vps更換服務(wù)器后網(wǎng)卡不通的處理辦法：

更換網(wǎng)卡vps主機不通，在更換服務(wù)器的時(shí)候linux的主機時(shí)常遇到這類(lèi)問(wèn)題。

具體處理辦法是：

1.查看目前使用網(wǎng)卡和配置的實(shí)際mac地址（下面的使用的eth1）

[root@localhost ~]# vi /etc/udev/rules.d/70-persistent-net.rules 

顯示信息如下：（可能會(huì )多出一段是eth_sudu的）

# 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.

# net device ()

# net device ()

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:22:*", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# net device ()

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:4a:ff:2a:23:3d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
