VMware 克隆CentOS (RHEL)后无法启动网卡服务的解决方法

首先要保证udev-post 启动

[root@localhost ~]# chkconfig --list udev-post
udev-post 0:off 1:on 2:on 3:on 4:on 5:on 6:off
[root@localhost ~]# /etc/init.d/udev-post start
Retrigger failed udev events [ OK ]
[root@localhost ~]#

将原有的eth0的那一行注释掉,然后将生成的eth1改为eth0

[root@localhost ~]# cat /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, and change only the value of the NAME= key.

# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8c:61:3e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:3c:e6:09", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
[root@localhost ~]#

最后修改网卡的配置文件

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=fb802c67-087a-4f50-812b-f3d20053aa4b
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
HWADDR=00:0C:29:3C:E6:09
IPADDR=192.168.100.212
PREFIX=24
GATEWAY=192.168.100.1
DNS1=192.168.100.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"

最后重新启动系统

[root@localhost ~]# reboot
