一、搭建编译环境
安装编译环境
|
1
2
3
|
#yum install gcc make python-devel openssl-devel kernel-devel graphviz \
kernel-debug-devel autoconf automake rpm-build redhat-rpm-config \
libtool
|
编译rpm建议使用普通用户
下载创建编译目录脚本
|
1
|
$wget ftp://ftp.owlriver.com/pub/local/COLUG//RPM-build-tree.txt
|
执行脚本
将会在当前用户家目录创建如下目录
|
1

7
|
rpmbuild
├── BUILD
├── BUILDROOT
├── RPMS
├── SOURCES
├── SPECS
└── SRPMS
|
二、编译 openvswitch rpm包

##切换至家目录
$cd ~
##下载openvswitch源码包
$wget
$cp openvswitch-2.3.1.tar.gz rpmbuild/SOURCES/
$tar xvf openvswitch-2.3.1.tar.gz
$cd openvswitch-2.3.1
##编译内核
$cp rhel/openvswitch-kmod.files ~/rpmbuild/SOURCES/
$rpmbuild -bb rhel/openvswitch-kmod-rhel6.spec
##编译openvswitch rpm
$rpmbuild -bb rhel/openvswitch.spec
|
编译完成后rpm包位于
|

|
ll ~/rpmbuild/RPMS/x86_64/
total 11440
-rw-rw-r--. 1 firxiao firxiao 1223288 Dec 17 05:50 kmod-openvswitch-2.3.1-1.el6.x86_64.rpm

-rw-rw-r--. 1 firxiao firxiao 7846548 Dec 17 06:01 openvswitch-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
|
1
|
#yum install openvswitch-2.3.1-1.x86_64.rpm kmod-openvswitch-2.3.1-1.el6.x86_64.rpm
|
启动服务
|

|
#/etc/init.d/openvswitch start
|

配置好网卡后
三、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
编译rpm参考: openvswitch-2.3.1/INSTALL.RHEL
