Nginx 无法处理多个下载

我在使用 NGINX 时遇到了问题。我将为多个（约 4000 人）用户提供文件，他们可能会同时下载多个文件。我已设置 nignx 并尝试下载一个测试文件（centos dvd 1 4GB），一旦我尝试同时多次下载同一个文件，它只允许我先下载一个，然后其他文件会等待我完成第一个下载。我怎样才能在不等待任何时间的情况下提供它。

NGINX.conf：

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

worker_rlimit_nofile 200000;

events {
    worker_connections  10000;

    multi_accept on;
    use epoll;
}


http {
    include   /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_requests 1000;
    open_file_cache max=1000;

    # Added on 26.07.2013 to make files fly!
    tcp_nopush     on;
    client_max_body_size 5G;
    client_body_timeout 120;
    client_header_timeout 120;
    client_body_buffer_size  128K;
    client_header_buffer_size 1k;
    large_client_header_buffers 4 8k;
    send_timeout 60;
    reset_timedout_connection on;
    types_hash_max_size 2048;
    server_tokens off;
    gzip on;
    gzip_static on;
    gzip_min_length 512;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

虚拟服务器配置：

server {

    listen 80;

    server_name *.*.*.*;

    root /usr/share/nginx/html;

    error_log /var/log/nginx/deadz/error.log;
    access_log /var/log/nginx/deadz/access.log;

    index index.html index.htm index.php;
}

我如何才能优化它以便通过一个连接多次提供同一个文件。

如果您需要更多信息，请询问我。

服务器配置：

 server {

    listen 80;

    server_name *.*.*.*;

    root /usr/share/nginx/html;

    error_log /var/log/nginx/deadz/error.log;
    access_log /var/log/nginx/deadz/access.log;

    index index.html index.htm index.php;

    server_tokens off;

    client_max_body_size 700m;
    connection_pool_size 256;
    client_body_buffer_size 1024k;
    client_header_buffer_size 8k;


    limit_rate 125k;
    limit_req zone=one burst=5;

 }

NGINX 配置：

user  nginx;
worker_processes  4;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

worker_rlimit_nofile 20240;

events {
    worker_connections  4000;

    multi_accept on;
    use epoll;
}

http {
    include   /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  off;

    limit_req_zone $binary_remote_addr zone=one:10m rate=1r/s;

    sendfile        on;
    tcp_nopush      on;
    tcp_nodelay     on;

    server_tokens off;

    client_header_timeout 10m;
    client_body_timeout 10m;
    send_timeout 10m;

    client_max_body_size 700m;
    connection_pool_size 256;
    client_body_buffer_size 1024k;
    client_header_buffer_size 8k;

    keepalive_timeout 30;
    keepalive_requests 100000;
    reset_timedout_connection on;
    open_file_cache max=200000 inactive=20s;
    open_file_cache_valid 30s;
    open_file_cache_min_uses 2;
    open_file_cache_errors on;

    gzip on;
    gzip_min_length 10240;
    gzip_proxied expired no-cache no-store private auth;
    gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml;
    gzip_disable "MSIE [1-6]\.";

    include /etc/nginx/conf.d/*.conf;
}

这解决了我的问题:)现在我需要设置 HAProxy 来平衡下载。
