This article introduces the knowledge of "VMware cloning Linux tips can not find how to solve eth0", in the actual case of the operation process, many people will encounter such a dilemma, then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

What happened:

When you use the ifconfig command to modify the ip address of the virtual machine, it prompts eth0 that it cannot be found. It is useless to modify the configuration file / etc/sysconfig/network-scripts/ifcfg-eth0 directly and restart the system.

Using ifconfig to check, I found that there is no eth0, only eth3. So it should be time to create a virtual machine and recreate a network card. When the system finds that the network card is not unified with the system configuration, a new network interface is recreated.

Solution: configure eth0 back

Modify / etc/udev/rules.d/70-persistent-net.rules file

Comment PCI device 0x1022:0x2000 (vmxnet) with #, change the eth3 in PCI device 0x1022:0x2000 (vmxnet) to eth0, remember the MAC address ATTR {address} = = "00:0c:29:ab:c5:2c", and exit the save.

Modify the Nic configuration file / etc/sysconfig/network-scripts/ifcfg-eth0

Change the ip address: IPADDR=192.168.0.102 (because I only use the host-only link method, so it is static ip), modify the MAC address HWADDR=00:0C:29:AB:C5:2c, exit save.

Modify the hostname HOSTNAME=hadoop2 in the / etc/sysconfig/network file

Execute the command: service network restart, and you will be prompted that eth0 takes effect.

Bringing up interface eth0: Active connection state: activating

Active connection path: / org/freedesktop/NetworkManager/ActiveConnection/1

State: activated

Connection activated

It's better to restart the reboot.

[root@hadoop2 ~] # ifconfig
