nginx优化worker进程数量信息

nginx优化worker进程数量信息worker_processes

worker_processes  2;

说明: worker进程数量主要参照cpu核数信息，要小于或等于服务器的cpu核数*2

      worker_processes数量==cpu核数 

      worker_processes数量<=cpu核数*2

   如何查看CPU的核数信息

      grep processor /proc/cpuinfo|wc -l

      top命令--进入top命令后按数字1查看

   如何查看CPU的颗数信息

      grep 'physical id' /proc/cpuinfo|sort|uniq|wc -l

 

在主配置文件nginx.conf中配置

[root@web01 conf]# cat /application/nginx/conf/nginx.conf
worker_processes  2;    #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;
events {
    #单个进程容许的客户端最大链接数
    worker_connections  20480;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    #访问日志配置
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
