Nginx 配置浏览Linux 系统目录并下载文件

准备工作：

　　安装编译工具及库文件： yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

　　安装PCRE(目的是让Nginx支持Rewrite功能)： 

　　　　下载安装包：wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

　　　　解压安装包：tar -zxvf pcre-8.35.tar.gz

　　　　进入安装目录编译文件：./configure make && make install

　　　　查看版本号(能查看说明成功): pcre-config --version

准备工作到此为止下面是Nginx的配置(Nginx的下载和安装不在此列出):

　　1. 进入Nginx的安装目录，备份配置文件:  cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx_beifen.conf

　　2. 编辑配置文件删除下面默认的server配置,如下： 

　　　　

user root;
worker_processes auto;

error_log /data/wwwlogs/error_nginx.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

events {
  use epoll;
  worker_connections 51200;
  multi_accept on;
}

http {
  include mime.types;
  default_type application/octet-stream;
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 1024m;
  client_body_buffer_size 10m;
  sendfile on;
  tcp_nopush on;
  keepalive_timeout 120;
  server_tokens off;
  tcp_nodelay on;

  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;
  fastcgi_intercept_errors on;

  #Gzip Compression
  gzip on;
  gzip_buffers 16 8k;
  gzip_comp_level 6;
  gzip_http_version 1.1;
  gzip_min_length 256;
  gzip_proxied any;
  gzip_vary on;
  gzip_types
    text/xml application/xml application/atom+xml application/rss+xml application/xhtml+xml image/svg+xml
    text/javascript application/javascript application/x-javascript
    text/x-json application/json application/x-web-app-manifest+json
    text/css text/plain text/x-component
    font/opentype application/x-font-ttf application/vnd.ms-fontobject
    image/x-icon;
  gzip_disable "MSIE [1-6].(?!.*SV1)";

  ##Brotli Compression
  #brotli on;
  #brotli_comp_level 6;
  #brotli_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript image/svg+xml;

  ##If you have a lot of static files to serve through Nginx then caching of the files' metadata (not the actual files' contents) can save some latency.
  #open_file_cache max=1000 inactive=20s;
  #open_file_cache_valid 30s;
  #open_file_cache_min_uses 2;
  #open_file_cache_errors on;

######################## default ############################
########################## vhost #############################
  include vhost/*.conf;
}

在nginx的配置文件的文件夹 conf 下创建vhost 文件夹并创建配置文件 host.conf (名称随意)，配置内容如下(重点)

server {
    listen 80; # 监听端口
    server_name 39.99.247.19; # 域名或IP
    access_log /data/wwwlogs/access_nginx.log combined;
    root /data/wwwroot/default;
    index index.html index.htm index.php;
    #error_page 404 /404.html;
    #error_page 502 /502.html;
　　# 配置完这个服务职能在浏览器中浏览相关目录，但不能下载文件，配置完下面服务之后才能点击文件下载。
    location /download {
      alias /root/workspace/installpackage; #文件所在的文件夹
      autoindex on;
      autoindex_exact_size off;
      autoindex_localtime on;
      charset utf-8,gbk;
    }
　　# 配置完这个 点击文件就能下载了
    location ~ ^/root/workspace/installpackage/(.*)$ { # 当访问该文件夹中任意结尾的文件时把header头修改为下载，这样浏览器就知道是要下载而不是打开路径了
      add_header Content-Disposition "attachment;
      filename=$1";
    }
  }

至此，配置完毕，输入ip:80/download就可以访问目录了，点击文件就能下载了
