nginx优化优化worker进程链接数量能力worker_connections

性能优化-优化worker进程链接数量能力worker_connections

worker_connections  4096;

worker_connections  20480;

 

如何配置数值大小：

系统的最大打开文件数>= worker_connections*worker_process

   根据系统的最大打开文件数来调整，worker_connections进程链接数量要小于等于系统的最大打开文件数，worker_connections进程链接数量真实数量= worker_connections*worker_process

[root@web01 conf]# ulimit -a|grep "open files"
open files                      (-n) 65535

在主配置文件nginx.conf中配置

[root@web01 conf]# cat /application/nginx/conf/nginx.conf
worker_processes  2;
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;    #添加的
}
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"';
