優化nginx服務對CPU親和力worker_cpu_affinity

性能優化-優化nginx服務對CPU親和力worker_cpu_affinity

默認狀況下可能多個進程跑在一個CPU上或某一核上，致使Nginx進程使用硬件資源不均勻，這次優化是儘量地分配不一樣的Nginx進程給不一樣的CPU處理

放置位置：主標籤段，不在任何區塊

配置方法案例：  

兩顆CPU參數配置

   worker_processes  2;

   worker_cpu_affinity 0101 1010;

四顆CPU參數配置

   worker_processes  4;

   worker_cpu_affinity 0001 0010 0100 1000;

八顆CPU參數配置

   worker_processes  8;

   worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;

八顆CPU參數配置

   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@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進程最大打開文件數
worker_rlimit_nofile 65535;
 
user www www;
events {
    #單個進程容許的客戶端最大鏈接數
    worker_connections  20480;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    #訪問日誌配置
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
