优化nginx服务对CPU亲和力worker_cpu_affinity

默认情况下可能多个进程跑在一个CPU上或某一核上&＃xff0c;导致Nginx进程使用硬件资源不均匀&＃xff0c;此次优化是尽可能地分配不同的Nginx进程给不同的CPU处理

放置位置&＃xff1a;主标签段&＃xff0c;不在任何区块

配置方法案例&＃xff1a;  

两颗CPU参数配置

   worker_processes  2;

   worker_cpu_affinity 0101 1010;

四颗CPU参数配置

   worker_processes  4;

   worker_cpu_affinity 0001 0010 0100 1000;

八颗CPU参数配置

   worker_processes  8;

   worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;

八颗CPU参数配置

   worker_processes  8;

   worker_cpu_affinity 0001 0010 0100 1000 0001 0010 0100 1000;

在主配置文件nginx.conf中配置

[root&＃64;web01 conf]# cat /application/nginx/conf/nginx.conf
worker_processes  2;
worker_cpu_affinity 0101 1010;   #添加的
error_log logs/error.log;#配置Nginx worker进程最大打开文件数
worker_rlimit_nofile 65535;user www www;
