Homework: Local Practice Setup

You already have:

• VirtualBox Ubuntu Server
• 2 CPUs, 4 GB RAM
• Nginx, MySQL, PHP, WordPress installed

Now practice the following:

1. Simulate Oracle VM1 (VPN server)

1. Create a new VM in VirtualBox (VPN-Server).

2. Install Ubuntu Server 22.04 (1 CPU, 1 GB RAM).

3. Install and configure WireGuard:

   sudo apt update && sudo apt install wireguard -y
   
   

   • Create /etc/wireguard/wg0.conf:

     [Interface]
     Address = 10.0.0.1/24
     PrivateKey = <server_private_key>
     ListenPort = 51820
     
     [Peer]
     PublicKey = <client_public_key>
     AllowedIPs = 10.0.0.2/32
     
     

   • Enable IP forwarding:

     echo "net.ipv4.ip_forward=1" | sudo tee -a /etc/sysctl.conf
     sudo sysctl -p
     
     

   • Start WireGuard:

     sudo wg-quick up wg0
     
     

4. Test: Connect from your host PC using a WireGuard client.

2. Simulate Oracle VM2 (Monitoring server)

1. Create a new VM in VirtualBox (Monitor-Server).

2. Install Ubuntu Server 22.04.

3. Install Netdata:

   bash <(curl -Ss <https://my-netdata.io/kickstart.sh>)
