CentOS6 配置Eth0


|字号订阅

1、在grub里增加biosdevname=0的启动参数，形如


kernel /vmlinuz-2.6.32-131.21.1.el6.i686 ro root=/dev/mapper/vg_test-lv_root rd_LVM_LV=vg_test/lv_root rd_LVM_LV=vg_test/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latar

cyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=auto rhgb quiet biosdevname=0

步骤：

首先cd /etc/sysconfig/network-scripts或者vi /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda2
# initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=5
splashp_w_picpath=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.32-220.17.1.el6.x86_64)

yrheb-sun16 rhgb crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM biosdevname=0
initrd /initramfs-2.6.32-220.17.1.el6.x86_64.img


[...]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

修改ifcfg-eth0：

DEVICE="eth0"

HWADDR="00:23:8B:37:4C:E6"

NM_CONTROLLED="yes"

ONBOOT="yes"

BOOTPROTO="none"

IPADDR="192.168.73.85"

NETMASK="255.255.255.0"

BROADCAST="192.168.73.255"

NETWORK="192.168.73.0"

IPV6INIT="yes"

IPV6_AUTOCONF="yes"

GATEWAY="192.168.73.252"

DNS1="218.2.135.1"

TPYE="Ethernet"

重启即可


在网络选项里吧P1P1改为eth0
