Step-by-Step Setup Guide

Oracle Cloud Free Tier Setup

Step 1: Account Creation 1. Visit https://signup.oraclecloud.com 2. Enter email, password, company name (can be personal) 3. Select country, home region (choose nearest) 4. Enter mobile number untuk verification 5. Add credit card (for verification only, won't be charged)

Step 2: Create Instance

# 1. Login to Oracle Cloud Console
# 2. Navigate: Menu → Compute → Instances
# 3. Click "Create Instance"
# 4. Configure:
   - Name: nara-mining-server
   - Shape: VM.Standard.A1.Flex (ARM)
   - OCPUs: 4
   - Memory: 24GB
   - Boot Volume: 200GB
# 5. Add SSH key (generate new atau upload existing)
# 6. Create!

Step 3: Connect & Setup

# Connect via SSH
ssh -i ~/.ssh/oracle_key ubuntu@<INSTANCE_IP>

# Update system
sudo apt update && sudo apt upgrade -y

# Install essential tools
sudo apt install -y htop curl wget git tmux

# Setup firewall (allow only necessary ports)
sudo ufw default deny incoming
sudo ufw allow 22/tcp  # SSH
sudo ufw allow 8080/tcp  # Web services
sudo ufw allow 5000/tcp  # File manager
sudo ufw enable

# Install Docker (recommended untuk isolation)
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER
newgrp docker

Step 4: ARM Compatibility Notes

# Check architecture
uname -m  # Should show aarch64

# Some software needs ARM versions
# Example: Download ARM64 binaries instead of AMD64
wget https://example.com/software-linux-arm64.tar.gz

# Docker images: Use ARM variants
# Most official images support ARM64 now
# Example: docker run --platform linux/arm64 ubuntu

Hetzner Cloud Setup

sudo ufw allow 8080/tcp
sudo ufw allow 5000/tcp
sudo ufw enable

# Enable fail2ban (brute force protection)
sudo systemctl enable fail2ban
sudo systemctl start fail2ban

Security Best Practices

1. SSH Hardening

# Edit /etc/ssh/sshd_config
sudo nano /etc/ssh/sshd_config

# Change these lines:
PermitRootLogin no
PasswordAuthentication no
PubkeyAuthentication yes
MaxAuthTries 3
ClientAliveInterval 300
ClientAliveCountMax 2

# Restart SSH
sudo systemctl restart sshd

2. Automatic Updates

# Install unattended-upgrades
sudo apt install -y unattended-upgrades

# Configure
sudo dpkg-reconfigure -plow unattended-upgrades

# Or set cron job
sudo crontab -e
# Add: 0 3 * * * /usr/bin/apt update && /usr/bin/apt upgrade -y

3. Firewall Rules

# Default deny
sudo ufw default deny incoming
sudo ufw default allow outgoing

# Allow specific ports only
sudo ufw allow 22/tcp    # SSH
sudo ufw allow 80/tcp    # HTTP (if web server)
sudo ufw allow 443/tcp   # HTTPS (if SSL)
sudo ufw allow 8080/tcp  # Custom web
sudo ufw allow 5000/tcp  # File manager

# Enable
sudo ufw enable

# Check status
sudo ufw status verbose

4. Monitoring & Alerts

# Install monitoring
sudo apt install -y netdata

# Access at http://<IP>:19999
# Configure alerts in /etc/netdata/health.d/

# Or simple script untuk resource monitoring
cat > ~/monitor.sh << 'EOF'
#!/bin/bash
RAM_USAGE=$(free | grep Mem | awk '{printf "%.0f", $3/$2 * 100}')
CPU_USAGE=$(top -bn1 | grep "Cpu(s)" | awk '{print $2}' | cut -d'%' -f1)
DISK_USAGE=$(df / | tail -1 | awk '{print $5}' | cut -d'%' -f1)

if [ $RAM_USAGE -gt 90 ] || [ ${DISK_USAGE%.*} -gt 90 ]; then
  echo "WARNING: High resource usage!" | tee -a ~/alerts.log
  echo "RAM: ${RAM_USAGE}% | CPU: ${CPU_USAGE}% | Disk: ${DISK_USAGE}%" >> ~/alerts.log
fi
EOF
chmod +x ~/monitor.sh

