raspberrypiにOpenFlowコントローラーをデーモン化する

Posted at

openflow.serviceの準備

下記のような「openflow.service」ファイルを/etc/systemd/system配下に作成する。

[Unit]
Description = openflow controler

[Service]
ExecStart=/usr/local/bin/ryu-manager /usr/local/lib/python2.7/dist-packages/ryu/app/simple_switch_13.py
Restart=always
Type=simple

[Install]
WantedBy=multi-user.target

正しく設定できているか確認する

root@raspberrypi:/home/pi# systemctl list-unit-files --type=service | grep openflow
openflow.service                       disabled

サービスを起動する。

root@raspberrypi:/home/pi# systemctl start openflow

プロセスが起動していることを確認する

root@raspberrypi:/home/pi# ps -alxg | grep ryu-manager
4     0  1576     1  20   0  37932 33412 SyS_ep Ss   ?          0:03 /usr/bin/python /usr/local/bin/ryu-manager /usr/local/lib/python2.7/dist-packages/ryu/app/simple_switch_13.py
0     0  1599  1571  20   0   3772  1844 pipe_w S+   pts/0      0:00 grep ryu-manager

さらにjournalctlで起動ログを確認する

root@raspberrypi:/home/pi# journalctl

ログの後半に下記の出力が行われていれば正しく起動されている。

OpenFlowコントローラーをデーモン化する。

root@raspberrypi:/home/pi# systemctl enable openflow
