Linux network card delay initialization error resolution

First, the problem description:
1. After configuring the network adapter configuration in the system, perform the network services restart prompt "Device eth0 does not seem to be present,delaying initialization."The device does not exist and the delay initialization error;
Service Network Restart
Bringing Up loopback insterface: [OK]
bringing up interface Eth0:device eth0 does no seem to be present,delaying initialization. [FAILED]

Ifconfig ... You do not see the eth0 and eth1 NIC devices.

2, check the/etc/sysconfig/network-scripts directory, network card configuration files are normal.

3. Entercd/etc/udev/rules.d/folder, check the MAC address in the 70-persistent-net.rules file with/etc/sysconfig/network-scripts NIC configuration file Ifcfg-eth0 and Ifcfg-eth1 MAC address are the same;

Second, problem solving:
1.go to the cd/etc/udev/rules.d/folder and back up the 70-persistent-net.rules file
MV 70-persistent-net.rules 70-persistent-net.rules.bak

2.Enter the Vi/etc/sysconfig/network-scripts directory toMAC address statements in Ifcfg-eth0 and ifcfg-eth1 filescomment out;
           #HWADDR = "74:a4:b5:00:82:8c"

3, reboot restart the server;

4, the server restarts after ifconfig in the View network card, found normal ping external address also all pass. Compare with previous file, find MAC address changed;

5.Enter the Vi/etc/sysconfig/network-scripts directory tothe MAC address in the Ifcfg-eth0 and ifcfg-eth1 files is modified to the new MAC address;

6,/etc/init.d/network Restart restart service after normal;
