How to Use Linux Control Groups for Resource Limits

Episode 37 of Linux Server Admin with Fexingo dives into control groups (cgroups) — the kernel feature that lets you limit CPU, memory, and I/O per process. Lucas and Luna walk through a real scenario: a runaway PHP-FPM pool consuming all server RAM on a shared hosting box. They explain how to set memory and CPU limits with cgroups v2, how to monitor usage with systemd-cgtop, and why this beats trusting nice values alone. Practical commands, real output, and a warning about the cgroup filesystem hierarchy. Perfect for sysadmins who want to stop one noisy neighbor from killing the whole server. #Linux #ControlGroups #Cgroups #ResourceLimits #Sysadmin #ServerManagement #PHPFPM #MemoryLimit #CPUQuota #Systemd #CgroupsV2 #LinuxKernel #ServerPerformance #NoisyNeighbor #Technology #FexingoBusiness #BusinessPodcast #LinuxServerAdmin Keep every episode free: buymeacoffee.com/fexingo
