Occurrence:
Since learning Hadoop, so I want to quickly build out a cluster. So directly on the Windows operating system with VMware installed CentOS operating system, configured hadoop good development environment, the use of cloning feature directly cloned two additional virtual machines.
But when I use the ifconfig command to modify the virtual machine to modify the ip address, tell me eth0 not found. Directly modify the configuration file / etc / sysconfig / network-scripts / ifcfg-eth0, restart the system after it is.
Check with ifconfig only to find no eth0, only eth2. So it should be to create a virtual time machine, re-create a card. When the system finds the card with the system configuration is not uniform when re-creating a new network interface.
Solution: eth0 configuration back
Modify /etc/udev/rules.d/70-persistent-net.rules file
The PCI device 0x1022: 0x2000 (vmxnet) with a # comment, the PCI device 0x1022: 0x2000 (vmxnet) modify the eth2 eth0, remember that MAC address ATTR {address} == "00: 0c: 29: ab: c5: 2c ", save the exit.
Modify the network card configuration file / etc / sysconfig / network-scripts / ifcfg-eth0
Modify ip address: IPADDR = 192.168.0.102 (because I use host-only link mode, it is a static ip), modify the MAC address HWADDR = 00: 0C: 29: AB: C5: 2c, quit saving.
Modify / etc / sysconfig / network file hostname HOSTNAME = hadoop2
Run: service network restart, a message will appear eth0 effect.
Bringing up interface eth0: Active connection state: activating
Active connection path: / org / freedesktop / NetworkManager / ActiveConnection / 1
state: activated
Connection activated
Best reboot restart it.
