## 🔍 **Troubleshooting & Solutions** 🛑

### **1️⃣ Minecraft server did not start (No Systemd service)** 🚫  
**Error:** `Unit minecraft.service could not be found.`  

#### **Solution: Create the service manually** 🛠️  
```bash
nano /etc/systemd/system/minecraft.service
```  
Paste:  
```ini
[Unit]
Description=Minecraft Server ⛏️
After=network.target

[Service]
User=root
WorkingDirectory=/opt/minecraft
ExecStart=/bin/bash /opt/minecraft/start.sh
Restart=always

[Install]
WantedBy=multi-user.target
```  
Enable the service:  
```bash
systemctl daemon-reload  
systemctl enable minecraft  
systemctl start minecraft  
systemctl status minecraft
```

---

### **2️⃣ `server.jar` is empty** 🧨  
**Error:** `ls -l /opt/minecraft/` shows the file is 0 bytes.  

#### **Solution: Replace the empty `server.jar`** 💾  
For **PaperMC**:  
```bash
wget -O /opt/minecraft/server.jar https://api.papermc.io/v2/projects/paper/versions/1.20.4/builds/450/downloads/paper-1.20.4-450.jar
```  
For **Vanilla Minecraft**:  
```bash
wget -O /opt/minecraft/server.jar https://www.minecraft.net/en-us/download/server
```  
Restart the server:  
```bash
systemctl restart minecraft
```

---

### **3️⃣ Firewall (`ufw`) is inactive** 🔥  
**Solution:** Open the Minecraft port:  
```bash
ufw allow 25565/tcp  
ufw allow 25565/tcp6  
ufw enable
```

## 🔧 **Manual Installation** 🗜️  

### **Steps for VM & LXC**  
1️⃣ **Install dependencies**:  
```bash
apt update && apt upgrade -y  
apt install -y curl wget nano screen unzip git openjdk-17-jre-headless
```  

2️⃣ **Create server directory**:  
```bash
mkdir -p /opt/minecraft && cd /opt/minecraft
```  

3️⃣ **Download `server.jar`**:  
```bash
wget -O server.jar https://api.papermc.io/v2/projects/paper/versions/1.20.4/builds/450/downloads/paper-1.20.4-450.jar
```  

4️⃣ **Accept EULA**:  
```bash
echo "eula=true" > eula.txt
```  

5️⃣ **Create a start script**:  
```bash
cat <<EOF > start.sh
#!/bin/bash
java -Xms2G -Xmx4G -jar server.jar nogui
EOF
chmod +x start.sh
```  

6️⃣ **Setup Systemd Service**:  
```bash
nano /etc/systemd/system/minecraft.service
```  
Paste:  
```ini
[Unit]
Description=Minecraft Server ⛏️
After=network.target

[Service]
User=root
WorkingDirectory=/opt/minecraft
ExecStart=/bin/bash /opt/minecraft/start.sh
Restart=always

[Install]
WantedBy=multi-user.target
```  

7️⃣ **Start the server**:  
```bash
systemctl daemon-reload  
systemctl enable minecraft  
systemctl start minecraft  
tail -f /opt/minecraft/logs/latest.log  # Monitor logs 🧾
```
