keepalive_timeout參數是一個請求完成之后還要保持連接多久，不是請求時間多久，目的是保持長連接，減少創建連接過程給系統帶來的性能損耗，類似於線程池，數據庫連接池。

 

[root@web01 ~]# cat /application/nginx/conf/nginx.conf

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include      mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                                  '$status $body_bytes_sent "$http_referer" '
                                  '"$http_user_agent" "$http_x_forwarded_for"';
