Distributed Virtual Switch인 OVS (Open vSwitch)를 정리 합니다.

OVS 개요

Linux의 상단에서 가상의 L2 Switch를 생성합니다. 정교한 패킷 제어 기능을 제공하는 OpenFlow 프로토콜을 지원 합니다.

  • NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag 지원

Open vSwitch 설치

Source로 설치

  • RPM 생성을 위한 환경 구성
yum install -y rpm-build
yum groupinstall -y "Development Tools"

yum install -y openssl-devel
yum install kernel-devel

mkdir -p $HOME/rpmbuild/SOURCES

$HOME/rpmbuild/SOURCES/
wget http://openvswitch.org/releases/openvswitch-2.3.0.tar.gz
tar xvfz openvswitch-2.3.0.tar.gz
cd openvswitch-2.3.0

vi rhel/openvswitch.spec
 ### Requires: openvswitch-kmod, logrotate, python
 Requires: logrotate, python

rpmbuild -bb -D `uname -r` rhel/openvswitch.spec
### rpmbuild -bb rhel/openvswitch.spec
### rpmbuild -bb rhel/openvswitch-kmod-rhel6.spec

cd $HOME/rpmbuild/RPMS/x86_64
ls -alF

yum localinstall openvswitch-2.3.0-1.x86_64.rpm

RPM으로 설치
