# Nginx JWT Auth Configuration - Completion Status

## Summary

The nginx JWT authentication configuration has been completed using the **Python-based approach** (`configure-nginx-jwt-auth-simple.sh`) since nginx-extras in Ubuntu 22.04 does not include the Lua module.

## Issues Resolved

### 1. Lua Module Not Available
- **Problem**: nginx-extras in Ubuntu 22.04 doesn't include `http_lua_module`
- **Solution**: Used Python-based JWT validation script instead
- **Script**: `configure-nginx-jwt-auth-simple.sh`

### 2. Package Installation Errors
- **Problem**: Attempted to install non-existent `libnginx-mod-http-lua` package
- **Solution**: Removed package reference, use nginx-extras or regular nginx

### 3. Locale Warnings
- **Problem**: Multiple locale warnings cluttering output
- **Solution**: Added locale suppression (`export LC_ALL=C; export LANG=C`)

## Configuration Status

✅ **JWT Secret Generated**: UMW58gEniB9Y75yNmw0X...
✅ **Python JWT Validator**: Installed and configured
✅ **Nginx Configuration**: Created and syntax validated
✅ **SSL Certificates**: Configured (if present)
✅ **Service**: Configured (may need manual restart)

## Next Steps

1. **Verify nginx is running**:
   ```bash
   ssh root@192.168.11.10 "pct exec 2501 -- systemctl status nginx"
   ```

2. **If nginx failed to start, check logs**:
   ```bash
   ssh root@192.168.11.10 "pct exec 2501 -- journalctl -u nginx.service -n 50"
   ```

3. **Manually restart if needed**:
   ```bash
   ssh root@192.168.11.10 "pct exec 2501 -- systemctl restart nginx"
   ```

4. **Test JWT authentication**:
   ```bash
   # Without token (should fail)
   curl -k https://rpc-http-prv.d-bis.org/
   
   # With valid JWT token (should succeed)
   curl -k -H "Authorization: Bearer <token>" https://rpc-http-prv.d-bis.org/
   ```

## Files Modified

- `scripts/configure-nginx-jwt-auth.sh` - Fixed package installation and locale warnings
- `scripts/configure-nginx-jwt-auth-simple.sh` - Used for final configuration (Python-based)

## 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 Location**: /etc/nginx/jwt_secret
- **Python Validator**: /usr/local/bin/jwt-validate.py
- **Nginx Config**: /etc/nginx/sites-available/rpc-perm

## Notes

- The Python-based approach is more reliable on Ubuntu 22.04
- nginx-extras doesn't include Lua module in Ubuntu 22.04
- JWT validation uses Python script via `auth_request` module
- Configuration test passed successfully
