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
For more details, see our Patch Management feature page. The quickest way to actually see it run on your own hosts is a PatchMon Cloud trial (14 days, card required, cancel before day 14 and you are not charged). Or self-host the AGPLv3 Community Edition if you'd rather keep the control plane on your own infrastructure.
