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。但网络内其他机器不能访问虚拟系统，虚拟系统可通过本机系统用NAT协议访问网络内其他机器。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。
