如何在Linux服务器上配置网桥

1、建立网桥

touch /etc/sysconfig/network-scripts/ifcfg-br0

建立网桥配置文件ifcfg-br0

vi /etc/sysconfig/network-scripts/ifcfg-br0

2、添加网卡到网桥把eth0和eth1两网卡添加到网桥中。修改eth1网卡配置文件vi /etc/sysconfig/network-scripts/ifcfg-eth0

修改eth2网卡配置文件vi /etc/sysconfig/network-scripts/ifcfg-eth2

3. 重启网络服务

service network restart

在/etc/sysconfig/network-scripts/下

添加一个网桥的配置文件就可以了.

举例说明

假设你原来eth0的信息如下

cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

HWADDR="78:2B:CB:3C:A4:BA"

NM_CONTROLLD="yes"

ONBOOT="yes"

IPADDR=192.168.48.111

NETMASK=255.255.255.0

GATEWAY=192.168.48.1注释掉

BOOTPROTO

加入一行

vim

/etc/sysconfig/network-scripts/ifcfg-eth0

BRIDGE="br0"

新建一个网桥配置文件

vim

/etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0

TYPE=Bridge

ONBOOT=ye

BOOTPROTO=static

PREFIX=24

IPADDR=192.168.48.111

NETMASK=255.255.255.0

GATEWAY=192.168.48.1

STP=on

DELAY=0最后重启网络服务就可以了

/etc/init.d/network

restart
