ovs192.168.123.20交换机
pc1192.168.123.30主机1

实验步骤

环境检查

登陆控制器1，查看该端口是否处监听状态

root@guest-virtual-machine:/home/guest# netstat -an | grep 6633
tcp        0      0 192.168.123.10:44024    192.168.123.10:6633     ESTABLISHED
tcp6       0      0 :::6633                 :::*                    LISTEN     
tcp6       0      0 192.168.123.10:6633     192.168.123.10:44024    ESTABLISHED

保证控制器6633处监听状态后，使用root登陆交换机，查看交换机与控制器1的连接情况

连接情况

注：如果连接不成功会显示‘’fail_mode:secure‘’

则需要命令手动在交换机内重连

#ovs-vsctl del-controller br-sw
#ovs-vsctl set-controller br=sw tcp:192.168.123.10:6633

查看主机的ip地址：

控制器的ip地址

注：主机为获取到ip地址，需要手动重连

#ovs-vsctl del-controller br-sw
#ovs-vsctl set-controller br=sw tcp:192.168.123.10:6633

下发流表

切换到交换机，设置OpenFlow协议版本为1.0

root@guest-virtual-machine:/home/guest# ovs-vsctl set bridge br-sw protocols=OpenFlow10

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

image-20230324103545964

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）

image-20230324110537387

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
