-----問題出現------
在新裝的ubuntu14.04系統中沒有發現文件/etc/udev/rule.d/70-persistent-net.rules, 無法修改網絡的邏輯名稱（即把第一張網卡的名字改為改為eth0，第二張網卡的名字改為eth0）
----------思路-----
1、由於未發現有/etc/udev/rule.d/70-persistent-net.rules文件，重啟；重啟后也未發現此文件
2、手動執行/lib/udev/write_net_rules;提示缺少變量INTERFACE
root@server:/lib/udev/rules.d# /lib/udev/write_net_rules missing $INTERFACE
增加變量：
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
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:1f:1a:f5", KERNEL=="eth*", NAME="eth0"
修改后：
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:1f:1a:eb", KERNEL=="eth*", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:1f:1a:f5", KERNEL=="eth*", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:1f:1a:ff", KERNEL=="eth*", NAME="eth2"
reboot，完畢
