一、安装nginx容器
为了让nginx支持文件上传,需要下载并运行带有nginx-upload-module模块的容器:
1
2
|
sudo podman pull docker.io /dimka2014/nginx-upload-with-progress-modules :latest sudo podman -d --name nginx -p 83:80 docker.io /dimka2014/nginx-upload-with-progress-modules |
该容器同时带有nginx-upload-module模块和nginx-upload-progress-module模块。
注意该容器是Alpine Linux
,没有bash,有些命令与其它发行版本的Linux不一样。
使用下面的命令进入容器:
1
|
sudo podman exec -it nginx /bin/sh |
作为文件服务器, 需要显示本地时间,默认不是本地时间。通过下面一系列命令设置为本地时间:
1
2
3
4
5
6
|
apk update apk add tzdata echo "Asia/Shanghai" > /etc/timezone rm -rf /etc/localtime cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime apk del tzdata |
创建文件服务器的根目录:
1
|
mkdir -p /nginx/share |
二、配置nginx
配置文件的路径为/etc/nginx/conf.d/default.conf
,作为

10
|
server { …… charset utf-8; # 设置字符编码,避免中文乱码 location / { root /nginx/share ; # 根目录 autoindex on; # 开启索引功能 autoindex_exact_size off; # 关闭计算文件确切大小(单位bytes),只显示大概大小(单位kb、mb、gb) autoindex_localtime on; # 显示本地时间 } } |
此时我们的文件服务就配置好了,需要使用下面的命令让配置生效:
1
|
nginx -s reload |
三、支持文件上传
1. 配置nginx
上面的配置已经完成文件服务器的配置了,但是不能上传文件,想要上传文件,还需要做如下配置:

server { …… charset utf-8; # 设置字符编码,避免中文乱码 client_max_body_size 32m; upload_limit_rate 1M; # 限制上传速度最大1M # 设置upload.html页面路由 location = /upload.html { root /nginx; # upload.html所在路径 } location /upload { # 限制上传文件最大30MB upload_max_file_size 30m; # 设置后端处理交由@rename处理。由于nginx-upload-module模块在存储时并不是按上传的文件名存储的,所以需要自行改名。 upload_pass @rename; # 指定上传文件存放目录,1表示按1位散列,将上传文件随机存到指定目录下的0、1、2、...、8、9目录中(这些目录要手动建立) upload_store /tmp/nginx 1; # 上传文件的访问权限,user:r表示用户只读,w表示可写 upload_store_access user:r; # 设置传给后端处理的表单数据,包括上传的原始文件名,上传的内容类型,临时存储的路径 upload_set_form_field $upload_field_name.name "$upload_file_name"; upload_set_form_field $upload_field_name.content_type "$upload_content_type"; upload_set_form_field $upload_field_name.path "$upload_tmp_path"; upload_pass_form_field "^submit$|^description$"; # 设置上传文件的md5值和文件大小 upload_aggregate_form_field "${upload_field_name}_md5" "$upload_file_md5"; upload_aggregate_form_field "${upload_field_name}_size" "$upload_file_size"; # 如果出现下列错误码则删除上传的文件 upload_cleanup 400 404 499 500-505; } location @rename { # 后端处理 proxy_pass http://localhost:81; } } |
上面的配置中,临时存储时是按1位散列来存储的,需要在上传目录下手动创建0~9几个目录。
1
2

|
mkdir -p /tmp/nginx cd /tmp/nginx mkdir 1 2 3 4 5 6 7 8 9 0 chown nginx:root . -R |
2. 添加upload.html

3. 添加后面的处理服务
需要先安装python及所需的库
