TSYS FetchApply Deployment Guide

Overview

This guide provides comprehensive instructions for deploying the TSYS FetchApply infrastructure provisioning system on Linux servers.

Prerequisites

System Requirements

• Operating System: Ubuntu 18.04+ or Debian 10+ (recommended)
• RAM: Minimum 2GB, recommended 4GB
• Disk Space: Minimum 10GB free space
• Network: Internet connectivity for package downloads
• Privileges: Root or sudo access required

Required Tools

• git - Version control system
• curl - HTTP client for downloads
• wget - Alternative download tool
• systemctl - System service management
• apt-get - Package management (Debian/Ubuntu)

Network Requirements

• HTTPS access to:
  • https://archive.ubuntu.com (Ubuntu packages)
  • https://linux.dell.com (Dell hardware support)
  • https://download.proxmox.com (Proxmox packages)
  • https://github.com (Git repositories)

Pre-Deployment Validation

1. System Compatibility Check

# Clone repository
git clone [repository-url]
cd FetchApply

# Run system validation
./Project-Tests/validation/system-requirements.sh

2. Network Connectivity Test

# Test network connectivity
curl -I https://archive.ubuntu.com
curl -I https://linux.dell.com
curl -I https://download.proxmox.com

3. Permission Verification

# Verify write permissions
test -w /etc && echo "✅ /etc writable" || echo "❌ /etc not writable"
test -w /usr/local/bin && echo "✅ /usr/local/bin writable" || echo "❌ /usr/local/bin not writable"

Deployment Methods

Method 1: Standard Deployment (Recommended)

# 1. Clone repository
git clone [repository-url]
cd FetchApply

# 2. Run pre-deployment tests
./Project-Tests/run-tests.sh validation

# 3. Execute deployment
cd ProjectCode
sudo bash SetupNewSystem.sh

Method 2: Dry Run Mode

# 1. Clone repository
git clone [repository-url]
cd FetchApply

# 2. Review configuration
cat ProjectCode/SetupNewSystem.sh

# 3. Execute with manual review
cd ProjectCode
sudo bash -x SetupNewSystem.sh  # Debug mode

Deployment Process

Phase 1: Framework Initialization

1. Environment Setup

   • Load framework variables
   • Source framework includes
   • Initialize logging system

2. System Detection

   • Detect physical vs virtual hardware
   • Identify operating system
   • Check for existing users

Phase 2: Base System Configuration

1. Package Installation

   • Update package repositories
   • Install essential packages
   • Configure package sources

2. User Management

   • Create required user accounts
   • Configure SSH access
   • Set up sudo permissions

Phase 3: Security Hardening

1. SSH Configuration

   • Deploy hardened SSH configuration
   • Install SSH keys
   • Disable password authentication

2. System Hardening

   • Configure firewall rules
   • Enable audit logging
   • Install security tools

Phase 4: Monitoring and Management

1. Monitoring Agents

   • Deploy LibreNMS agents
   • Configure SNMP
   • Set up system monitoring

2. Management Tools

   • Install Cockpit dashboard
   • Configure remote access
   • Set up maintenance scripts

Post-Deployment Verification

1. Security Validation

# Run security tests
./Project-Tests/run-tests.sh security

# Verify SSH configuration
ssh -T [server-ip]  # Should work with key authentication

2. Service Status Check

# Check critical services
sudo systemctl status ssh
sudo systemctl status auditd
sudo systemctl status snmpd

3. Network Connectivity

# Test internal services
curl -k https://localhost:9090  # Cockpit
snmpwalk -v2c -c public localhost system

Troubleshooting

Common Issues

1. Permission Denied Errors

# Solution: Run with sudo
sudo bash SetupNewSystem.sh

2. Network Connectivity Issues

# Check DNS resolution
nslookup archive.ubuntu.com

# Test direct IP access
curl -I 91.189.91.26  # Ubuntu archive IP

3. Package Installation Failures

# Update package cache
sudo apt-get update

# Fix broken packages
sudo apt-get -f install

4. SSH Key Issues

# Verify key permissions
ls -la ~/.ssh/
chmod 600 ~/.ssh/id_rsa
chmod 644 ~/.ssh/id_rsa.pub

Debug Mode

# Enable debug logging
export DEBUG=1
bash -x SetupNewSystem.sh

Log Analysis

# Check deployment logs
tail -f /var/log/fetchapply/deployment.log

# Review system logs
journalctl -u ssh
journalctl -u auditd

Environment-Specific Configurations

Physical Dell Servers

• OMSA Installation: Dell OpenManage Server Administrator
• Hardware Monitoring: iDRAC configuration
• Performance Tuning: CPU and memory optimizations

Virtual Machines

• Guest Additions: VMware tools or VirtualBox additions
• Resource Limits: Memory and CPU constraints
• Network Configuration: Bridge vs NAT settings

Development Environments

• SSH Configuration: Less restrictive settings
• Development Tools: Additional packages for development
• Testing Access: Enhanced logging and debugging

Maintenance and Updates

Regular Maintenance

# Update system packages
sudo apt-get update && sudo apt-get upgrade

# Update monitoring scripts
cd /usr/local/bin
sudo wget https://[repository]/scripts/up2date.sh
sudo chmod +x up2date.sh

Security Updates

# Check for security updates
sudo apt-get update
sudo apt list --upgradable | grep -i security

# Apply security patches
sudo apt-get upgrade

Configuration Updates

# Update FetchApply
cd FetchApply
git pull origin main

# Re-run specific modules
cd ProjectCode/Modules/Security
sudo bash secharden-ssh.sh

Best Practices

1. Pre-Deployment

• Always test in non-production environment first
• Review all scripts before execution
• Validate network connectivity
