Linux 网桥设置
在公司机房的物理机上架设 KVM虚拟化的时候,经常需要配置网桥,先要安装网桥工具:
apt-get install bridge-utils
apt-get install uml-utilities
编辑 /etc/network/interfaces,参考下面配置加入网桥配置信息:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
auto br0
iface br0 inet static
address 192.168.10.6
netmask 255.255.255.0
network 192.168.10.0
broadcast 192.168.10.255
dns-search dell1
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
auto eth1
iface eth1 inet manual
auto br1
iface br1 inet static
address 14.152.50.6
netmask 255.255.255.192
network 14.152.50.0
broadcast 14.152.50.63
gateway 14.152.50.1
bridge_ports eth1
bridge_stp off
bridge_fd 0
bridge_maxwait 0
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 114.114.114.114
dns-search dell1
auto eth2
iface eth2 inet manual
auto br2
iface br2 inet static
address 112.93.114.2
netmask 255.255.255.224
network 112.93.114.0
broadcast 112.93.114.255
gateway 112.93.114.1
bridge_ports eth2
bridge_stp off
bridge_maxwait 0
dns-nameservers 114.114.114.114
dns-search dell1
上面配置针对双线接入多 IP的情况,这样 br0-br2就可以给虚拟机 guest使用了,br0是内网,br1-br2是电信或者联通出口。
