VMware-NAT模式下静态IP设置

1.NAT简单介绍

    NAT(Network Address Translation)，实现本机系统和虚拟系统的双向访问。但网络内其余机器不能访问虚拟系统，虚拟系统可经过本机系统用NAT协议访问网络内其余机器。在VM中由VMnet8提供IP，Gateway和DNS。

2.NAT静态IP简单设置

    a.查看nat模式下虚拟机的DNS

[root@rhel6 ~]# vi /etc/resolv.conf 
# Generated by NetworkManager
search local
nameserver 192.168.102.2  

    b.设置静态IP

[root@rhel6 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
#NM_CONTROLLED=no
BOOTPROTO=static
#BOOTPROTO=dhcp
IPADDR=192.168.102.136
BROADCAST=192.168.102.255
NETMASK=255.255.255.0
HWADDR=00:0C:29:9C:68:3D
GATEWAY=192.168.102.2
DNS1=192.168.102.2    

    c.重启network

[root@rhel6 ~]# /etc/init.d/network restart
Shutting down interface eth0:  Device state: 3 (disconnected)
                                                           [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  Active connection state: activated
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/5
                                                           [  OK  ]

   d.查看是否设置成功

        ifconfig

    好处：设置静态IP有利于采用虚拟机开发和调试。
