Ubuntu20.04にSyncthingをインストールする方法

次に、Syncthingサービスを管理するためのsystemdユニットファイルを作成する必要があります。次のコマンドを使用して、両方のサーバーで作成できます。

nano /etc/systemd/system/[email protected]

次の行を追加します：

[Unit]
Description=Syncthing - Open Source Continuous File Synchronization for %I
Documentation=man:syncthing(1)
After=network.target

[Service]
User=%i
ExecStart=/usr/bin/syncthing -no-browser -gui-address="0.0.0.0:8384" -no-restart -logflags=0
Restart=on-failure
SuccessExitStatus=3 4
RestartForceExitStatus=3 4

[Install]
WantedBy=multi-user.target

終了したら、ファイルを保存して閉じます。次に、systemdデーモンをリロードして、構成を適用します。

systemctl daemon-reload

次に、次のコマンドを使用してSyncthingサービスを開始します。

systemctl start [email protected]

Syncthingサービスのステータスを確認するには、次のコマンドを実行します。

systemctl status [email protected]

次の出力が表示されます。

この時点で、Syncthingサービスが開始され、ポート8384でリッスンしています。次のコマンドで確認できます。

ss -antpl | grep 8384

次の出力が表示されます。
