Linux6-修改网卡名字：eth2—>>>>eth1
1、由于未发现有/etc/udev/rule.d/70-persistent-net.rules文件，重启；重启后也未发现此文件

2、手动执行/lib/udev/write_net_rules;提示缺少变量INTERFACE

root@server:/lib/udev/rules.d# /lib/udev/write_net_rules
missing $INTERFACE
增加变量：

root@server: export INTERFACE=”eth0″
missing valid match

root@server:export MATCHADDR=”00:0c:29:1f:1a:f5″

root@server:/lib/udev/write_net_rules

# ls /etc/udev/rules.d/
70-persistent-net.rules README

修改70-persistent-net.rules