# Add to crontab (check every 5 minutes)
(crontab -l 2>/dev/null; echo "*/5 * * * * ~/monitor.sh") | crontab -

Cost Optimization Tips

1. Multi-Year Prepayment

Many providers offer discounts untuk yearly payment: - Hetzner: No discount (already cheap) - Contabo: No discount - Vultr: No discount - Tip: Monthly gives flexibility untuk switch

2. Use Spot/Preemptible Instances

AWS/GCP: Spot instances (70-90% cheaper)
Risk: Can be terminated anytime
Use case: Non-critical workloads, batch processing
Not suitable: 24/7 mining, trading bots

3. Consolidate Services

Instead of multiple small VPS: - One larger VPS (8-16GB RAM) - Run multiple services dengan Docker - Use reverse proxy (nginx) untuk routing - Savings: 40-60% vs multiple small instances

4. Free Tier Abuse (Ethical)

Legitimate ways to extend free tiers: - Oracle: Can create multiple accounts (different emails) - AWS: $300 credit for 12 months (new accounts) - GCP: $300 credit for 90 days - Azure: $200 credit for 30 days - Vultr: $100 credit (new users)

⚠️ Note: Always follow ToS. Multiple accounts borderline ethical.

5. Monitor Bandwidth

Some providers charge untuk overages
Set up monitoring:

# Daily bandwidth check
vnstat -d

# If approaching limit, throttle non-essential services

Troubleshooting Common Issues

Problem 1: High CPU Usage

Symptoms: Server slow, lagging responses

Diagnosis:

htop  # See what's using CPU
iotop  # Check disk I/O

Solutions: - Kill unnecessary processes - Upgrade instance tier - Optimize application code - Use swap if RAM full

Problem 2: Out of Memory (OOM)

Symptoms: Processes killed, "Killed" messages

Diagnosis:

dmesg | grep -i "killed process"  # See OOM kills
free -h  # Check RAM usage

Solutions: - Add swap space:

sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

Reduce number of services
Upgrade RAM (restart with larger instance)

Problem 3: Network Connectivity

Symptoms: Can't reach services, timeouts

Diagnosis:

ping google.com  # Check internet
ss -tlnp  # See listening ports
sudo ufw status  # Check firewall

Solutions: - Check firewall rules - Verify service is running: systemctl status <service> - Check IP hasn't changed (set static IP if needed) - Contact provider untuk network issues

Problem 4: Disk Space Full

Symptoms: Can't write files, errors

Diagnosis:

df -h  # Check disk usage
du -sh ~/*  # See what's using space

Solutions: - Clean logs: sudo journalctl --vacuum-time=3d - Remove old files - Add block storage (most providers allow attaching additional disks) - Upgrade instance tier

Provider-Specific Tips

Oracle Cloud

Always Free means truly free (with limits)
Don't upgrade to paid accidentally
Monitor usage dashboard regularly
Set up billing alerts (even though free)
ARM instances = warm up slowly (give 5-10 min to reach full performance)

Hetzner

Location matters: Nuremberg (best), Helsinki (cold!), Ashburn (for US)
Snapshots: Create before major changes (€0.012/GB/month)
Volumes: Attach additional storage (€0.044/GB/month)
Networking: Use private networks untuk inter-server communication

Contabo

Expect slower setup: 1-4 hours provisioning time
CPU: Shared, so performance varies
Network: 100Mbit/s on VPS 1, 400Mbit/s on higher tiers
DDoS protection: Automatic, but can cause brief disconnects

Conclusion & Recommendations

For Beginners

Start dengan Oracle Cloud Free Tier
24GB RAM = plenty untuk learning
No cost = no risk
Learn Linux, Docker, basic sysadmin
After comfortable:
