1. IP Configuration
Servers require a unique IP address to participate in a network and provide services. There are two primary methods of configuration:
Static IP Addressing (Preferred for Servers)
- Assigns a fixed IP address to the server.
- Ensures reliability for services like web servers, DNS, DHCP, mail servers, and file servers.
- Prevents service disruption due to changing IPs (which can happen with DHCP).
- Typically configured at the OS level or via provisioning automation tools.
Dynamic IP Addressing
- Provided via DHCP (Dynamic Host Configuration Protocol).
- More common for client devices or temporary/test environments.
- Not recommended for production servers due to changing leases and inconsistent addressing.
Linux IP Configuration Tools
- ip addr: View and configure IP addresses.
- /etc/network/interfaces: Legacy Debian/Ubuntu configuration file.
- netplan: YAML-based configuration used in modern Ubuntu (e.g., 18.04+).
- nmcli: NetworkManager command-line tool, commonly used in RHEL/CentOS and modern distros.
