linux – 如何在RHEL 6.4 Server中配置绑定桥接器？

导读：已经安装了一个系统(rhel-server-6.4-x86_64-dvd.iso). KVM在哪集.主机和客机分配了自己的IP地址,为此桥接器配置了br0.一切正常.现在我们必须在结合方面建立一座桥梁. 将主机置于以下设置： [root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

已经安装了一个系统(rhel-server-6.4-x86_64-dvd.iso). KVM在哪集.主机和客机分配了自己的IP地址,为此桥接器配置了br0.一切正常.现在我们必须在结合方面建立一座桥梁.

将主机置于以下设置：

[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE=eth0
HWADDR=f0:92:1c:0f:76:f8
MASTER=bond0
SLAVE=yes
ONBOOT=yes

[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=F0:92:1C:0F:76:FC
MASTER=bond0
SLAVE=yes
ONBOOT=yes

[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0 
DEVICE=bond0
ONBOOT=yes
BRIDGE="br0"

[root@server ~]# cat /etc/modprobe.conf 
alias bond0 bonding
options bond0 mode=1 miimon=100

[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-br0 
DEVICE="br0"
NM_CONTROLLED="no"
ONBOOT="yes"
TYPE="Bridge"
BOOTPROTO="static"
IPADDR="10.2.26.39"
GATEWAY="10.2.26.1"
MTU="1500"
NETMASK="255.255.255.0"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="yes"
IPV6INIT="no"
NAME="System br0"

查看：

[root@server ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.6.0 (September 26,2009)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: eth1
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth0
MII Status: down
Speed: Unknown
Duplex: Unknown
Link Failure Count: 0
Permanent HW addr: f0:92:1c:0f:76:f8
Slave queue ID: 0

Slave Interface: eth1
MII Status: up
Speed: 10000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: f0:92:1c:0f:76:fc
Slave queue ID: 0

eth0失败了.虽然我期待看到如下内容：

[root@server ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.6.0 (September 26,2009)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None

Permanent HW addr: f0:92:1c:0f:d5:e8

Slave Interface: eth1

问题本身在一个主题中,如何在RHEL 6.4 Server中配置桥接绑定？

解决方法

这是正确的配置,但有几点：

>根本不需要别名bond0绑定
>绑定配置应该是ifcfg-bondX中的BONDING_OPTS,而不是modprobe
>在桥上添加DELAY = 0,以防止它在接口启动时等待

eth0关闭的事实与桥接或绑定无关,对物理接口进行故障排除. ethtool eth0将显示它没有检测到链接.

重新安装电缆,更换电缆,尝试不同的交换机端口,尝试不同的NIC.
