如何在 RHEL 6.4 Server 中設定綁定橋接？

已安裝系統（rhel-server-6.4-x86_64-dvd.iso）。 KVM 是透過哪個設定的。主機和訪客機分配了自己的IP位址，為該網橋配置布0。一切正常。現在我們必須在黏合上架起一座橋樑。

在主機上進行以下設定：

[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

乙太網路0是為。雖然我期待看到類似以下內容：

問題本身在一個主題中，如何在 RHEL 6.4 伺服器中配置橋接綁定？

答案1

這是正確的配置，但有幾點：

  • alias bond0 bonding你根本不需要
  • 綁定配置應與BONDING_OPTSifcfg-bondX 中相同，而不是 modprobe 中
  • 添加DELAY=0到您的網橋，以防止它等待介面啟動

eth0 關閉的事實與橋接或綁定無關，請對實體介面進行故障排除。ethtool eth0將向您顯示未偵測到連結。

重新拔插電纜、更換電纜、嘗試不同的交換器連接埠、嘗試不同的 NIC。
