篇二:配置网络

场景要求:局域网内部相互访问、配置公网ip外部可以访问

一、系统初始化

  

二、配置网络

  1、设置网络为桥接模式

    

   2、设置网络参数:vi /etc/sysconfig/network-scripts/ifcfg-eth0 

    

   3、重启服务:service network restart

    

 

三、移植VM网络MAC地址变更

  场景:手动复制虚拟机的vdi文件,到另外一台机器上安装运行,MAC地址会是原先电脑上生成的,需要更新到新电脑上重新生成

  1、方式一

    导入好以后,在基础上复制一台,删除原先那台就OK

  2、方式二

##删除文件
rm -rf  /etc/udev/rules.d/70-persistent-net.rules

##重启
reboot

##重新启动后,进入查看,记住NAME、ATTR{address}
vi  /etc/udev/rules.d/70-persistent-net.rules

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

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

NAME对应DEVICE
ATTR{address}对应HWADDR

 参考

device eth0 does not seem to be present, delaying initialization

解决办法:
首先,打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示:
# vi /etc/udev/rules.d/70-persistent-net.rules
# 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 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
记录下,eth1网卡的mac地址00:0c:29:50:bd:17
接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0"  改成  DEVICE="eth1"  ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:0c:29:50:bd:17"
最后,重启网络
# service network restart
或者
# /etc/init.d/network restart
正常了。



如果文件改坏了:
删除: /etc/udev/rules.d/70-persistent-net.rules
重启:自动生成
