7-4245-acac-afc2b7f91e49
5. ONBOOT=yes
6. NM_CONTROLLED=yes
7. BOOTPROTO=static
8. HWADDR=00:50:56:26:15:DE
9. DEFROUTE=yes
10. PEERDNS=yes
11. PEERROUTES=yes
12. IPV4_FAILURE_FATAL=yes
13. IPV6INIT=no
14. NAME="System eth0"
15. IPADDR=192.168.137.3
16. NETMASK=255.255.255.0
17. GATEWAY=192.168.137.254 #linux网关与vmware网关需一致才行
18. DNS1=114.114.114.114
19. DNS2=10.111.1.2

2）点击：虚拟网络编辑器

3）点击：更改设置 → VMnet8 → NAT设置

4）保持vmware网关是否与linux网关一致

5）重启网卡

1. [root@localhost ~]

service network restart

2. Shutting down interface eth0: [ OK ]
3. Shutting down loopback interface: [ OK ]
4. Bringing up loopback interface: [ OK ]
5. Bringing up interface eth0: Determining if ip address 192.168.137.3 is already in use for device eth0... [ OK ]

6）ping通百度

1. [root@localhost ~]

ping baidu.com

2. PING baidu.com (110.242.68.66) 56(84) bytes of data.
3. 64 bytes from 110.242.68.66: icmp_seq=1 ttl=128 time=60.3 ms
4. 64 bytes from 110.242.68.66: icmp_seq=2 ttl=128 time=64.3 ms
