一、搭建编译环境

安装编译环境

#yuminstallgccmakepython-developenssl-develkernel-develgraphviz\
kernel-debug-develautoconfautomakerpm-buildredhat-rpm-config\
libtool

编译rpm建议使用普通用户

下载创建编译目录脚本

$wgetftp://ftp.owlriver.com/pub/local/COLUG//RPM-build-tree.txt

执行脚本

$shRPM-build-tree.txt

rpmbuild
├──BUILD├──BUILDROOT├──RPMS
├──SOURCES
├──SPECS
└──SRPMS

二、编译openvswitchrpm包

##切换至家目录
$cd~
##下载openvswitch源码包
$wgethttp://openvswitch.org/releases/openvswitch-2.3.1.tar.gz

$cpopenvswitch-2.3.1.tar.gzrpmbuild/SOURCES/
$tarxvfopenvswitch-2.3.1.tar.gz
$cdopenvswitch-2.3.1
##编译内核
$cprhel/openvswitch-kmod.files~/rpmbuild/SOURCES/
$rpmbuild-bbrhel/openvswitch-kmod-rhel6.spec

##编译openvswitchrpm
$rpmbuild-bbrhel/openvswitch.spec

编译完成后rpm包位于

ll~/rpmbuild/RPMS/x86_64/
total11440
-rw-rw-r--.1firxiaofirxiao1223288Dec1705:50kmod-openvswitch-2.3.1-1.el6.x86_64.rpm
-rw-rw-r--.1firxiaofirxiao2640440Dec1706:01openvswitch-2.3.1-1.x86_64.rpm
-rw-rw-r--.1firxiaofirxiao7846548Dec1706:01openvswitch-debuginfo-2.3.1-1.x86_64.rpm

将openvswitch-2.3.1-1.x86_64.rpm kmod-openvswitch-2.3.1-1.el6.x86_64.rpm 上传至vm1、vm2

使用yum安装

#yuminstallopenvswitch-2.3.1-1.x86_64.rpmkmod-openvswitch-2.3.1-1.el6.x86_64.rpm

启动服务

#/etc/init.d/openvswitchstart

三、配置及使用

vm1vm2vm1andvm2创建桥接网卡ovsbridge0
--------基于ovsbridge0创建vlan100网卡。
eth0ech0
---------------------------
ovsbridge0ovsbridge0
172.16.0.20/24172.16.0.21/24
----------------------------
vlan100vlan100
192.168.100.2/24192.168.100.3/24
--------------------------------

将配置文件放于/etc/sysconfig/network-scripts

vm1网卡配置信息

配置好网卡后

#servicenetworkrestart

四、测试配置

在vm1 上 vm2 上使用 172.16.0.0/24可以互相通信

使用vlan100 192.168.100.0/24也可进行通信两个网络互相隔离
