连网

一、固定ip网上方式

现在假设linux主机参数：

Hostname centos.dm.tsai

ip  192.168.1.169

Netmask 255.255.255.0

Network 192.168.1.0

Broadcast 192.168.1.255

Gatway 192.168.1.1

DNS ip 10.203.104.41

 

1、修改主机名称  /etc/sysconfig/network

NETWORKING=yes

HOSTNAME = centos.dm.tsai

 

2、网络参数设置 /etc/sysconfig/network-scripts/ifcfg-eth0

TYPE = Ethernet

DEVICE = eth0

BOOTPROTO = static

BROADCAST = 192.168.1.255

HWADDR = 00:23:D3:12:dd:12

IPADDR = 192.168.1.169

NETMASK = 255.255.255.0

GATEWAY = 192.168.1.1

DNS1 = 10.203.104.41

ONBOOT=yes

MTU=1500

 

3、启动与关闭网卡 ifup ifdown

ifup eth0

ifdown eth0

/etc/init.d/network restart

 

4、设置dns /etc/resolv.conf

nameserver 10.203.104.41

nameserver 202.96.128.166

 

nsloopup tw.yahoo.com

 

二、可自动取得ip的环境

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

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=dhcp

/etc/init.d/network restart
