Floodlight的安裝
在proxmox上創建一臺虛擬機，操作系統爲ubuntu server 14 .04。
創建好之後，需要連接網絡進行安裝，安裝過程記錄如下：
一、在命令行模式下輸入命令直接安裝：-
apt-get update
-
apt-get install git
-
apt-get install ant
- apt-get install openjdk-7-jdk
-
git clone git://github.com/floodlight/floodlight.git
-
cd floodlight/
-
ant
- java -jar target/floodlight.jar
OVS 的安裝
在proxmox上創建另外一臺虛擬機，安裝OVS
sudo apt-get install openvswitch-controller openvswitch-switch openvswitch-datapath-source
Ubuntu 14.04的OVS版本，已經是2.02，所以默認安裝就可以。不過不同的發行版，ovs的名字會有點不同。
-
ps -ea | grep ovs
-
1216 ? 00:00:00 ovsdb-server
-
1250 ? 00:00:06 ovs-vswitchd
- 2421 ? 00:00:00 ovsdb-client
查看OVS版本
-
ovs-appctl --version
-
ovs-appctl (Open vSwitch) 2.0.2
- Compiled Aug 15 2014 14:31:01
查看 OVS 支持的 OpenFlow 協議的版本
-
ovs-ofctl --version
-
ovs-ofctl (Open vSwitch) 2.0.2
-
Compiled Aug 15 2014 14:31:02
- OpenFlow versions 0x1:0x4
登錄OVS節點：
設置ovs的控制器爲floodlight，10.250.3.10，就是floodlight虛擬機的IP。
- ovs-vsctl set-controller ovs-switch tcp:10.250.3.10:6633
- ovs-vsctl set Bridge ovs-switch fail-mode=secure
# ovs-vsctl show

通過訪問 Floodlight 提供的 Web 管理界面 http://<Host Address>:8080/ui/index.html，我們可以查看 Floodlight 控制器的狀態以及所有連接到 Floodlight 的交換機列表
通過 Floodlight 的 RESTAPI，添加兩條新的規則讓端口 p0 和 p1 可以相互通訊。注意：替換命令行中的 switch 的 ID 爲交換機的 datapath ID
注意curl命令，儘量別用 / 換行
-
curl -d '{"switch": "00:00:d2:3b:94:ce:41:46", "name":"my-flow1", "cookie":"0","priority":"32768","ingress-port":"100","active":"true", "actions":"output=flood"}' http://10.250.3.10:8080/wm/staticflowentrypusher/json
-
- curl -d '{"switch": "00:00:d2:3b:94:ce:41:46", "name":"my-flow2", "cookie":"0","priority":"32768","ingress-port":"101","active":"true", "actions":"output=flood"}' http://10.250.3.10:8080/wm/staticflowentrypusher/json
驗證是否能從端口 p0 發送數據包到 p1
-
