操作首先修改/etc/udev/rules./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 0x8086:0x100f (e1000)
subsystem=="net", action=="add", drivers=="?*", attr=="00:0c:29:3d:56:58", attr
=="1", kernel=="eth*", name="eth0"
# pci device 0x8086:0x100f (e1000)
subsystem=="net", action=="add", drivers=="?*", attr=="00:0c:29:3d:56:62", attr
=="1", kernel=="eth*", name="good"
# 找到剛剛eth1的對應的實體地址，修改這一段的name中的字段，變成自己想要的
如何檢視網絡卡驅動，用ethtool -i eth1
[root@centos6 ~]# ethtool -i eth1
driver: e1000 #這行顯示驅動為e1000
version: 7.3.21-k8-napi
firmware-version:
bus-info: 0000:02:05.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
[root@centos6 ~]#
[root@centos6 ~]# modprobe -r e1000
這需要特別注意，由於我們的用的都是同一型號的網絡卡，所以驅動也一樣
雖然有兩個網絡卡，但是取得的都是一樣的，所以解除安裝之後不能上網，也遠端連線不了！！！！

Redhat CentOS修改網絡卡名
使用起來較為不便，因此我們將圖中的網絡卡名稱改為熟悉的eth0。1.首先將網絡卡配置檔案名稱重新命名為eth0 cd etc sysconfig network scripts mv ifcfg eno1677736 ifcfg eth0 將name引數改為與網絡卡檔案相同的名稱 name eth0...
