Fedora配置静态IP地址+上网

1.首先声明，我是在虚拟机下配置上网:

  在VMWare的网卡设置里面，配置如下:

 

进入系统之后，默认IP地址是一个很奇怪的IP: 192.168.48.1

 

现在开始我们的工作:

1.[root@localhost /]# cd /etc/sysconfig/network-scripts/
2.[root@localhost network-scripts]# ls
ifcfg-eth0    ifdown-ipv6    ifup          ifup-ipx     ifup-sit
ifcfg-lo      ifdown-isdn    ifup-aliases  ifup-isdn    ifup-tunnel
ifdown        ifdown-post    ifup-bnep     ifup-plip    ifup-wireless
ifdown-bnep   ifdown-ppp     ifup-eth      ifup-plusb   init.ipv6-global
ifdown-eth    ifdown-routes  ifup-ippp     ifup-post    net.hotplug
ifdown-ippp   ifdown-sit     ifup-ipsec    ifup-ppp     network-functions
ifdown-ipsec  ifdown-tunnel  ifup-ipv6     ifup-routes  network-functions-ipv6
3.[root@localhost network-scripts]# gedit ifcfg-eth0

4.输入一些配置信息,我的配置文件最终如下:

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
HWADDR=00:0C:29:67:A2:13
IPADDR=192.168.1.157
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS=192.168.1.1
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet
PREFIX=24
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03

基本上都看的懂吧， 看不懂的话 就自己去找理解吧。

5.[root@localhost network-scripts]# /etc/init.d/network restart

 

基本的步骤就是上面一些，其实我配置的时候遇到了很多问题的，下面一一道来，如果你们也遇到的话，希望你们能参考一下我的解决方案。

1. 首先，我在ifconifg的时候，居然出现在我眼前的是 eth4, 不是eth0, 而在系统的/etc/sysconfig/network-scripts/目录下居然是ifcfg-eth0 , 当时我就傻眼了。

解决方案:

A. rm /etc/udev/rules.d/70-persistent-net.rules   (在删除之前，你们最好能备份一下，我是胆子大，什么都敢干的..)

B. reboot

C.重启动之后, cat /etc/udev/rules.d/70-persistent-net.rules

查看系统自动检测出的网卡相关信息,我的信息如下:

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x1022:0x2000 (vmxnet)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:67:a2:13", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

 

其中"00:0c:29:67:a2:13"就是我们要得到的具体信息了，==>> MAC地址。

D.cd /etc/sysconfig/network-scripts/
E.gedit ifcfg-eth0

F.将"HWADDR“参数修改为:  00:0c:29:67:a2:13

G. /etc/init.d/network restart

 H. ping 测试一下:
