利用OpenDaylight(client)的南向接口netconf对接netopeer2(server)

搭建netopeer2

启动Ubuntu20的docker，将内部830端口映射为主机的22830端口

admin@ubuntu20:~$ docker run -d --name netopeer2_server --privileged -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 22830:830 jrei/systemd-ubuntu:20.04

之前搭建过netopeer2，参考这里。
需要注意的是相关组件的版本可能已经升级，例如libsysrepo.so.6已经更新为libsysrepo.so.7
需要在make install的时候，关注编译出的target的名称和路径
进入docker,创建用户名netconf，设置密码也为netconf

# useradd -m netconf -d /home/netconf -s /bin/bash     
# passwd netconf
New password: 
Retype new password: 
passwd: password updated successfully

启动netopeer2-server

# /usr/local/bin/netopeer2-server -d -v 2

运行OpenDaylight

开始去OpenDaylight的网站下载最新版，最后放弃，原因有二:
- dlux这个GUI已经从源中删除
- netconf连接不上netopeer2-server
从这里下载一个比较老的版本

admin@ubuntu20:~$ wget https://nexus.opendaylight.org/content/repositories/opendaylight.release/org/opendaylight/integration/karaf/0.7.3/karaf-0.7.3.tar.gz
admin@ubuntu20:~$ 
admin@ubuntu20:~$ tar -zxvf karaf-0.7.3.tar.gz

配套的java8安装一下

admin@ubuntu20:~$ sudo apt install openjdk-8-jre-headless  -y

启动ODL(忽略一些报错)

admin@ubuntu20:~/karaf-0.7.3/bin$ ./karaf ________                       ________                .__  .__       .__     __       \_____  \ ______   ____   ____ \______ \ _____  ___.__.|  | |__| ____ |  |___/  |_     /   |   \\____ \_/ __ \ /    \ |    |  \\__  \<   |  ||  | |  |/ ___\|  |  \   __\    /    |    \  |_> >  ___/|   |  \|    `   \/ __ \\___  ||  |_|  / /_/  >   Y  \  |      \_______  /   __/ \___  >___|  /_______  (____  / ____||____/__\___  /|___|  /__|      \/|__|        \/     \/        \/     \/\/            /_____/      \/          Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.

安装必要的组件

opendaylight-user@root>feature:install odl-netconf-connector-all odl-netconf-topology odl-restconf
opendaylight-user@root>

对接

参考官方文档
因为PUT操作需要加payload，直接用curl不方便写，那么就借助postman
下载

admin@ubuntu20:~$ wget https://dl.pstmn.io/download/latest/linux64
admin@ubuntu20:~$ mv linux64 postman-linux-x64.tar.gz
admin@ubuntu20:~$ 
admin@ubuntu20:~$ tar -zxvf postman-linux-x64.tar.gz

在Linux的图形界面运行postman
填入内容如下

PUT http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/netopeer2Headers:
Accept: application/xml
Content-Type: application/xml
Payload:<node xmlns="urn:TBD:params:xml:ns:yang:network-topology"><node-id>netopeer2</node-id><host xmlns="urn:opendaylight:netconf-node-topology">127.0.0.1</host><port xmlns="urn:opendaylight:netconf-node-topology">22830</port><username xmlns="urn:opendaylight:netconf-node-topology">netconf</username><password xmlns="urn:opendaylight:netconf-node-topology">netconf</password><tcp-only xmlns="urn:opendaylight:netconf-node-topology">false</tcp-only><!-- non-mandatory fields with default values, you can safely remove these if you do not wish to override any of these values--><reconnect-on-changed-schema xmlns="urn:opendaylight:netconf-node-topology">false</reconnect-on-changed-schema><connection-timeout-millis xmlns="urn:opendaylight:netconf-node-topology">20000</connection-timeout-millis><max-connection-attempts xmlns="urn:opendaylight:netconf-node-topology">0</max-connection-attempts><between-attempts-timeout-millis xmlns="urn:opendaylight:netconf-node-topology">2000</between-attempts-timeout-millis><sleep-factor xmlns="urn:opendaylight:netconf-node-topology">1.5</sleep-factor><!-- keepalive-delay set to 0 turns off keepalives--><keepalive-delay xmlns="urn:opendaylight:netconf-node-topology">120</keepalive-delay>
</node>

几点说明
- URL最后的device_name(这里是netopeer2)，跟下面payload的node-id需要保持一致
- payload里面的port需要跟端口映射保持一致，当然也可以写docker的IP+830端口
- username/password需要是docker已有的可以ssh登录的用户名/密码
- 放几张截图,认证填入用户名密码是ODL本身的用户名/密码
- 点击"Send"，返回"201 Created"

验证

在主机上用curl获取config信息

admin@ubuntu20:~$ curl -u admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/netopeer2 | python3 -m json.tool % Total    % Received % Xferd  Average Speed   Time    Time     Time  CurrentDload  Upload   Total   Spent    Left  Speed
