CentOS solves Device eth0 does not seem to be present

CentOS solves Device eth0 does not seem to be present

Centos Linux cloned from VMware ..

Ifconfig... the eth0 .. Then restart the NIC and report the following error.

Fault symptom:

Service network restart
Shutting down loopback insterface: [OK]
Bringing up loopback insterface: [OK]
Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [FAILED]

Solution:

1. Delete the UUID and mac address in eth0 and eth1.

2. Clear the mac address and UUID in the/etc/udev/rules. d/70-persistent-net.rules file.

[Root @ oldboy-35 ~] #>/Etc/udev/rules. d/70-persistent-net.rules

[Root @ oldboy-35 ~] # Echo ">/etc/udev/rules. d/70-persistent-net.rules">/etc/rc. local

[Root @ oldboy-35 ~] #

After clearing the file content, if you set up the network adapter address again, the mac address and UUID of the network adapter will be regenerated to/etc/udev/rules. d/70-persistent-net.rules. Therefore, if you need to edit the system configuration, you 'd better go to the configuration file to modify it, or go to setup. After the modification is complete, repeat the clear blank and delete operation.

If the mac address and UUID of the model board are not cleared, the above problem occurs after cloning, and the NIC cannot be started.

Finally, restart the network.

# Service network restart
Or

#/Etc/init. d/network restart

Normal.
