# VPS Server Administration Guide

### What is a VPS?

A VPS is a virtual machine hosted on a physical server. Unlike shared hosting, you get **dedicated resources and full control** over your environment.

#### Advantages of a VPS

* Full **root access** to customize your server
* **Scalable resources** (CPU, RAM, storage)
* **Isolation** from other users
* **Better performance** compared to shared hosting
* **Cost-effective** compared to dedicated servers

Clouduxe VPS solutions are optimized for **websites, applications, and game servers**, with a focus on performance and security.

***

### Step 1: Connecting to Your VPS

Most VPS servers are managed through **SSH (Secure Shell)**.

```bash
ssh root@your-vps-ip
```

* Replace `root` with your admin username.
* Replace `your-vps-ip` with the public IP provided by Clouduxe.

### Step 2: Securing Your VPS

Security should be your first step after deployment.

#### Update the System

```bash
# Debian/Ubuntu
apt update && apt upgrade -y

# CentOS/RHEL
yum update -y
```

#### Create a Non-Root User

```bash
adduser clouduxe
usermod -aG sudo clouduxe
```

#### Configure the Firewall

```bash
# Debian/Ubuntu (UFW)
ufw allow 22
ufw allow 80
ufw allow 443
ufw enable
```

#### Disable Root Login

```bash
nano /etc/ssh/sshd_config
# Change: PermitRootLogin no
systemctl restart ssh
```

> **Warning**\
> Always keep at least one user with sudo privileges before disabling root login. Otherwise, you may lose administrative access.

***

### Step 3: Monitoring VPS Resources

Monitoring ensures your server remains stable and avoids resource bottlenecks.

#### Common Commands

```bash
top        # CPU and memory usage
htop       # Interactive process viewer
df -h      # Disk usage
free -m    # Memory details
uptime     # Server load averages
```

> **Tip**\
> Clouduxe provides integrated **Prometheus and Grafana dashboards** for advanced real-time monitoring.

***

### Step 4: Managing Services

Services such as web servers or databases must be properly maintained.

#### Systemctl Examples

```bash
systemctl start nginx
systemctl stop nginx
systemctl restart nginx
systemctl enable nginx
```

For databases:

```bash
systemctl status mysql
systemctl restart postgresql
```

***

### Step 5: Setting Up Backups

Backups are critical for disaster recovery.

#### Manual Backup

```bash
tar -czvf backup.tar.gz /var/www/html
```

#### Restore Backup

```bash
tar -xzvf backup.tar.gz -C /
```

> **Tip**\
> Clouduxe VPS includes:
>
> * Automated daily backups
> * Offsite redundancy
> * One-click restore options

***

### Step 6: Optimizing Your VPS

To maximize VPS performance:

1. Enable caching (Redis, Varnish)
2. Optimize database queries
3. Use a high-performance web server (e.g., Nginx)
4. Deploy a CDN (Cloudflare + Clouduxe Edge)
5. Scale resources vertically (CPU/RAM) or horizontally (load balancers)

***
