Linux Patch Management Basics
A practical guide to keeping your Linux servers up to date with security patches and updates.
By PatchMon Team
Keeping Linux servers patched is essential for security and stability. Here's a quick overview of the main package managers and how PatchMon helps.
Package Managers by Distribution
| Distribution | Package Manager | Update Command |
|---|---|---|
| Ubuntu/Debian | APT | apt update && apt upgrade |
| RHEL/CentOS/Fedora | DNF/YUM | dnf update |
| Alpine | APK | apk update && apk upgrade |
| Arch | Pacman | pacman -Syu |
Why Automate?
Manual patching across dozens or hundreds of servers is:
- Error-prone: Easy to miss hosts or forget schedules
- Time-consuming: Repetitive work that doesn't scale
- Risky: Delayed patches mean longer exposure to vulnerabilities
PatchMon automates detection, scheduling, and reporting so you can focus on higher-value work.
Next Steps
- Deploy the PatchMon agent on your hosts
- Define patch policies (maintenance windows, approval flows)
- Monitor the dashboard for pending updates and compliance status
