Virtual machine clone Linux centos6.5 system network card configuration graphic tutorial

As a newbie who has just come into contact with the Linux system, after installing the CentOS6.5 system on the VMware virtual machine, I cloned several copies of the pure system to facilitate later experiments. The cloning steps are very simple. The problem that occurs after cloning is that the MAC address of the cloned network card is the same as the MAC address of the original system. There will be a conflict in the local area network. The cloned MAC address needs to be changed, otherwise the network card will not start up. Today I will teach you how to modify it, as follows:

1. First enter the original system and use the command to view the network card information

2. Follow the same steps to enter the cloned system, check the network card address, and find that the MAC address is the same. Start the network service, and it will prompt "falied".

3. Edit the network card device: vi /etc/udev/rules.d/70-persistent-net.rules. The following content will appear. You can see that there are two network cards, eth0 and eth1. Eth0 is the cloned system, and eth1 is regenerated.

Add # in front to comment out the first network card, change the second network card to eth0, and record the mac address.

After editing is complete, press the Esc key to exit, and enter: wq to save and exit.

Then execute: vi /etc/sysconfig/network-scripts/ifcfg-eht0, replace the original MAC address with the MAC address just recorded, and then modify the IP address as follows.

4. Service network restart (if it fails, just restart the virtual machine)
After successful startup, you can use the ifconfig command to view the current IP

Ok, problem solved.
