+[Install]
+WantedBy=multi-user.target
+```
+
+---
+
+# 1. Buat user khusus (recommended)
+
+Jangan pakai root.
+
+```
+sudo useradd -r -s /bin/false -d /home/api api
+sudo chown -R api:api /home/api
+```
+
+---
+
+# 2. Buat file log
+
+```
+sudo touch /var/log/delamonganpasarapi.log
+sudo touch /var/log/delamonganpasarapi-error.log
+sudo chown api:api /var/log/delamonganpasarapi*.log
+```
+
+---
+
+# 3. Enable dan start service
+
+```
+sudo systemctl daemon-reload
+sudo systemctl enable delamonganpasarapi
+sudo systemctl start delamonganpasarapi
+```
+
+Cek status:
+
+```
+sudo systemctl status delamonganpasarapi
+```
+
+---
+
+# 4. Monitor log realtime
+
+File log:
+
+```
+tail -f /var/log/delamonganpasarapi.log
+```
+
+Error log:
+
+```
+tail -f /var/log/delamonganpasarapi-error.log
+```
+
+Atau journalctl:
+
+```
+journalctl -u delamonganpasarapi -f
+```
+
+---
+
+# 5. Auto start saat boot
+
+Sudah otomatis karena:
+
+```
+WantedBy=multi-user.target
+```
+
+dan
+
+```
+systemctl enable delamonganpasarapi
+```
+
+---
+
+# 6. Bonus (SANGAT recommended): logrotate
+
+```
+sudo nano /etc/logrotate.d/delamonganpasarapi
+```
+
+isi:
+
+```
+/var/log/delamonganpasarapi*.log {
+    daily
+    rotate 30
+    compress
+    delaycompress
+    missingok
+    notifempty
+    copytruncate
+}
+```
+

+
+# 7. Struktur production yang ideal
+
+```
+/home/api/
+├── delamonganpasarapi
+├── config.json
+└── .env
+
+/var/log/
+├── delamonganpasarapi.log
+└── delamonganpasarapi-error.log
+```
