centos下设置网桥
1、设置网卡
vi/etc/sysconfig/network-scripts/ifcfg-br0 DEVICE=br0 TYPE=Bridge ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=10.0.0.10 NETMASK=255.255.255.0 GATEWAY=10.0.0.254 DNS1=8.8.8.8 IPV6INIT=no USERCTL=no
vi/etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 HWADDR=BC:30:5B:CB:30:3F TYPE=Ethernet UUID=e513c376-2c85-45a7-92ba-d14ca2225e69 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=no #IPADDR=10.0.0.10 #NETMASK=255.255.255.0 #GATEWAY=10.0.0.254 #DNS1=192.168.1.250 #DNS2=192.168.1.251 #IPV6INIT=no USERCTL=no BRIDGE=br0
此步也可以这样设置网桥br0:
#brctladdbrbr0
#ipaddradd10.0.0.10/24devbr0
#iplinksetdevbr0up
2、关闭 NetworkManager
chkconfigNetworkManageroff serviceNetworkManagerstop
3、重启网络
servicenetworkrestart
4、查看网桥
[root@localhost~]#brctlshow bridgenamebridgeidSTPenabledinterfaces br08000.0050562539b9noens33
