解壓opendayligh軟體包，運作啟動
unzip -o distribution-karaf-0.6.0-Carbon.zip -d /root 配置java環境變量
apt install openjdk-8-jdk -y 檢視java環境變量的安裝包
cd /usr/lib/jvm ls -l 檢視 寫入到開機加載檔案
echo 'export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64' >> /etc/profile
檢查一下寫入情況：
tail -f /etc/profile
加載環境變量：
source /etc/profile 執行啟動：
cd /root/distribution-karaf-0.6.0-Carbon/bin./karaf 安裝元件：
feature:install odl-restconf
feature:install odl-l2switch-switch-ui
feature:install odl-mdsal-apidocs
feature:install odl-dluxapps-applications 然後就可以進行浏覽器通路：
例如：http://192.168.10.3:8181/index.html （）擴充開啟遠端連接配接：
進入：vim /etc/ssh/sshd_config
修改32行注釋取消然後修改yes
重新開機：systemctl restart ssh
開啟開機自啟：systemctl ssh 安裝mininet軟體包
apt --fix-broken install -y 安裝包
dpkg -i mininet_2.2.2-4_amd64.deb 安裝ovs軟體平台

mn --controller=remote,ip=192.168.10.3,port=6653 --topo=single,3 --switch=ovs,protocols=OpenFlow10
--controller=CONTROLLER:指定遠端控制器
remote：遠端主機
ip：遠端位址
port：表示端口
--topo=TOPO：指定拓撲類型
single,m:建立拓撲為星型拓撲，m表示m個主機
--switch=SWITCH：指定交換機類型
ovs：使用交換機的類型 mininet>
