有的時候當你用RAID從其他機器克隆一個系統到新硬碟中時,會出現新網卡不是從eth0開始,如果你想修改網卡從eth0開始,可以編輯"/etc/udev/rules.d/70-persistent-net.rules",如下
HostA:/dev # 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.
# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:a2:00:71", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
把eth1,改為eth0,保存后重啟.
重啟后發現機器ping不通,想辦法連接到console,ifconfig發現無eth1
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

原來剛才修改完文件后並未修改eth config文件.
HostA:~ # cd /etc/sysconfig/network/
HostA:/etc/sysconfig/network # mv ifcfg-eth1 ifcfg-eth0
HostA:/etc/sysconfig/network # /etc/init.d/network restart
eth0 Link encap:Ethernet HWaddr 00:50:56:A2:00:71

OK,網路設定已經完成,但是發現還是無法ping通該主機,但是可以從主機內ping通網關.原來還需要修改routes
HostA:/etc/sysconfig/network # vi routes
default 192.168.1.254 - eth1
把eth1修改為eth0.保存,重啟網路服務,ping通,搞定,收工
