\nServer Management
\n\nServer management principles for production operations.\nLearn to THINK, not memorize commands.
\n
\n
\n1. Process Management Principles
\nTool Selection
\n\n\n\n| Scenario | \nTool | \n
\n\n\n\n| Node.js app | \nPM2 (clustering, reload) | \n
\n\n| Any app | \nsystemd (Linux native) | \n
\n\n| Containers | \nDocker/Podman | \n
\n\n| Orchestration | \nKubernetes, Docker Swarm | \n
\n\n
\nProcess Management Goals
\n\n\n\n| Goal | \nWhat It Means | \n
\n\n\n\n| Restart on crash | \nAuto-recovery | \n
\n\n| Zero-downtime reload | \nNo service interruption | \n
\n\n| Clustering | \nUse all CPU cores | \n
\n\n| Persistence | \nSurvive server reboot | \n
\n\n
\n
\n2. Monitoring Principles
\nWhat to Monitor
\n\n\n\n| Category | \nKey Metrics | \n
\n\n\n\n| Availability | \nUptime, health checks | \n
\n\n| Performance | \nResponse time, throughput | \n
\n\n| Errors | \nError rate, types | \n
\n\n| Resources | \nCPU, memory, disk | \n
\n\n
\nAlert Severity Strategy
\n\n\n\n| Level | \nResponse | \n
\n\n\n\n| Critical | \nImmediate action | \n
\n\n| Warning | \nInvestigate soon | \n
\n\n| Info | \nReview daily | \n
\n\n
\nMonitoring Tool Selection
\n\n\n\n| Need | \nOptions | \n
\n\n\n\n| Simple/Free | \nPM2 metrics, htop | \n
\n\n| Full observability | \nGrafana, Datadog | \n
\n\n| Error tracking | \nSentry | \n
\n\n| Uptime | \nUptimeRobot, Pingdom | \n
\n\n
\n
\n3. Log Management Principles
\nLog Strategy
\n\n\n\n| Log Type | \nPurpose | \n
\n\n\n\n| Application logs | \nDebug, audit | \n
\n\n| Access logs | \nTraffic analysis | \n
\n\n| Error logs | \nIssue detection | \n
\n\n
\nLog Principles
\n\n- Rotate logs to prevent disk fill
\n- Structured logging (JSON) for parsing
\n- Appropriate levels (error/warn/info/debug)
\n- No sensitive data in logs
\n
\n
\n4. Scaling Decisions
\nWhen to Scale
\n\n\n\n| Symptom | \nSolution | \n
\n\n\n\n| High CPU | \nAdd instances (horizontal) | \n
\n\n| High memory | \nIncrease RAM or fix leak | \n
\n\n| Slow response | \nProfile first, then scale | \n
\n\n| Traffic spikes | \nAuto-scaling | \n
\n\n
\nScaling Strategy
\n\n\n\n| Type | \nWhen to Use | \n
\n\n\n\n| Vertical | \nQuick fix, single instance | \n
\n\n| Horizontal | \nSustainable, distributed | \n
\n\n| Auto | \nVariable traffic | \n
\n\n
\n
\n5. Health Check Principles
\nWhat Constitutes Healthy
\n\n\n\n| Check | \nMeaning | \n
\n\n\n\n| HTTP 200 | \nService responding | \n
\n\n| Database connected | \nData accessible | \n
\n\n| Dependencies OK | \nExternal services reachable | \n
\n\n| Resources OK | \nCPU/memory not exhausted | \n
\n\n
\nHealth Check Implementation
\n\n- Simple: Just return 200
\n- Deep: Check all dependencies
\n- Choose based on load balancer needs
\n
\n
\n6. Security Principles
\n\n\n\n| Area | \nPrinciple | \n
\n\n\n\n| Access | \nSSH keys only, no passwords | \n
\n\n| Firewall | \nOnly needed ports open | \n
\n\n| Updates | \nRegular security patches | \n
\n\n| Secrets | \nEnvironment vars, not files | \n
\n\n| Audit | \nLog access and changes | \n
\n\n
\n
\n7. Troubleshooting Priority
\nWhen something's wrong:
\n\n- Check if running (process status)
\n- Check logs (error messages)
\n- Check resources (disk, memory, CPU)
\n- Check network (ports, DNS)
\n- Check dependencies (database, APIs)
\n
\n
\n8. Anti-Patterns
\n\n\n\n| ❌ Don't | \n✅ Do | \n
\n\n\n\n| Run as root | \nUse non-root user | \n
\n\n| Ignore logs | \nSet up log rotation | \n
\n\n| Skip monitoring | \nMonitor from day one | \n
\n\n| Manual restarts | \nAuto-restart config | \n
\n\n| No backups | \nRegular backup schedule | \n
\n\n
\n
\n\nRemember: A well-managed server is boring. That's the goal.
