Deployment Aplikasi Flask di Ubuntu 24.04
Siap Dzaq! Berikut adalah **modul lengkap tentang Deployment Aplikasi Flask di Ubuntu 24.04**, dari awal sampai bisa diakses via browser pakai domain atau IP publik. Kita akan deploy pakai **Gunicorn + Nginx** biar production-ready.
---
- 🧰 1. **Install Dependensi Dasar**
```bash sudo apt update && sudo apt upgrade -y sudo apt install python3 python3-pip python3-venv nginx -y ```
---
- 🛠️ 2. **Siapkan Direktori Project**
```bash mkdir ~/flaskapp cd ~/flaskapp python3 -m venv venv source venv/bin/activate ```
---
- 📦 3. **Install Flask dan Gunicorn**
```bash pip install flask gunicorn ```
---
- 🧪 4. **Buat Aplikasi Flask (`app.py`)**
```python
- app.py
from flask import Flask
app = Flask(__name__)
@app.route('/') def home():
return "Hello, Metro TV from Flask on Ubuntu 24.04!"
```
---
- 🧪 5. **Test Jalankan Lokal**
```bash python app.py ```
Tambahkan ini kalau kamu mau bisa akses langsung:
```python if __name__ == '__main__':
app.run(host='0.0.0.0')
```
---
- 🔥 6. **Jalankan dengan Gunicorn**
```bash gunicorn --bind 0.0.0.0:8000 app:app ```
Cek dengan: `http://YOUR_SERVER_IP:8000`
---
- 🧾 7. **(Opsional) Buat File Service Systemd**
```bash sudo nano /etc/systemd/system/flaskapp.service ```
Isi dengan:
```ini [Unit] Description=Gunicorn instance to serve flaskapp After=network.target
[Service] User=ubuntu Group=www-data WorkingDirectory=/home/ubuntu/flaskapp Environment="PATH=/home/ubuntu/flaskapp/venv/bin" ExecStart=/home/ubuntu/flaskapp/venv/bin/gunicorn --workers 3 --bind unix:flaskapp.sock -m 007 app:app
[Install] WantedBy=multi-user.target ```
> Ganti `ubuntu` sesuai user kamu, dan `WorkingDirectory` sesuai folder.
Lalu:
```bash sudo systemctl daemon-reexec sudo systemctl daemon-reload sudo systemctl start flaskapp sudo systemctl enable flaskapp ```
---
- 🌐 8. **Konfigurasi Nginx**
```bash sudo nano /etc/nginx/sites-available/flaskapp ```
Isi dengan:
```nginx server {
listen 80; server_name your_domain.com; # Atau IP kamu
location / {
include proxy_params;
proxy_pass http://unix:/home/ubuntu/flaskapp/flaskapp.sock;
}
} ```
Aktifkan config-nya:
```bash sudo ln -s /etc/nginx/sites-available/flaskapp /etc/nginx/sites-enabled sudo nginx -t sudo systemctl restart nginx ```
---
- 🔐 9. **(Opsional) Tambah HTTPS dengan Let's Encrypt**
Install Certbot:
```bash sudo apt install certbot python3-certbot-nginx -y ```
Dapatkan SSL gratis:
```bash sudo certbot --nginx -d your_domain.com ```
---
- ✅ 10. **Final Cek**
- Akses aplikasi: `http://your_domain.com` atau `http://your_server_ip` - Gunicorn berjalan sebagai service - Nginx mengarahkan trafik ke Flask
---
- 🎁 Bonus: Struktur Folder
``` flaskapp/ │ ├── app.py ├── venv/ └── flaskapp.sock (auto created by gunicorn) ```
---
Kalau kamu mau deployment pakai Docker, atau deploy ke VPS kayak DigitalOcean, tinggal bilang. Mau kubuatin script bash otomatisnya juga bisa.
Mau lanjut ke deploy + domain + SSL?
