Lab Setup Resources

Basic Lab Environment

A minimal lab environment for practicing Linux administration:

  1. Host System Requirements
    • 8GB+ RAM
    • 50GB+ free disk space
    • CPU with virtualization support
    • Virtualization software (VirtualBox, VMware)
  2. Basic Virtual Machines
    • Linux server distribution (CentOS/Rocky Linux or Ubuntu Server)
    • Minimal resource allocation: 1-2 vCPUs, 1-2GB RAM, 20GB disk
  3. Network Configuration
    • NAT networking for internet access
    • Host-only network for inter-VM communication
    • Static IP assignments for predictable addressing

Intermediate Lab Environment

For more advanced practice:

  1. Multiple Distribution Types
    • RHEL-based (CentOS/Rocky Linux)
    • Debian-based (Ubuntu Server)
    • SUSE-based (openSUSE)
  2. Server Roles
    • Authentication server (LDAP, Active Directory)
    • Web server (Apache, Nginx)
    • Database server (MySQL, PostgreSQL)
    • File server (NFS, Samba)
    • Monitoring server (Nagios, Prometheus)
  3. Network Configuration
    • Multiple subnets
    • Routing between networks
    • Firewall configuration

Advanced Lab Environment

For enterprise-like scenarios:

  1. Infrastructure Services
    • DNS server (BIND)
    • DHCP server
    • Mail server (Postfix, Dovecot)
    • Proxy server (Squid)
    • Load balancer (HAProxy)
  2. High Availability Setup
    • Clustering (Pacemaker, Corosync)
    • Redundant services
    • Shared storage (iSCSI, GlusterFS)
  3. Security Components
    • Intrusion detection (Snort, Suricata)
    • Log management (ELK Stack)
    • Certificate Authority (OpenSSL)
  4. Automation Integration
    • Configuration management (Ansible, Puppet)
    • Containerization (Docker, Podman)
    • CI/CD pipeline integration
