RedHat 更改网卡

alibabamama

　　上个月有台RedHat服务器更换网卡，编译、安装驱动后 service network restart。提示更换的网卡不存在。ifconfig -a 发现有三个网卡： eth0 eth1 eth2。
　　vi /etc/udev/rules.d/70-persistent-net.rules
　　把没用的网卡(8139too)信息删除或注释掉，再修改新网卡(r8169)参数NAME="eth2"
　　

　　例子：

[root@smalarm rules.d]# cat 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 0x8086:0x1502 (e1000e)
