Nginx的worker_cpu_affinity详解

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_processes 4;
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.
#----------------------------引用文字-结束----------------------------
最关键的地方没说清楚，怎样来表示每个CPU？

经过漫天的搜索和多次尝试发现
详解

如果8核就是：

worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;

如此类推~~
