Ubuntu 22.x Configurations

Network Configuration by netplan

For Example we want to set IPv4 192.168.10.10 on our ubuntu machine, here is a sample of yml file

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: false
      dhcp6: false
     addresses:
      - 192.168.10.10/24
     routes:
      - to: default
        via: 192.168.10.1
     nameservers:
       addresses: [192.168.10.1]

In the above configuration:

• eth0 – is the network interface name
• addresses – is used to configure IPv4 address on an interface. Make sure to define CIDR. You can add multiple addresses here
• nameservers – Set the name servers here. 8.8.8.8 and 8.8.4.4 are Google’s name servers
• routes – This is used to set gateway on your system.

Make sure the IPv4 address belongs to the system network and has the correct gateway Ip address. Once confirmed, save file content and close it.

after editing yml file which should be exist in this path /etc/netplan, should run these 2 commands:

sudo netplan generate
sudo netplan --debug apply

Nginx – Apache

check status of services:

systemctl status apache2
systemctl status nginx
