1.Nginx的worker_cpu_affinity详解.md

配置文件中的worker_cpu_affinity可以用来绑定每个nginx进程所使用的CPU 官方的解释是： #----------------------------引用文字-开始----------------------------

Syntax: worker_cpu_affinity cpumask [cpumask...] Default: none Linux only. With this option you can bind the worker process to a CPU, it calls sched_setaffinity(). For example:

worker_cpu_affinity 0001 0010 0100 1000;```

>Bind each worker process to one CPU only.

```worker_processes 2;
worker_cpu_affinity 0101 1010;```

>Bind the first worker to CPU0/CPU2, bind the second worker to CPU1/CPU3. This is suitable for HTT.
