Eth0 cannot be found after VMware clones Linux

Eth0 cannot be found after VMware clones Linux

Occurrence:

I want to build a cluster quickly because I am learning Hadoop. Therefore, CentOS is directly installed on the Windows operating system with VMware. After configuring the hadoop development environment, the clone function is used to clone two other virtual machines.

However, when I use the ifconfig command to modify the Virtual Machine IP address, I am told that eth0 cannot be found. Directly modify the configuration file/etc/sysconfig/network-scripts/ifcfg-eth0, it is useless after the system is restarted.

You can use ifconfig to check whether eth0 exists. Only eth2. therefore, you should have created a new Nic when creating a virtual machine. When the system finds that the NIC and system configuration are inconsistent, a new network interface is created.

Solution: Configure eth0 back

Modify the/etc/udev/rules. d/70-persistent-net.rules File
Change eth2 in PCI device 0x1022: 0x2000 (vmxnet) to eth0 using # annotation, remember the MAC address ATTR {address }== "00: 0c: 29: AB: c5: 2c", and exit and save.
Modify Nic profile/etc/sysconfig/network-scripts/ifcfg-eth0
Modify the IP Address: IPADDR = 192.168.0.102 (because I only use the host-only link, so it is a static IP address). Modify the MAC address HWADDR = 00: 0C: 29: AB: C5: 2c, exit and save.
Modify the host name HOSTNAME = hadoop2 in the/etc/sysconfig/network File
Run the command: service network restart. A prompt message is displayed, indicating that eth0 takes effect.
Bringing up interface eth0: Active connection state: activating
Active connection path:/org/freedesktop/NetworkManager/ActiveConnection/1
State: activated
Connection activated

Restart reboot.
