最近在做项目中需要给前端提供文件下载链接，所以借着机会搭建了基于Nginx的文件服务器，特此记录便于日后查阅。

1、配置文件

需要修改 nginx.conf 配置文件（内网地址：10.12.1.215、外网地址：113.98.58.42），内容如下：

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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;
    proxy_request_buffering off;
    proxy_buffering off;
    sendfile            on;

    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

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

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;
    
    server {
      listen    9010;
      server_name localhost;
      charset utf-8;

      include /etc/nginx/default.d/*.conf;
      location / {
          root /usr/local/oas/file;
          sendfile on;
          autoindex on;
          autoindex_exact_size off;
          autoindex_localtime on;
      }
    }    

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

		location / {
                        root /usr/share/nginx/html/PaaS/;
                        try_files $uri /index.html;
                        index index.html;
                }
		
		location /ts/api {
			proxy_set_header X-Real-IP $remote_addr;

       		}

        error_page 500 502 503 504 /50x.html;

                        index index.html;
                }
		

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    } 

    server {
        listen       8081;
        server_name  localhost;
        client_max_body_size 500M;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

                location / {
                        root /usr/share/nginx/html/UUM/;

                        index index.html;
                }


        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

    server {
        listen       8082;
        server_name  localhost;
        client_max_body_size 500M;
        
        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
        
                location / {
                        root /usr/share/nginx/html/CDC/;
                        try_files $uri /index.html;
                        index index.html;
                }

            location = /50x.html { 
        }   
    }
}

注意：这里有几个在文件上传时候的优化点，内容如下：

proxy_request_buffering off; //禁用请求缓冲（不加的话大文件上传可能会在前端报415）
proxy_buffering off; //禁用缓冲（不加的话大文件上传可能会在前端报415）
client_max_body_size 500M; //限制上传文件大小最大500MB

2、验证

将文件上传到 /usr/local/oas/file/upload/sas/auth/ 目录下（文件名为 20200303111734279），然后点击以下链接下载文件到本地，内容如下：

    http://113.98.58.42:9010/upload/sas/auth/20200303111734279

或者你也可以直接访问服务器文件所在目录地址，内容如下：

    http://113.98.58.42:9010/

访问结果，图示如下：
