Nginx 实现文件的上传与下载

天人先生

前言

Nginx是一款高性能、可靠的Web服务器软件，同时用作文件上传和下载
配置

系统版本

[root@127 ~]# cat /etc/redhat-release
CentOS Linux release 8.5.2111
创建用户

[root@127 ~]# useradd -s /sbin/nologin -M nginx  #创建一个nginx用户，且不生成用户目录，和不能登录

创建目录

[root@127 ~]# mkdir -p /export/share/upload/
[root@127 ~]# mkdir -p /export/tmp/upload/
[root@127 ~]# cd /export/tmp/upload/
[root@127 upload]# mkdir 0  1  2  3  4  5  6  7  8  9  state
[root@127 upload]# chown -R nginx:nginx /export/  #文件夹权限管理

[root@127 export]# tree
