基础环境

  • Opendaylight + Mininet （安装好karaf等组件）
  • Open vSwitch 2.3.1

实验步骤

查看控制器ip和交换机的连接状态

登录控制器，查看端口是否处于监听状态

netstat -an|grep 6633

68336330055

登录交换机，查看交换机与控制器的连接情况

root@guest-virtual-machine:/home/guest# ovs-vsctl show
2e6efe16-6875-4feb-8451-7da554fbd3c8
    ovs_version: "2.0.2"
//以上是交换机与控制器未连接成功，需要手动连接，显示以下的“is_connected：true”
root@guest-virtual-machine:/home/guest# ovs-vsctl add-br br-sw
root@guest-virtual-machine:/home/guest# ovs-vsctl set-controller br-sw tcp:192.168.123.10:6633
root@guest-virtual-machine:/home/guest# ovs-vsctl show

68336341161

登陆主机，查看主机与控制器连接情况，如果没连接，需要手动连接

登录交换机，连接控制器（基于OVSDB协议创建一个新的连接）

ovs-vsctl set-manager tcp:192.168.123.10:6640

68336412963

安装sFlow

将sFlow安装包上传至控制器，并解压

68336484626

登录交换机，部署sFlow Agent

ovs-vsctl -- --id=@sflow create sflow agent=s1 target=\"192.168.123.10:6633\" header=128 sampling=10 polling=1 -- set bridge br-sw sflow=@sflow

68336511422

查看已配置的sFlow Agent信息

ovs-vsctl list sflow

68336517033

登录控制器，启动sFlow

68336550170

验证防DDoS攻击

打开浏览器，查看状态

ssh可能会连接不上，需要配置本地VM8的网卡，或者ssh，推荐下面方法

vi /etc/ssh/sshd_config
//最后添加一行
PermitRootLogin yes
//保存后重启服务器即可用远程工具连接Ubuntu主机

首先连接虚拟机

上传安装包，解压缩并进入目录中，启动控制台

root@guest-virtual-machine:/home/guest# tar -zxvf distribution-karaf-0.3.0-Lithium.tar.gz
root@guest-virtual-machine:/home/guest# cd distribution-karaf-0.3.0-Lithium
//启动一(不推荐)
root@guest-virtual-machine:/home/guest# ./bin/karaf
//启动二（后台运行）
root@guest-virtual-machine:/home/guest/distribution-karaf-0.3.0-Lithium# ./bin/start
root@guest-virtual-machine:/home/guest/distribution-karaf-0.3.0-Lithium# ./bin/client -u karaf

安装opendaylight组件

//安装REST API功能
opendaylight-user@root>feature:install odl-restconf
//安装L2交换机和OpenFlow功能
opendaylight-user@root>feature:install odl-l2switch-switch-ui
opendaylight-user@root>feature:install odl-openflowplugin-flow-services-ui
//安装Karaf控制台的md-sal功能
opendaylight-user@root>feature:install odl-mdsal-apidocs
//安装DLUX功能 0.3.0无需安装，0.6.0可以安装
//opendaylight-user@root>feature:install odl-dluxapps-applications
//opendaylight-user@root>feature:install odl-faas-all
//列出所有组件
opendaylight-user@root>feature:list

image-20230324105618145

验证opendaylight功能

首先查看ip地址：

image-20230324110258172

连接控制器

root@guest-virtual-machine:/home/guest# mn --controller=remote,ip=192.168.123.10,port=6633
mininet> pingall
*** Ping: testing ping reachability
h1 -> h2 
h2 -> h1 
*** Results: 0% dropped (2/2 received)

访问web控制器（账号密码admin）

卸载opendaylight组件

opendaylight-user@root>logout

logout退出，回到上一目录中

root@guest-virtual-machine:/home/guest/distribution-karaf-0.3.0-Lithium# rm -rf data
root@guest-virtual-machine:/home/guest/distribution-karaf-0.3.0-Lithium# ./bin/karaf clean
opendaylight-user@root>feature:list -i

查看已安装组件，确认已卸载
