vmware中，如何修改网卡的名字

郑全

在使用vmware 做rac的过程中，安装了第一台机器后，再安装另一台机器时，一般可以通过拷贝前一台机器的方式来完成，
但我们拷贝过来后，发现网卡的名字不一样了，比如第一台机器的网卡为 eth0,eth1,但发现拷贝过来后，网卡名字为eth1,eth2了，
如果通过删除网卡，再增加网卡的方式，发现网卡一直在往前面增长，如下：




比如上面，复制后，变成eth4,eth5了，这个时候如何处理呢？

其实，在/etc/udev/rules.d/70-persistent-net.rules中，有这个记录:

[root@rac1 rules.d]# pwd
/etc/udev/rules.d
[root@rac1 rules.d]# more 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{address}=="00:0c:29:20:dd:f2", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:20:dd:fc", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:d1:a3:8f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:d1:a3:99", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:23:de:d9", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:39:df:1e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5"
[root@rac1 rules.d]#



把前面的部分删除，只留最后两行，同时修改NAME

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:23:de:d9", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:39:df:1e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

之后，重启机器，再查看，

我们将看到网卡名字已经变了

cd /etc/udev/rules.d
60-net.rules(RHEL5)
70-persistent-net.rules (RHEL 6)
RHEL 5和6有略微的区别
