Bind CPU to processes in Centos

Taskset is a CPU adjustment tool that can allocate system tasks to a specified CPU.

This document takes nodejs as an example.

Step 1: query the nodejs Process

Pgrep node1927719283

Step 2: Lock the CPU

Taskset-pc 0 19277 (0 indicates CPU0, and so on) taskset-pc 1 19283

Step 3: Get it done!

A small script can be attached to automatically bind nodejs processes. Assume that there are four nodes, and the CPU is quad-core.

#! /Usr/bin/env bashset-enode_porcess = 'pgrep node | wc-l' if [$ node_process-eq0]; thenecho "nodejs process not found" exit1elsenode1 = 'pgrep node | sort | tr-s "\ n" | awk '{print $1}' 'node2 = 'pgrep node | sort | tr-s "\ n" "| awk '{print $2}'' node3 = 'pgrep node | sort | tr-s "\ n" | awk '{print $3}' 'node4 = 'pgrep node | sort | tr-s "\ n" "| awk '{print $4}' taskset-pc 0 $ node1taskset-pc 1 $ node2taskset-pc 2 $ node3taskset-pc 3 $ node4fi
