1.安装软件包
yum install bridge-utils
目前的网卡状态:
[talen@sn192-168-1-65 etc]# ifconfig eth0 Link encap:Ethernet HWaddr 00:23:7D:33:CB:E4 inet addr:192.168.1.65 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::223:7dff:fe33:cbe4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:117061 errors:0 dropped:0 overruns:0 frame:0 TX packets:132280 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:19007683 (18.1 MiB) TX bytes:35575696 (33.9 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:198975 errors:0 dropped:0 overruns:0 frame:0 TX packets:198975 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:352654829 (336.3 MiB) TX bytes:352654829 (336.3 MiB) virbr0 Link encap:Ethernet HWaddr 52:54:00:F9:2C:D6 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:131 errors:0 dropped:0 overruns:0 frame:0 TX packets:94 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:13812 (13.4 KiB) TX bytes:11630 (11.3 KiB) vnet0 Link encap:Ethernet HWaddr FE:54:00:A0:E5:31 inet6 addr: fe80::fc54:ff:fea0:e531/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:52 errors:0 dropped:0 overruns:0 frame:0 TX packets:2567 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:7108 (6.9 KiB) TX bytes:135250 (132.0 KiB)修改宿主机的网卡配置
cd /etc/sysconfig/network-scripts ifdown eth0
ifdown eth0 修改eth0网卡的内容为: DEVICE=eth0 HWADDR=00:23:7d:33:cb:e4 ONBOOT=yes BRIDGE=br0
新建文件ifcfg-br0,添加如下内容: DEVICE=br0 ONBOOT=yes TYPE=Bridge BOOTPROTO=static IPADDR=192.168.1.65 GATEWAY=192.168.1.1 STP=on DELAY=0
重启网络服务: service network restart [root@sn192-168-1-65 network-scripts]# ifconfig br0 Link encap:Ethernet HWaddr 00:23:7D:33:CB:E4 inet addr:192.168.1.65 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::223:7dff:fe33:cbe4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:345 errors:0 dropped:0 overruns:0 frame:0 TX packets:353 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:47760 (46.6 KiB) TX bytes:71238 (69.5 KiB) eth0 Link encap:Ethernet HWaddr 00:23:7D:33:CB:E4 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:128269 errors:0 dropped:0 overruns:0 frame:0 TX packets:144974 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:20594100 (19.6 MiB) TX bytes:38646348 (36.8 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:217668 errors:0 dropped:0 overruns:0 frame:0 TX packets:217668 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:376131837 (358.7 MiB) TX bytes:376131837 (358.7 MiB) virbr0 Link encap:Ethernet HWaddr 52:54:00:F9:2C:D6 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:131 errors:0 dropped:0 overruns:0 frame:0 TX packets:94 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:13812 (13.4 KiB) TX bytes:11630 (11.3 KiB) vnet0 Link encap:Ethernet HWaddr FE:54:00:A0:E5:31 inet6 addr: fe80::fc54:ff:fea0:e531/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:52 errors:0 dropped:0 overruns:0 frame:0 TX packets:2973 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:7108 (6.9 KiB) TX bytes:156362 (152.6 KiB)虚拟机网卡选择br0就可以了.
