linux 网络配置

1、配置IP和DNS

[root@1_5-xhf-app6 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1 
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
[color=green]IPADDR=192.168.1.57[/color]
PREFIX=24
[color=green]GATEWAY=192.168.1.254[/color]
DEFROUTE=yes
IPV6INIT=no
NAME="System eth1"
[color=green]DNS1=8.8.8.8
DNS2=8.8.4.4[/color]

2、配置机器名、网关

[root@1_5-xhf-app6 ~]# vi /etc/sysconfig/network
NETWORKING=yes
[color=green]HOSTNAME=1_5-xhf-app6
GATEWAY=192.168.1.254[/color]

3、配置host名映射

[root@1_5-xhf-app6 ~]# vi /etc/hosts
[color=green]127.0.0.1  localhost
192.168.1.57  1_5-xhf-app6[/color]

4、重启网络或者重启系统（ip和dns重启网络就行，机器名需要重启系统）

重启网络

[root@1_5-xhf-app6 ~]# service network restart
Shutting down loopback interface:  [  OK  ]
Bringing up loopback interface:  [  OK  ]
Bringing up interface eth1:  Active connection state: activated
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/2
[  OK  ]

重启机器

[root@1_5-xhf-app6 ~]# init 6
