关于nginx做为文件下载服务的一套配置

爱是王道

直接贴配置，希望大家多给建议
nginx 基本信息

root@ubuntu:/# nginx -V
nginx: nginx version: nginx/1.0.5
nginx: TLS SNI support enabled
nginx: configure arguments: --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid --with-debug --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_realip_module --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-http_xslt_module --with-ipv6 --with-sha1=/usr/include/openssl --with-md5=/usr/include/openssl --with-mail --with-mail_ssl_module --add-module=/build/buildd/nginx-1.0.5/debian/modules/nginx-echo --add-module=/build/buildd/nginx-1.0.5/debian/modules/nginx-upstream-fair


具体配置

root@ubuntu:/# vim /etc/nginx/nginx.conf
user www-data;
worker_processes 16;
pid /var/run/nginx.pid;
events {
worker_connections 65535;
use epoll;
}
http {
log_format f_nginx  "$remote_addr`$server_addr`$server_protocol`$request_method`$server_port`$bytes_sent`$uri`?$query_string`$status`$request_time`[$time_local]`$http_referer`$http_user_agent";
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 60;
types_hash_max_size 2048;
server_names_hash_bucket_size 128;
client_header_buffer_size 4;
client_header_timeout 60;
client_body_timeout 60;
large_client_header_buffers 16 512k;
#client_body_buffer_size   256k;
client_max_body_size      10m;
include /etc/nginx/mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
gzip  on;
gzip_min_length  1024;
gzip_buffers     16 32k;
gzip_proxied     any;
gzip_types       text/plain application/x-javascript text/css application/xml text/javascript;
limit_zone ltone $binary_remote_addr 10m;
server {
listen   80;
server_name down.test.com;
access_log  /data/logs/down/access.log f_nginx;
error_log /data/logs/down/error.log;
root /data/down;
index index.htm;
limit_conn ltone 10;
limit_rate 50k;
autoindex on;
sendfile on;
tcp_nopush on;
expires 365d;
error_page 400 403 404 500 501 502 503 504 505 /error.htm;
}
}


这样的配置可以承受8000的并发，文件下载在1MB-10MB之间，最高产生带宽500Mbps
