systemd でのデーモン化

以下のファイルを /etc/systemd/system/nuxt.service として作成

/etc/systemd/system/nuxt.service
[Unit]
Description=nuxt app # アプリケーションの説明(任意)
After=syslog.target network.target
 
[Service]
Type=simple
ExecStart=/usr/bin/npm run start
WorkingDirectory=/home/ec2-user/my-project
KillMode=process
Restart=always
User=ec2-user
Group=ec2-user

[Install]
WantedBy=multi-user.target

上記のファイルの内容を修正した場合は daemon-reload すること

$ sudo systemctl daemon-reload

起動、終了、再起動

systemctl コマンドで実施する

起動
$ sudo systemctl start nuxt.service
終了
$ sudo systemctl stop nuxt.service
再起動
$ sudo systemctl restart nuxt.service
自動起動登録
$ sudo systemctl enable nuxt.service

稼働状況の確認

動作しているかの確認は systemctl status

状況確認
$ sudo systemctl status nuxt.service
● nuxt.service - nuxt app
   Loaded: loaded (/etc/systemd/system/nuxt.service; enabled; vendor preset: disabled)

ログは journalctl で確認可能

$ sudo journalctl -u nuxt.service
