    upstream phpfpm {
        server 127.0.0.1:9001;
        keepalive 10;
    }
    
    server{
        keepalive_requests 4096;
        location ~ .*\.php$
        {
             include fcgi.conf;
             fastcgi_pass phpfpm;
             fastcgi_index index.php;
             expires off;
             fastcgi_keep_conn on;
        }
    }
    

    1、upstream中的keepalive设置:
    此处keepalive的含义不是开启、关闭长连接的开关;也不是用来设置超时的timeout;更不是设置长连接池最大连接数。官方解释:

    • The connections parameter sets the maximum number of idle keepalive connections to upstream servers connections(设置到upstream服务器的空闲keepalive连接的最大数量)

    • When this number is exceeded, the least recently used connections are closed. (当这个数量被突破时,最近使用最少的连接将被关闭)

    • It should be particularly noted that the keepalive directive does not limit the total number of connections to upstream servers that an nginx worker process can open.(特别提醒:keepalive指令不会限制一个nginx worker进程到upstream服务器连接的总数量)

    2、keepalive_requests 指令用于设置一个keep-alive连接上可以服务的请求的最大数量。当最大请求数量达到时,连接被关闭。默认是100。
    这个参数的真实含义,是指一个keep alive建立之后,nginx就会为这个连接设置一个计数器,记录这个keepalive的长连接上已经接收并处理的客户端请求的数量。如果达到这个参数设置的最大值时,则nginx会强行关闭这个长连接,逼迫客户端不得不重新建立新的长连接。
    这里设置和php-fpm的pm.max_request一样
