# Nginx JWT Auth Configuration - Final Status

## ✅ Configuration Complete

The nginx JWT authentication has been successfully configured using the **Python-based approach**.

## Issues Fixed

1. ✅ **Lua Module**: nginx-extras doesn't include Lua in Ubuntu 22.04 - switched to Python-based validation
2. ✅ **Package Installation**: Fixed locale warnings and package installation errors
3. ✅ **Port Conflict**: Removed incorrect `listen 127.0.0.1:8888` from nginx config (port 8888 is for Python service only)
4. ✅ **Service Startup**: nginx now starts successfully

## Configuration Details

- **VMID**: 2501
- **Hostname**: besu-rpc-2  
- **IP**: 192.168.11.251
- **HTTP Domain**: rpc-http-prv.d-bis.org
- **WS Domain**: rpc-ws-prv.d-bis.org
- **JWT Secret**: `/etc/nginx/jwt_secret`
- **Python Validator**: `/usr/local/bin/jwt-validate.py` (running on port 8888)
- **Nginx Config**: `/etc/nginx/sites-available/rpc-perm`

## Service Status

✅ **nginx**: Running and configured
✅ **Python JWT Validator**: Running on port 8888
✅ **Health Check**: `/health` endpoint working
✅ **JWT Authentication**: Configured via `auth_request` module

## How It Works

1. Client makes request to nginx with `Authorization: Bearer <token>` header
2. nginx uses `auth_request` to proxy to Python validator on port 8888
3. Python validator checks JWT token validity
4. If valid, request proceeds to backend (port 8545)
5. If invalid, returns 401 Unauthorized

## Testing

```bash
# Health check (no auth required)
curl -k https://rpc-http-prv.d-bis.org/health

# RPC call without token (should fail)
curl -k -X POST https://rpc-http-prv.d-bis.org/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

# RPC call with valid JWT token (should succeed)
curl -k -X POST https://rpc-http-prv.d-bis.org/ \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <your-jwt-token>" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

## Scripts Used

- **Primary**: `configure-nginx-jwt-auth-simple.sh` (Python-based, recommended)
- **Alternative**: `configure-nginx-jwt-auth.sh` (Lua-based, not available on Ubuntu 22.04)
