centos 网络配置

1. /etc/sysconfig/network-scripts/ifcfg-ethO 修改

DEVICE=eth0
BOOTPROTO=none
HWADDR=B8:AC:6F:30:B9:CC
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.68.10
GATEWAY=192.168.68.254
TYPE=Ethernet
USERCTL=yes
IPV6INIT=no
PEERDNS=yes

2 /etc/init.d/network restart


3 使用虚拟机 桥接网络,能够使主机与虚拟机网络互通
若有冲突 device eth does not seem to be present 信息，
修改/etc/udev/rules.d/70-persistent-net.rules 内容

DEVICE=eth0
TYPE=Ethernet
UUID=1ecc6167-a5b9-4bf4-b1a7-d65b51a5b850
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
HWADDR=00:26:2D:F1:97:5C
PEERDNS=yes
PEERROUTES=yes
LAST_CONNECT=1413584692


DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
DEFROUTE=yes
IPV6INIT=no
HWADDR=08:00:27:7D:C6:0B
PEERDNS=yes
PEERROUTES=yes
NETMASK=255.255.255.0
IPADDR=192.168.10.5
GATEWAY=192.168.10.1
