How to use nginx to build a file server for uploading and downloading in a container-Nginx-php.cn

1. Install nginx container

In order for nginx to support file upload, you need to download and run the container with the nginx-upload-module module:

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

Copy after login

The container also has nginx- upload-module module and nginx-upload-progress-module module.

NoteThis container isAlpine Linux, there is no bash, and some commands are different from other Linux distributions.

Use the following command to enter the container:

sudo podman exec -it nginx /bin/sh

Copy after login

As a file server, you need to display the local time, which is not the local time by default. Set the local time through the following series of commands:

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

Copy after login

Create the root directory of the file server:

mkdir -p /nginx/share

Copy after login

2. Configure nginx

The path of the configuration file is/ etc/nginx/conf.d/default.conf, as

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 } }

Copy after login

At this point our file service is configured, you need to use the following command to make the configuration take effect:

nginx -s reload

Copy after login

3. Support file upload

1. Configure nginx

The above configuration has completed the configuration of the file server, but the file cannot be uploaded. I want to upload the file. , you also need to make the following configuration:

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; } }

Copy after login

In the above configuration, temporary storage is stored by 1-bit hash, and you need to manually create several directories 0~9 in the upload directory.

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

Copy after login

2. Add upload.html

   上传

Copy after login

3. Add subsequent processing services

You need to install python and the required libraries first

apk add python3 pip3 install bottle pip3 install shutilwhich

Copy after login

python Service source code:

#!/usr/bin/python3 # -*- coding: utf-8 -*- from bottle import * import shutil @post("/upload") def postExample(): try: dt = request.forms.dict filenames = dt.get('file.name') tmp_path = dt.get("file.tmp_path") filepaths = dt.get("file.path") count = filenames.__len__() dir = os.path.abspath(filepaths[0]) for i in range(count): print("rename %s to %s" % (tmp_path[i], os.path.join(dir, filenames[i]))) target = os.path.join(dir, filenames[i]) shutil.move(tmp_path[i], target) shutil.chown(target, "nginx", "root") # 由于shutil.move不会保持用户归属，所以需要显示修改，否则访问时会报403无访问权限 except Exception as e: print("Exception:%s" % e) redirect("50x.html") # 如果是在容器中部署的nginx且映射了不同的端口，需要指定IP，端口 redirect('/') # 如果是在容器中部署的nginx且映射了不同的端口，需要指定IP，端口 run(host='localhost', port=81)

Copy after login

4. Get the upload progress

1. Modify the configuration

# 开辟一个空间proxied来存储跟踪上传的信息1MB upload_progress proxied 1m; server { …… location ^~ /progress { # 报告上传的信息 report_uploads proxied; } location /upload { ... # 上传完成后，仍然保存上传信息5s track_uploads proxied 5s; } }

Copy after login

2. Modify the upload page

   
    
 
 (progress)

Copy after login
