标签：ip地址   网络   网卡   桥接模式   nat模式   

一、桥接模式设置方法

[root@Centos66 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

TYPE=Ethernet

ONBOOT=yes  

NM_CONTROLLED=yes

BOOTPROTO=dhcp

HWADDR=00:0c:29:8d:e8:5b

DNS1=8.8.8.8

USERCTL=no

PEERDNS=yes

IPV6INIT=no

[root@Centos66 ~]# /etc/init.d/network restart

Shutting down interface eth0:  [  OK  ]

Shutting down loopback interface:  [  OK  ]

Bringing up loopback interface:  [  OK  ]

Bringing up interface eth0:  

Determining IP information for eth0... done.

[  OK  ]

二、NAT—静态ip地址配置上网

先设置网卡为NAT模式 

[root@Centos66 ~]#vi/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

TYPE=Ethernet

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=static

IPADDR=192.168.0.15

NETMASK=255.255.255.0

GATEWAY=192.168.0.2

HWADDR=00:0c:29:8d:e8:5b

DNS1=8.8.8.8

USERCTL=no

PEERDNS=yes

IPV6INIT=no

[root@Centos66 ~]# /etc/init.d/networkrestart

Shutting down interface eth0:  [ OK  ]

Shutting down loopback interface:  [ OK  ]

Bringing up loopback interface:  [ OK  ]

Bringing up interface eth0:  Determining if ip address 192.168.0.15 isalready in use for device eth0...

[ OK  ]

[root@Centos66 ~]# ping www.baidu.com
