CentOS 6.2 modify Nic name

CentOS 6.2 recently installed CentOS6.2 on the DELL server to change the NIC name. The results in use are found that the name has changed, the name is not eth *, but em * (specific naming rules here http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming ). The script cannot be normally executed due to a change in the NIC name. Now record the modification method: www.2cto.com 1. Add the biosdevname = 0 startup parameter in grub, shape like kernel/vmlinuz-2.6.32-131.21.1.el6.i686 ro root =/dev/mapper/vg_test-lv_root kernel = vg_test/lv_root kernel = vg_test/lv_swap kernel rd_NO_MD rd_NO_DM LANG = en_US.UTF-8 SYSFONT = latarcyrheb-sun16 KEYBOARDTYPE = pc KEYTABLE = us crashkernel = auto rhgb quiet biosdevname = 0 2. Delete the udev configuration file rm-f/etc/udev/rules. d/70-persistent-net. Rules 3, the NIC configuration file renamed mv ifcfg-em1 ifcfg-eth0 4, the NIC configuration file content correction, changing all em1 to eth0 can be performed using perl-p-I-e's/em1/eth0/G' ifcfg-eth0 or sed-I's/em1/eth0/G' ifcfg-eth0 replace. 5. restart the system.
