现在通常服务器最基本也配置了双网卡,服务器在上应用的时候通常这么设计,一个网卡分配业务应用网段,接收用户访问,一个网卡连接内部网段,连接数据库或NFS共享等类似应用,这样一来可以充分利用网卡带宽,提高网络效率。本文出自:http://koumm.blog.51cto.com
本文只是做了一个示例:
配置思路:
(1) 物理机双网卡,xen虚拟化平台也配置成双网桥。
(2) xen虚拟机也添加双网卡,分别桥网两个网卡,配置不同网段IP,内部网段可以不用配置网关。
1. xen主机上配置
1. 配置eth1网卡的IP地址
# vi /etc/sysconfig/network-scripts/ifcfg-eth1
并启动网卡:
# ifdown eth1 关闭网卡
# ifup eth1 启动网卡
2. 修改xen网桥配置配置文件
# cp /etc/xen/scripts/network-bridge /etc/xen/scripts/network-bridge.xen
# vi /etc/xen/xend-config.sxp
#(network-script network-bridge) 注释掉这行,添加如下一行
(network-script network-xen-multi-bridge)
3. 创建xenbr1网桥配置
# 创建另一个xenbr1配置脚本文件
# cd /etc/xen

# vi network-xen-multi-bridge #!/bin/sh # network-xen-multi-bridge # Exit if anything goes wrong.
set -e
# First arg is the operation.
OP=$ 1
shift script=/etc/xen/scripts/network-bridge.xen case ${OP} in
start) $script start vifnum= 1 bridge=xenbr1 netdev=eth1
$script start vifnum= 0 bridge=xenbr0 netdev=eth0
;; stop) $script stop vifnum= 1 bridge=xenbr1 netdev=eth1
$script stop vifnum= 0 bridge=xenbr0 netdev=eth0
;; status) $script status vifnum= 1 bridge=xenbr1 netdev=eth1
$script status vifnum= 0 bridge=xenbr0 netdev=eth0
;; *) echo 'Unknown command: ' ${OP}
echo 'Valid commands are: start, stop, status'
exit 1
esac |
# chmod +x network-xen-multi-bridge
4. 手工启动创建xenbr1网桥,并绑定eth1端口
手动执行创建虚拟网桥脚本
# /etc/xen/scripts/network-bridge.xen start vifnum=1 bridge=xenbr1 netdev=eth1
# 重启服务器
[[email protected] ~]# ifconfig

5. xen虚拟机上的配置
(1) 关闭xen虚拟机
# xm shutdown test01
(2) 修改xen虚拟配置文件
xen虚拟机通常也只有一个网卡,再加一网卡需要修改配置文件。
# vif = [ "mac=00:16:3e:27:ec:b9,bridge=xenbr0", "mac=00:16:3e:1a:00:01,ip=10.10.10.11,bridge=xenbr1" ]
(3) 启动xen虚拟机自动适应硬件配置
# xm create test01
修改eth1网卡IP地址,没有配置文件的话,可以直接复制eth0,修改上面的MAC地址,修改IP地址。
# vi /etc/sysconfig/network-script/ifcfg-eth1
本文只配置了一台xen服务器的网卡改造,另一台也按相同的方式进行配置。
至此,xen服务器双网卡配置完毕,有相同需求的情况可以按以上方式配置改造。
